How modular construction methods can be utilized on your next Geomembrane project

The following is an excerpt from an article originally published in geosynthetics Magazine May 2021 https://geosyntheticsmagazine.com/2021/04/01/modular-geosynthetics-construction/

To look at the origin of modular construction you can go back to the 1670s, however, the real boom in America occurred after the second world war when it was utilized to provide fast, low costing housing for workers and returning servicemen. Since then modular construction has been utilized primarily in residential housing and low-rise buildings. In recent years this concept has started to become utilized in high-rise buildings and towers. It is now being used for geosynthetics, and in particular, geomembrane installation, because of the cost and quality advantages.

 

Modular Construction in the form of factory-fabricated geomembranes

The area of geomembranes has experienced innovation related to Modular Construction in the form of factory-fabricated geomembranes. Modular construction involves construction where portions of the final construction are made up of individual sections (“modules”) that are constructed in an off-site controlled manufacturing facility and the modules are assembled at the final building site. For example, roof trusses, wood or concrete tilt-up walls, shower enclosures, tile patterns, and beyond are examples of other products that have adopted modular construction. 

 

The cost difference between factory and field fabricated geomembranes

The Fabricated Geomembrane Institute (FGI) created a cost comparison calculator/spreadsheet that can be used to estimate the installation and CQA cost difference between factory and field fabricated geomembranes in addition to the quality benefits of factory-fabricated geomembranes. The cost comparison calculator/spreadsheet can be downloaded free using the following link: https://www.fabricatedgeomembrane.com/protected/pond-liner-calculator.

The cost comparison does not include the cost of the geomembrane or other required materials. This calculator is “For estimating purposes only” and a formal cost estimate should be conducted for each project. The calculator can be used for other geosynthetics, such as factory-fabricated geotextile.

The major advantage of factory fabrication

The major advantage of factory fabrication is the ability to prefabricate complex geometries or irregular cells and varying slopes and slope breaks rather than trying to cut and size all of the pieces in the field with changing and challenging weather conditions. In addition to complex panel geometries, factory fabrication allows prefabrication of time-consuming geomembrane accessories, such as, pipe boots, ballast tubes, vents, and other custom appurtenances that greatly reduce field time and increase the quality of the welding through the use of controlled factory conditions, different types of welding equipment for large and small, e.g., geomembrane accessories, seaming. For example, dielectric welding or seaming is efficient and produces high-quality welds in the factory but it cannot be used in the field due to its size and power requirements. In the factory, fabricators can also build custom jigs and ways to weld and produce geomembrane panels more efficiently than in the field, which can significantly reduce production costs to the owner.

 

An environmental friendly solution

Modular construction and factory fabrication or geosynthetics also yield a smaller carbon footprint because electrical power generated from renewable sources or less carbon-intensive sources than hydrocarbons can be used for up to 85% of the geomembrane seaming instead of the hydrocarbon energy source(s) used for field fabrication.

Technical fabric: Select the right product for your application

Technical fabrics, textiles, have numerous applications in medical, marine, agriculture, and other industrial sectors. Products like Flexitanks, safety suits, containment units, and inflatable boats depend on the material specifications from the technical fabric manufacturer. A weak or unsuitable choice may lead to costly failure. 

Involving the technical fabric manufacturer early on in the project is a good way to ensure the quality of your project. By approaching the source directly, you can eliminate a lot of associated risks that come with using technical fabric. In this article, we review the most important benefits of communicating directly with the manufacturer and why e2 is the most natural choice for any project you have. 

Why communicate directly with the technical fabric manufacturer?

Numerous projects have their own set of standards and international regulations. The right material choice can depend on a number of variables. Starting from the intended use to the expected environment. 

For instance, consider the example of designing an outdoor Flexitank. The Flexitank intended for the hot and humid environment of Arizona would need to consider the necessary specifications of the fabric that can resist continuous UV exposure. However, the specification would be different for a location further north where temperatures drop to below zero in the winter.   

The right manufacturing partner can guide you through determining fabric qualities that are appropriate for your application. 

The reality is, most installers managing a project requiring Technical fabric will approach their local supplier. Research should be conducted into the requirements needed for the specific application, and material specification should be confirmed will enable you to know if the offered options are limited and if a compromise in favor of easy access will cost in the quality of your project. When it comes to many applications, you should avoid the one-size-fits-all approach. Directly dealing with manufacturers can help you do that. 

The most notable advantages of directly dealing with a Technical fabric manufacturer are:

  • Large variety of Technical fabric selection
  • Customized Solutions
  • Excellent quality backed by a known brand
  • Expert support

The Importance of Correctly Protecting EPS Geofoam Blocks

Construction grade Expanded Polystyrene, better known as EPS Geofoam, is the go-to material for a variety of applications due to its low weight and superior properties. Today, it’s used in building foundations, landscaping, road construction, bridges, and numerous other industries. 

EPS Geofoam, however, has a significant drawback that limits its use in many applications. It rapidly deteriorates when exposed to any hydrocarbon or petroleum product. 

Let’s take a look at the best way you can ensure that doesn’t happen to your projects involving EPS Geofoam.

Consult with a Coated Fabric Expert 

   

Long-standing and durable: EPS Geofoam can last forever when properly protected

What makes EPS Geofoam unique is the fact that it is strong enough to provide a stable foundation, but light enough to not overstress the soil below. The material also has excellent insulating properties and can absorb vibrations in case of an earthquake. 

Even during project execution, using Geofoam blocks will save you time, which translates to lower installation costs. The material also goes through a strict quality control process, so you are always sure to get the best results for your applications.

For road construction applications, the chemical composition of the soil and its interaction with groundwater is a major consideration. EPS Geofoam blocks are impervious to all known substances you can expect to find in the ground. This means that EPS Geomembranes do not have any limit to expected lifespan as the material does not go under any degradation with time. 

Protecting Geofoam with Geomembranes

Despite its inertness with substances found in the ground, EPS Geofoam blocks are surprisingly weak against hydrocarbons. Even limited exposure to a very small amount can cause a lot of damage. For road construction applications, the close proximity with gasoline warrants stringent contingency measures. There might be a spill during transportation or an accident that causes a gas leak on the road, you can’t afford for the road to start deteriorating.

The best way to protect the EPS foundation is to cover the block with a petroleum-resistant geomembrane (PRG). The concept is quite simple. Imagine a chemical-resistant sealed bag that contains your EPS Geofoam blocks. The bag won’t affect the performance of the EPS block but will protect it against any chemical reactions.   

Hydrocarbons are among the harshest chemical compounds and finding materials that completely resist their corrosiveness is difficult. 

Petroleum-resistant geomembranes (PRG) are the best choice for such applications as they are not permeable and do not deteriorate even after prolonged exposure to petroleum compounds. When selecting a PRG you must consider not only the hydrocarbon resistance of the product but also its dimensional stability.  The highest levels of dimension stability can only be achieved by using a fabric reinforced geomembrane.  The strength of the reinforced product will limit the elongation of the PRG to prevent unnecessary settling under load.  Typically a product with 600 pounds or more Breaking strength is being specified by state DOTs.  Currently, the best performing products are reinforced EIA geomembranes.

The specific PRG that should be used can also depend on other factors. The environment, climate, intended application, and your budget are some of the important considerations for your selection. Many state DOTs have specified that a suitable PRG is used on all geofoam projects.

There are limited materials available to protect your EPS Geofoam from petroleum deterioration in the event of a spill. TPU is too expensive and will not last for 20+ years. Standard PVC will not work as the plasticizers in PVC will attack the geofoam. HDPE and LLDPE-R are too stiff to conform to the geofoam block. 

EIA is the product of choice, specifically an EIA that has draping properties that allow it to conform to the geofoam and reduce the potential of creating air pockets between the PRG and the geofoam. 

Your material choice may determine the overall lifespan of the EPS Geofoam so you should be extra careful during the selection process. Making an informed decision can deliver the best results and save you from any future liability. Does that sound overwhelming? Luckily, you’ve got help.

Material Selection Considerations for Efficient Trenchless Pipe Lining Fabrication

 

The growing urban population and aging infrastructures globally have caused an unprecedented growth for trenchless pipe lining solutions. More urban centers now prefer pipe rehabilitation methods that cause minimum disturbance to the day-to-day activities in the area. 

CIPP (Cured in Place Pipe)   is the most common no-dig solution currently used in the market and their applications have evolved from laterals and mainlines to other pipelines as well. CIPPs can handle most curves, minimize the loss of pipe bore, and can be typically installed with the least amount of damage to the road and adjoining areas.

 

The importance of Involving an experienced manufacturer

 Successful implementation of a CIPP solution depends on several factors related to the material combination, production environment, and the installation process. Having the right manufacturing partner for your CIPP applications is more important than you think. From selecting the correct raw material for your application, which is often the first step for success, to ensuring the optimum specifications. Involving an experienced manufacturer can help make the job easier and potentially reduce your overall costs.

 

4 key areas to focus on when selecting CIPP fabric

 

 

1- High level of Customization required per application
As a result of many advancements in CIPP solutions, the typical off the shelf solutions have expanded to many custom products, with more expected.. The number of variables are many from curing methods, pipe diameter, outside temperature, area, and the number of bends/curves are some of the main factors that determine the suitable specification for any job. When creating a product, you need to ensure that your selected coated  felt supplier can deliver specialized solutions of the optimum thickness, weight, and other properties.

 

2- Material compatibility requirements per installation procedure
Building on the previous issue, even the installation procedures vary according to the job. Installers usually rely on different resins and curing methods to warrant the best performance of their trenchless pipe lining solution. Before material selection, you need to ensure that it is compatible with both, the installation method and the application requirements. Your manufacturing partner can help you choose the best solution according to your needs.

 

3- Prevent excessive waste during the fabrication
During CIPP applications you’ll want to prevent excessive waste during the fabrication. As a business, you need to find the perfect balance processing efficiency, performance, and the associated costs. Once again, your material supplier is the perfect entity to help you with this issue.

 

4 – Take advantage of technological advancements
Historically there have been limited sources for CIPP products. today CIPP installers have the option of direct sourcing from a material manufacturer. Things are different today. Advancements in CIPP technology have simplified many processes. Thanks to the latest automated equipment, many large installers are now capable of fabricating pipe products and are innovating with coated felt manufacturers to maximize their profitability.

 

Find the right manufacturing partner for your CIPP applications

The Essentials of Manufacturing CIPP Pipe Lining for Improved Performance

CIPP solutions were first introduced in the 70s. Since then, they have proven their worth in various fields across the globe. manufacturing CIPP pipe lining technology had many limitations at first, but it improved with time. CIPP solutions have advanced considerably in the last few years as new and improved curing methods have been established. Today, CIPPs are much more durable, safer, and are versatile enough for a large variety of industrial applications. 

Because the variety in the Cured in Place Pipe (CIPP) market is quite significant, manufacturing CIPP pipe lining requires a lot of considerations and a wide range of manufacturing solutions.  A manufacturing solution must be able to offer diversity, large fabric handling capacity, multiple seam configuration options, and consistent quality output.  

 

Manufacturing Factors to Consider:

 – The number of layers
 – Seam types
 – Diameter ranges
 – Made to order options
 – Packaging for ease of shipment
 – Absorption of resin at the seam
 – Ability to weld multiple rolls of the same or different thickness simultaneously
 – The positioning of each seam within the different layers
 – The ability to invert without damaging the integrity of the resin at the seam
 – The ability to sew or weld multiple fabrics including Non-wovens or Felt liners that may be coated with polypropylene(TPO), polyurethane(TPU), polyethylene, or PVC

 

Seam Types:

– Hot-air welded overlap seams
– Hot-air welded butt seams
– Sewn seams (Many Variations)
– Sewn seams with welded tape on top
– Sewn seams with extrusion applied on top

The principles for completing finished CIPP products 

All automated systems have the same basic principles in order to complete finished CIPP products. Required in all systems is a heavy-duty unwind to meet the demands of cured-in-place materials and fabrics. A heavy-duty puller to move the product through the system. A guiding and web control closed-looped system to ensure proper tension and alignment of the product into the sewing and welding areas. It may be required to have more than one type of seam bonding (weld, sew extrude) system or multiple combinations. Lastly, it is important to have a good consistent, and quality output system for a product that can be shipped to a customer on-demand or for stock. 

 

The Fabric Manufacturing Process can Determine the Quality and Performance of Your CIPP Solution

Cured-in-place-pipes are certainly a convenient and durable choice of pipe repairs and other applications. However, they undergo a lot of processes before they are ready for deployment in the field. The manufacturing process often determines the quality and other essential performance characteristics of any CIPP solution. You must take extra care that all the technical characteristics, intended applications, seam type, absorption rate, and numerous other factors are being considered. This will ensure consistent and long-lasting performance for your CIPP solution in any location.

The Texas Freeze of 2021: The Way We See It

The supply of materials as a whole in the United States has been in a rapid increase cycle. This didn’t start in 2021 or with the freezing of Texas. It started slowly during the pandemic as people who could afford it started looking for ways to spend their money. They couldn’t travel so they moved to the country, refurbished their home, or bought an RV or a boat. This created record demand for building products, and has driven demand and prices up. This brings us to today.

 

The Recent Texas Storm is a Disaster for Industry and Manufacturing as a Whole

The recent Texas storm is a disaster for industry and manufacturing as a whole. The cold snap caused a variety of problems for the polymer supply chain which supplies many of our building blocks for what we do.  Many production facilities were shuttered last week due to the cold weather.  Many declared force majeure until they can better understand their supply and own manufacturing situations. Most feedstock and polymer plants were not equipped to have a long cold spell. It was estimated that 65% of Ethylene, 23% of Propylene, and 23% of Vinyl Chloride were down last week. Most of these plants were barely keeping up with the increased demand due to record demand in the economy before the crisis with inventories lower than usual.  Some of these plants might have lost more than 2 weeks of production. Whether your business services transportation, medical, or construction you will be affected.  

Chemical Plant start-ups are beginning as I write this. What does this mean to me, you might ask?  These chemicals and polymers are the building blocks for many items. Anything you buy that is made of Polypropylene, Vinyl, Polyethylene, Polypropylene you name it will be affected. There are going to be supply shortages in the short term. There will be increased construction material demand in Texas also to repair the damage. Further increasing demand for the products these companies produced.

 

How does this Affect the US Export Market… 

There will be very few materials for the export market. Most US producers are going to supply their domestic customers first. This means the export market for plastic resins could be almost non-existent from the USA for at least the next month. The US doesn’t export much you might say… This is one of the bright spots of what the US exports. The US is a net exporter for polymer and a major one at that in the world. In 2019 the US exported $65 billion of plastic raw material. We live in a global economy. With the US not exporting it will drive up polymers prices everywhere.

Many manufacturers and converters like us have been dealing with escalating raw material prices even before this due to the increased construction boom mentioned before.  We have been seeing prices rise since early September. We thought we were at the peak. The Texas storm throws all hopes of price declines out the window for the near future. That glimmer of light at the end of the tunnel of the price increases has now been pushed back.

E Squared’s Status in this Uncertain Time

In the last 14 days, we have seen raw material price increases totaling over 10%. This is on top of the 10% rise we have seen in the preceding 4 months. We are happy to say that we do have materials available to supply. Some might not be as lucky. 

 

Buy More than You Need Now While it is Offered

When my father started Ronald Mark Associates back in 1974 during the oil embargo he used to tell me stories about companies not being able to find materials and being there to help out. He was lucky to have connections and was able to bring unrelated companies together. I have spoken to him and others about that time. They all give the same advice. Buy more than you need right now when it is offered. It is better to have than not to have in this uncertain time. It would be worse to shut down a plant than to pay a little extra for peace of mind to keep your plants running. 

 

This Too Will Pass

This will pass. Will some people gouge?.. Yes. But generally, I believe companies and people are good and just trying to pass along what they have been hit with. It’s better to keep your business and customers running than to worry about a month or 2 long blips. The gougers can be dealt with after the crisis has passed. This is a time where relationships are forged and we should help each other out.

The below quote from Geosynthetics by Fred Chuck sums up the situation better than I ever could.

“Through the years, we have seen several hurricanes and petrochemical/plant fires, tariffs, economic crisis, waves of new production, sudden plant outages, numerous Force Majeure declarations and huge swings in energy and feedstock costs, but none of the previous markets, resulting from these sometimes catastrophic catalysts, compare to the extreme environment we currently engage [in].” The combination of these events has accumulated over the past two to three quarters, heavily impacting the industry.  “

Here is the good news as we see it

I always like to look at the bright side.

  1. My kids are back in school.
  2. We can see the end of the pandemic. Vaccines are becoming more available
  3. The storm has passed and Texas will recover fast
  4. We expect demand to stay strong
  5. Interest rates are still historically low.
  6. We will reminisce in 6 months and 5 years and tell stories about this… “ Remember the time …”

ESTER vs ETHER: Which Coated Fleece is Better for Fabricating a CIPP Pipe?

If you’re considering fabricating a CIPP pipe, you’ll need to decide which type of coated fleece liner is right for you. This article compares the two most popular polymers Ester vs Ether used for the CIPP application.  By the end of this short read, you’ll have a better understanding of what to request from your supplier.

 

Coated Fleece used to fabricate CIPP Pipe liners

Coated Fleece used to fabricate CIPP Pipe liners is generally made with needle punch or knitted high-loft fabrics with a polymer coating on one side in order to help maintain pressure as the liner is installed.

A few polymers are used today to coat nonwovens in this application. Thermoplastic Polyolefin(TPO), and ThermoPlastic Urethanes (TPU) are the two most popular we hear about and use. TPO’s can be inexpensive but boardy to work with, while TPU offers a soft hand, superior abrasion resistance, and good high-temperature resistance at a higher price point. 

 

ESTER Vs ETHER: the Chemical comparison

Thermoplastic Polyurethane is made up of 2 main chemistries PolyEther and PolyEster chemistry. Generally speaking, Ester has great chemical and tensile properties, while PolyEther generally exhibits better hydrolytic stability for wet applications, and will generally last longer in wet applications. 

 

Learn About Our Capabilities for CIPP Applications 

 

5 Reasons Ester TPU is more widely used in CIPP applications

1 – Ester based TPU is more chemically resistant than polyethers.

While CIPP is generally considered a wet application, the chemical resistance of the Ester TPU makes it a  better fit in the curing process. When Pipe Liner is curing the resins that have been used to saturate the fleece will begin to give off VOC compounds. Ester is better adapted to resist the effects of this chemical attack.  The chemical resistance of the Ester TPU also helps it survive the harsh conditions in the sewer once the pipe has been lined.

2- Ester TPU has better abrasion and cut resistance
When comparing similar stiffnesses with an Ether TPU, Ester TPU has better abrasion and cut resistance. TPU can be made with varying durometers. Meaning depending on the application the liners can become stiffer or more flexible.

3- Repairing Ester TPU can be an easier process
Repairing Ester TPU can be an easier process because the repair can be made with less volatile solvents such as MEK as opposed to THF which is a more volatile solvent.

4- Ester TPU offers a better bond to fleece
In many cases, the bonding characteristics of Ester TPU’s can give you a better bond to fleece. This becomes important as the pipe liner is inverted and inflated in the tube. Having delamination in a pipe is a disaster.

5 – Ester has the price advantage
Last but not least and generally a driving factor in any industry is that Ester TPU is generally priced lower than Ether-based TPU. There is a pound for pound price advantage of using Ester.

 

Most Common applications for Ether

We generally see the use of Polyether TPU’s in Potable water applications. Potable water applications will need NSF certification. Very few Polyester TPU’s will have this certification due to the Polyester chemistry having poor hydrolysis resistance.

When selecting a medical textile supplier for hospitals or equipment manufacturers, the following three factors are the most important. 

1 – Manufacturing capability

Medical textiles are both versatile and complicated. Different applications require special properties and characteristics like flexibility, recyclability, chemical resistance, and bio-compatibility. The manufacturer you select must possess the capability of handling all your requirements. Otherwise, you’ll waste a lot of time looking for a new supplier anytime you need an innovative solution.

Furthermore, specialized material such as Aliphatic TPU, which has various unique properties and applications, require sophisticated equipment, skills, and processes. Only a small number of manufacturers globally can produce Aliphatic TPU and other similar exclusive materials. If you regularly work with such material, finding the right manufacturer with the required capabilities becomes even more important.   

2 – Logistic constraints

Modern supply chains are quite optimized but the location still plays a huge part in determining the efficiency of your system. It’s better to prioritize suppliers with a local presence as you’ll have direct access to them and you won’t have to deal with extended transit times. Most medical manufacturers need textile products for life-saving equipment and other crucial applications where even slight delays can have severe consequences.

For hospitals needing medical textile products, using local suppliers becomes even more important. Hospitals need a stable, quick, and reliable supply of medical textile for performing surgeries, maintain hygiene standards, and ensure the safety of everyone in the hospital. E2 specializes in textiles that could be used in inflatable medical applications which could be used in mattresses, air compression sleeves, and blood pressure cuffs.

In the recent Covid-19 pandemic, hospitals in the United States faced a severe shortage of PPE, and other essential textile products due to increased international demand. Many hospitals with overseas suppliers faced these shortages because their suppliers prioritized meeting the local demands in their country.

3 – Cost and Quality

Another crucial factor you must consider while selecting a medical textile supplier is the overall quality and the value you are getting for your money. Selecting the cheapest option is not viable in any field. Especially in the medical sector product quality takes precedence over everything. You must remember that the right choice for you may not be the cheapest option, but someone who delivers excellent quality with the shortest lead time. Obviously, commercial viability is an important consideration for any business. However, for medical applications, you must prioritize the technical factors and find the right balance between the cost and quality.

3 Key Benefits of Establishing a Line of Communication with a Geomembrane Manufacturer 

Geomembrane liners are available in a wide variety; reinforced, non reinforced, PVC, EIA, HDPE, LLDPE-R and others as well.  To truly understand the benefits and limitations of each of these products you should establish communications with the actual geomembrane manufacturer. 

The biggest and most obvious challenge faced by general contractors and installers is the fact that each geomembrane material has unique properties, giving each different level of suitability to applications. A wrong choice of geomembrane material can put the entire project at risk. 

The answer to overcoming this challenge is by approaching the source, the geomembrane manufacturer.

Why Factory-Fabrication is Preferred Over Field-Fabricated Geomembranes

For about 50 years, geomembranes have been the go-to choice for civil engineers working on environmental containment of liquids and gases. The nature of their application demands that geomembranes have minimal permeability to prevent anything from leaking into the soil it is protecting. Engineers rely on geomembranes for a variety of applications ranging from reservoirs, agricultural water to industrial wastewater, or hydrocarbons. Therefore, depending on the application, even the smallest error in fabrication or installation can have severe consequences.

 

Request a consultation with a geomembrane expert 

 

Generally, geomembrane suppliers and experts are the last to be involved in an ongoing project. So, it is better to know the characteristics of both pre-fabricated and field-fabricated membranes beforehand. In this article, we will address the performance benefits of pre-fabricated geomembranes to give you the important data required to make an informed decision regarding the installation method.

 

What is the role of seams in geomembrane installations? 

Just like how a chain is as strong as its weakest link, a geomembrane is as tough as its seam or welded joint. The points where two geomembrane panels join can be a source of leakages and other flaws in the case of a subpar seam.

The seams need to have enough shear strength and peel strength to avoid damages during installation. For this reason, seam testing is a critical part of the installation process. For factory-fabricated geomembrane liners, the seam inspection can take a fraction of the time required in comparison to test field-fabricated seams.

 

Factory vs field fabricated geomembranes

Installing geomembrane liners may seem to be simple, but the process is everything but straightforward.  Typically, geomembrane liners are fabricated in two ways; either field fabricated during installation or factory-fabricated in modular panels for final field assembly.

We’ll take a detailed look at both options.

 

Field fabricated geomembranes

In this method, geomembrane panels are fabricated and welded on site. For HDPE geomembranes, this approach is considered the ideal choice. However, the field fabrication process can present multiple challenges that could adversely affect the integrity of the seams. Things such as dirt, terrain, and steep slopes can affect the quality of the work and welds that could lead to future leaks. Not only that, field fabrication procedures have to be adjusted for weather conditions and sunlight exposure.

Field fabricated geomembrane demand high installation costs as they require more workers as well as constant destructive testing and inspection of seams during the process. This, along with the high probability of damage to liners, makes field fabricated geomembranes less preferred when using geomembranes other than HDPE.

 

Factory-fabricated geomembranes

Most of the work in this installation process takes place within a controlled environment. Here, flexible membranes are fabricated in the factory and then rolled or folded for transportation to the project site. These panels are welded on a flat concrete surface usually. The process can drastically reduce the welding time and provides consistent seams. Inspecting and testing the seams in a factory is also more consistent. Due to the controlled environment seam samples are easily conditioned for immediate testing allowing for any required process adjustments to be made sooner. 

 Pre-fabricated panels are then delivered directly to the job site to be installed. These large panels are already certified and tested requiring that only the perimeter welds be tested on-site.     

 

Reduced installation costs with better results

The entire process reduces installation costs and delivers quality results. Moreover, the on-site installation time is significantly narrowed especially for large-scale projects. Factory fabricated seams are more consistent and hence, less prone to leaks. This method is also entirely suitable for a smaller crew that has limited equipment.  Over the years, factory-fabricated geomembrane liners have enjoyed tremendous popularity in the market, and as discussed, their popularity is well deserved.

Higher Quality, Faster, and Cost-Effective:

Pre-Fabricated Geomembranes Check All Boxes!

Pre-fabricated geomembranes are the preferred method for contractors and installers who have a narrow installation schedule and may, depending on the time of year and geography, be racing the clock to project completion. On the other hand, field fabricated geomembrane panels are subjected to challenges brought on by weather and other unfavorable working conditions on-site. For contractors who are looking for better quality liners at a cost-efficient rate, factory-fabricated geomembrane is the ideal solution for them!
