UV-Cure Spot Repair

Pro-Pipe provides advanced CIPP sectional repair for main and lateral pipelines using the Cosmic system, complete with ultra-violet cured factory impregnated fiberglass resin laminates, forming a complete circumferential lining within a seven-minute cure. The system offers innovative technology and superior materials required to ensure high quality and long lasting CIPP trenchless point repairs. Used to rehabilitate pipes ranging in diameter from 6 to 36 inches of any material, pipes are cured in minutes with a wall stronger than industry standard felt CIPP liners (an excellent solution for cracks, root intrusion, separated joints, infiltration/ exfiltration, corrosion, mis-cut lateral connections and more).

  • 7-minute UV Cure
  • Install in Live Flow (under most circumstances)
  • No mixing of Resin in the field (factory wet-out & delivered enclosed, in a gel-state)
  • Epoxy paste can be applied at the ends for an adhesive seal
  • Resin is only reactive to UV-light, therefore 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 allows for future rehabilitation of the remaining pipe segment
  • Fully structural repair designed as 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 Globally)
  • Does not shrink

The material is an ECR (E-Glass, Corrosion Resistant) 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 (in controlled conditions) and is partially cured during the wet-out procedure transforming the resin into a gel-state for safe handling and transportation (no hardeners are required for onsite field mixing). The resin and glass laminate configuration, as a whole, eliminate 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 pipe. The material is available in a variety of wall thicknesses, and can be overlapped for extended lengths (typical repair is 4ft).

Typically, resin does not have adhesive properties. To ensure a water-tight seal between the sectional liner and the host pipeline wall, a manufacturer-supplied A-B Epoxy system is supplied and incorporated into the repair procedure. When the glass laminate (gel-state) is wrapped on the bladder, the A-B epoxy paste is mixed on a flat surface and applied towards the laminate ends.

The applicator (silicone bladder) extends beyond the laminate edge therefore 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.
