The materials used in the Cured In Place Pipe (CIPP) are bi-directional structural mesh and resins, whose properties, quantity, thickness, density and dosage are optimised to meet the required standard.
Steps Of patch repair application
In this process, a fiber-glass laminate is impregnated with resin and fixed on a packer, then moved to the defective spot while being monitored by a CCTV camera, positioned there and pressed against the host pipe. Then inflate the packer with the wetted fiber-glass mat against the inner wall of the host pipe. The cured liner covers the entire surface of the repaired pipe section without any hydraulic changes, i.e. without obstructing the sewage flow. The pipe-in-pipe system so obtained and the host pipe form a unit.
IAC will determine the length of the lining for each insertion; insert the composite material, carried by a mandrel (packer) and a cable drive. The material is allowed to cure, adhere and hardens for the prescribed number of hours. Mandrel (packer) is then deflated and removed, procedure is resumed for another section.
