Pro-Pipe offers CIPP (Cured-in-Place-Pipe) for trenchless repair of small-diameter pipes ranging from 4 to 15 inches in industrial, commercial and residential areas. This trenchless technology involves placing a special liner in damaged or broken sewer pipe, effectively creating a new pipe within the old one. CIPP repair uses a textile liner tube and a liquid resin to reline the damaged pipe.
After cleaning the sewer pipe and removing all debris, roots and corrosion byproducts, the CIPP trenchless repair impregnates a flexible liner with a two-component resin system and places it inside the deteriorated sewer pipe through existing manholes or access points. The impregnated liner is inverted by means of hydrostatic water column and cured by circulation of hot water, or inverted by means of air pressure and cured by controlled steam.
A new pipe is formed as the CIPP lining cures and hardens within the host pipe. Inspection and testing are performed to make sure the “new” pipe performs as expected, assuming all functions of the host pipe. The pipe-in-pipe solution is solely sustainable. Further, the “new” pipe bears all external loads without the support of the host sewer pipe, providing a complete, structural solution.
Pro-Pipe provides cost-effective CIPP installation for small-diameter pipes in industrial, commercial and residential areas. The CIPP system is an inversion system that allows you to repair pipes by relining them, as opposed to replacing them.
The existing pipe is cleaned and lined with a pre-cut, pre-measured felt liner. The liner is saturated in resin, inserted into the existing sewer pipe, inflated and then cured to harden, taking the shape of the host pipe. The result is a fully rehabilitated reach.
A custom-designed liner tube is impregnated with epoxy and, based on the existing conditions, then inverted or pulled into the existing sewer pipe. The liner materials are selected depending on the pipe condition. Standard liner tubes are used for straight pipes and more flexible tubes are used for pipes with severe bends, angles and transitions from smaller to larger diameters.
Resins are selected according to the job requirements and based on the inversion table. Once the resins are selected, the curing process can be done at ambient temperatures or by adding heat, which allows the curing process to be shortened to one hour.
