CIPP

Cured In Place Pipe

A cured-in-place-pipe (CIPP) is one of several trenchless rehabilitation methods used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe and Empipe has the capability of repairing pipes ranging from 50mm (2”) to 1200mm (48”). For pipelines larger than 1200mm, we can use SprayWall structural lining.

Empipe uses various methods of CIPP repair depending on the requirement. We offer Volatile Organic Compound (VOC) Free systems when working in storm systems, culverts and outfalls. These systems use felt or fiberglass that is impregnated with resin, and then cured inside of existing pipe. The end result is a strong, ASTM approved product that will provide you with minimal disruption, and maximum return on investment.

Applications for CIPP Include


Large Diameter Point to Point Repair

For diameters 150mm (6”) to 1200mm (48”) we can repair small areas, or entire pipe sections.

Sewer Laterals

From buildings and houses, the drain line that leads from inside to the municipal sewer or lateral, Empipe can re-line the entire existing pipe from beginning to end.

Building Lining

The wastewater piping systems within buildings are suffering from the same corrosion and breakdowns as underground infrastructure. Empipe has the capabilities to line the entire piping system from the roof top the street. Our unique process can provide a completely sealed system including pipe branches and offshoots which means no more costly water leaks and damage to floors, walls and equipment.

CIPP Benefits


The rehabilitated pipe is both sturdy and efficient.

Original pipe life is restored while saving costs of digging and service line re-routing. When compared to a conventional open-cut pipe replacement, in addition to notable cost savings, a cured-in-place-pipe repair can be done in much less time, without large excavations.

This trenchless alternative minimizes damage to existing pavement and inconveniences to the public while reducing long-term street repair costs. A conventional open-cut sewer line replacement takes more than two weeks per block, with significant disruption to traffic and service; a typical CIPP project takes just 1 day and is completed without any excavation.

Without the massive surface disruption of traditional dig-and-replace methods, trenchless processes avoid potentially polluting surface runoff, disturbance of any sub-surface deposits of harmful substances such as lead paint, and the need to dispose of large amounts of waste materials from the original structures.
