About Lateral and Mainliner Liners

Need for Lateral or Mainline Liners - Why Us:

Because we have been selling and installing liners within the CIPP lining industry since 1999, and have installed over 2 million linear feet of liners, and sold over 1 million linear feet of liners to contractors.  Pipevision Products Inc. provides a wide range of CIPP liners from 4” to 144” in diameter, in various liner thicknesses, and different types of resins used for different pipes types. FAST Pipelining Inc.’s skilled installers help renew every water or wastewater system, completing every CIPP lining, installation successfully resulting in a tight fit within the host pipe. Our sister company, CIPP Services Inc. provides all the necessary equipment to installers. With trenchless CIPP lining, you minimize disruption and renew the pipelines, especially regaining structural capacity and resist corrosion, costing less upfront than open-trench replacement, minimizing the need for future repairs, saving money in the long run by preventing main breaks, reducing treatment and pumping costs.  

Pipevision Inc.'s CIPP liners are designed to a specifically required thickness determined by the flexural modulus, flexural strength, and tensile strength. Flexural modulus is the controlling factor for round pipes and the strength is the controlling factor as a sealant to the pipe's wall, and tensile strength for internal pressure during applications. Minimum design values for gravity and pressure pipes are outlined in ASTM standards F1216 and F1743 (copies may be purchased from the ASTM website). Because flexural modulus is typically the controlling factor in gravity pipeline design, resin enhancers are often used to increase the flexural modulus of resins allowing for thinner liner designs that improve line flow capacity and reduce material costs. We offer polyurethane or polypropylene coated liners.


Lateral lining for the cured in-place-pipe- lining process is done by inverting the liner through a cleanout. The liner can be directed either upstream or downstream using a cleanout shoe designed by FAST Pipelining and available at CIPP Services. This versatile system is capable of being installed in pipes under foundations, inside walls, or in vertical applications. The lateral lining is an unbeatable trenchless solution for damage and corrosion to residential, hospital, commercial and industrial lateral pipes. Trenchless lateral solutions are ideal for any pipe damage situation, and can even repair residential plumbing pipes with unmatched efficiency.

Cured-in-place-pipe lateral lining solutions is their cost-effectiveness in both the near and far future. With minimal hard labor and operation costs, overheads are low. The strength of these trenchless repair pipes keeps residential, hospital, commercial and industrial lateral lining functional for decades to come, protecting pipes from further damages.

FAST pipeliner crew properly diagnose pipe damages and better present you with renovation options. With CIPP lateral lining repairs can fix and seal any cracks in your lateral lining pipes, even increase flow efficiency, the cured-in-place-pipe liner can reline 4” to 6” transitions. The epoxy base resin in the liner prevents future infiltration.

The trenchless lateral lining can be done on clay pipes, PVC pipes, and any metal pipes. The cured resin-filled liner is molded in-place, as one cohesive body. There are no seams, connections or joints that can break, or corrodible components holding the pipe together. Innovative lateral lining solutions can last for over 50 years added on to the residential, hospital, commercial and industrial lateral pipes with the CIPP cured liner successfully installed. Cured-in-place lining can even repair rainwater pipes with ease and even reline sewer pipes in mere hours. It’s an inexpensive, safe and quick alternative to traditional pipe repair.



The reconstruction of pipelines and conduits by the installation of a resin-impregnated flexible tube that is either inverted or pulled into the original pipeline/conduit and expanded to fit tightly against the said pipeline by the use of water or air pressure. The resin system is cured by elevating the temperature of the fluid may it be air or water pressure used for the inflation to a sufficient enough level for the initiators in the resin to effect a reaction. When a flexible liner is impregnated with the two-component resin system and placed inside of the deteriorated pipe through existing manholes or access points, a new pipe is formed as the liner is cured within the host pipe. The impregnated liner is then inverted by means of the hydrostatic water column and cured by the circulation of hot water, or inverted by means of air pressure and cured by controlled steam. All our CIPP liners are chemically resistant to withstand internal exposure to domestic sewage or stormwater.


Point repair is an appropriate solution for a wide variety of issues seen in different types of pipes. This repair system can be used for CIPP installations or as a stand-alone application over offset joints, pipe separations, and damaged siphons. It can also be used to seal off interior drops and cap off unwanted laterals. It can even replace missing sections of pipe, repair 90° bends, bridge transitions or add extensions to a culvert. Ask about our styrene-free resins and world-class liners allow for efficient and highly successful installations for the rehabilitation or structural renewal of water and wastewater pipe including pressure pipe - potable water and force mains, gravity pipe, not forgetting all pipe size transitions that we offer.


Two Layers CIPP Liner Material
A typical FAST Pipelining liner has two layers: (1) the outer layer of  3.5mm polyurethane-coated polyester felt, (2) the inner layer of 4mm polyurethane uncoated polyester felt.  When properly installed, the wall thicknesses should result in 7.5mm.  FAST Pipelining can provide liners of various thicknesses to comply with the ASTM design specifications as requested.

Large Diameter Multi-Layer CIPP Liners
When constructing large diameter CIPP liners, multiple layers of polyester felt are used to achieve desired pipe wall thickness. The outside coated layer if felt will ultimately result as the new internal pipe wall surface.  Multiple layers of uncoated polyester are inserted into the outer coated layer of felt.  Each layer has a slightly larger diameter than the outer coated layer.  When completed, the excess felt material appears to gather in one spot within the outer coated liner, referred to as bunching.  When installed or inverted, the reversed outside coated liner where the excess materials are needed, fills the large diameter within the host pipe.   

All our proven and comprehensive equipment systems and materials meet the strictest material testing and certification standards, including ASTM, AWWA, and NSF/ANSI 61 certification.

Calibration Hose or Tube
Calibration Hose/Tube is used to drag in liners once Pulled-In-Place (PIP), inflate liners once installed, and also enables inversion liners where the pipe has only one access point to a blind end. It also enables liners to be installed from a single access point.

What is Wet-Out?

For Cured-In-Place-Pipe Lining, the resin is impregnated into the liner.  This impregnation process is called the Wet-Out Process.  Liners can be wetted-out on site, but, economically (cost of the project - taking all tools and equipment required for wetting-out a liner is time-consuming when factoring in the labor cost, hauling of the resin, liner, etc.) and for convenience, usually the liners are wetted-out at a Wet-Out facility where their resin is pre-mixed in large batches and the entire length of the liner is impregnated with the resin during the wet-out process.  The next step is to make sure the resin-saturated liner is kept cool.  The next process is to make sure the liner is placed in a refrigerated truck for cooling.  The temperature of the refrigerated need to stay consistent in order to keep the liner from curing or hardening.  At that point, the liner is ready for delivery to the project location.  Please visit our website for more information on all Wet-Out equipment available for small diameter to large diameter CIPP liners wet-out process.  We also have a Wet-Out Facility on-site to help you with wetting-out the liners for your upcoming projects.
