UV Pipe Lining

UV-Cured CIPP Lining Repair

UV Pipe Lining Is a Better Solution

The UV Cured-in-Place-Pipe (CIPP) lining process creates a stronger, longer-lasting pipe than can be achieved using steam or water curing with felt, resin-impregnated liners. This advanced technique utilizes fiberglass-reinforced, UV light-cured CIPP liners that are pulled in place to create an extremely durable “pipe-within-a-pipe.”

UV-Cure Spot Repair

Pro-Pipe provides state-of-the-art UV-cured CIPP services for main and lateral sewer pipes using the Cosmic system. This system comes complete with ultraviolet (UV)-cured, factory-impregnated fiberglass resin laminates and forms a complete circumferential lining within a seven-minute cure time. The system’s innovative technology and superior materials ensure high-quality, long-lasting CIPP trenchless point repairs.

The Cosmic system rehabilitates pipes of any material ranging in diameter from 6” to 36”. Sewer pipes are cured in minutes and the result is a wall stronger than mandated for industry-standard felt CIPP liners. This solution is excellent for cracks, root intrusion, separated joints, infiltration/exfiltration, corrosion, mis-cut lateral connections and other problems.

Benefits of Our UV-Cured CIPP Lining Repair

  • Seven-minute UV CIPP lining
  • Install in live flow conditions (under most circumstances)
  • No mixing of resin in the field (factory wet-out and delivered enclosed in a gel state)
  • Epoxy paste can be applied at the ends for an adhesive seal
  • Resin is reactive only to UV light; no premature set-off as with ambient cure systems
  • Glass reinforcing increases structural strength, mitigates shrinkage and allows for a thin wall
  • The thin wall permits future rehabilitation of the remaining pipe segment
  • Fully structural repair designed to be a 50-year solution
  • Tapered edge is bonded to the host wall
  • Fraction of full-length lining cost or excavation cost
  • Extensive performance history (12+ years in the U.S. and worldwide)

About the UV Cure System’s Materials

The liner material is an E-glass, corrosion-resistant (ECR) fiberglass mat pre-impregnated with either Palatal P-92 Polyester light reactive resin or Atlac E-Nova RE 3475 Vinyl Ester light reactive resin. The wet-out procedure is performed at the manufacturer’s plant in Austria (under controlled conditions). During this procedure, partial curing occurs. The partial curing transforms the resin into a gel state for safe handling and transportation; no hardeners are required for on-site field mixing.

The resin and glass laminate configuration eliminates any need for inner and outer coatings. The manufacturer provides a specially designed A+B epoxy for application over the outside of the resin at the laminate ends to create an adhesive seal between the repair and the host sewer pipe. The material is available in a variety of wall thicknesses, and can be overlapped for extended lengths (typical repair is 4 feet long).

Resin does not usually have adhesive properties. To ensure a watertight seal between the sectional liner and the host pipeline wall, a manufacturer-supplied A+B epoxy system is incorporated into the repair procedure. When the glass laminate (in gel state) is wrapped on the bladder, the A+B epoxy paste is mixed on a flat surface and applied toward the laminate ends.

The applicator (silicone bladder) extends beyond the laminate edge, thereby creating a beveled edge against the host wall, compressing the epoxy between the host wall and resin laminate. The result is a sealed, smooth transition to the sectional liner.

UV-Cure Lateral Seals (Top Hats)

The Cosmic Top Hat™ provides a seal between the main pipeline and a lateral connection. The resin-impregnated, fiberglass laminate is shaped to fit within a lateral service connection and wrap around the main sewer line, sealing the connection (including a 360-degree wrap). Epoxy is utilized in addition to the resin to provide an adhesive, watertight seal.
