Custom Coated Felt for CIPP Liner Fabrication

If you’re looking to bring liner fabrication in-house, E Squared gives you a head start with the same coated felt used in finished liners, without the high barriers to entry. For over 30 years, we’ve specialized in extrusion coating needle-punched Polyester and Polypropylene felt/fleece in widths up to 120”. Whether you provide your own felt or use our locally sourced materials, we deliver polymer-coated base fabrics ready for fabrication. Choose from TPU, TPO, or PE coatings, and get the flexibility to work with felt weights ranging from 3.8 to 35 ounces per square yard.

Why It Works for You:

  • Access the same coated substrates used in pre-made liners

  • Widths up to 120” for custom or large-scale liner builds

  • Use your own felt or source directly from us

  • Polymer coating options:

    • TPU (Thermoplastic Polyurethane)

    • TPO (Thermoplastic Polyolefin)

    • PE (Polyethylene)

  • Supports a wide range of felt weights: 3.8 oz/yd² to 35 oz/yd²

  • Quick turnaround with local sourcing and flexible supply options

    Already fabricating or planning to? E Squared supplies the same high-quality resins used in our substrates as pellets and welding tape ready for your automated equipment. Whether sealing seams or reinforcing stitch lines, our accessories integrate directly into your current system and deliver consistent, reliable results.

    Why It Works for You:

    • Matching welding tape and resin pellets for seamless integration

    • Compatible with automated welding and extrusion systems

    • Same resins as our substrates for material continuity

    • Eliminate sourcing headaches with one trusted supplier

    Single-Pass Extrusion Process

    Our single-pass coating process is built to support your success. We create base materials with strong fiber entanglement and low pinhole frequency, so you start your fabrication with confidence. Every roll is tested throughout production for coating strength, uniformity, and durability, helping you deliver high-performance liners and bladders without the trial and error.

    Why It Works for You:

    • Stronger, cleaner material using single-pass fiber entanglement

    • Fewer pinholes, better bond strength

    • Real-time monitoring during production for consistent quality

    • Every roll is tested for tensile, tear, and adhesion

    • Start your fabrication with a material you can trust

CIPP or cured-in-place pipe is a trenchless pipe lining method in which a liner is inserted into an existing pipe. This liner is treated with a resin that hardens and adheres to the existing pipe surface and effectively seals any cracks or leaks creating a durable, long-term solution.
E Squared offers a wide range of CIPP coated felt products for lateral and mainline pipe rehabilitation applications along with seam tape and welding extrusion resins.  Whether you require a TPO or TPU coated polyester felt, we have the product you need to fabricate your pipes.  Our products have been designed with input from users to ensure that they meet the requirements not only in the fabrication process, but in the field as well.

Advantages of CIPP

– No excavation: CIPP is a trenchless technology, so no excavation is needed. This means that the surrounding area will not be disrupted while the sewer line is repaired.
– Seals leaks and cracks: The CIPP process seals any leaks or cracks in the old pipe, preventing water from leaking into the surrounding soil and destabilizing the ground around the pipeline.
– Better flow capacity: CIPP repair will often have an improved flow capacity which helps to prevent clogs and backups in the future. This process keeps your pipe’s diameter closer to its original size and, thereby, not adversely affecting the flow capacity of the pipeline.
– Extended service life of the pipeline: The CIPP-restoration process increases the service life of the pipeline which can often last decades. This fact alone often makes CIPP a cost-effective, trenchless alternative.
