Trenchless Sewer Repair technology has produced an alternative to sewer repair frequently referred to as Cured-In-Place Pipe (CIPP). CIPP is where a pipe is constructed "inside the current passage" with certain epoxy resins creating the structural strength of new pipes without damage to structures, floors, hardscape, or landscaping. This method has been in use now for over 25 years. There are two primary types of applications, the 'pull-in-place' (PIP) process and the 'inversion' process.
The extreme advantage to this approach, versus inversion, is that the Invisible Excavation can structurally epoxy line multiple angles and provides the option of only lining the area in need of repair. Invisible Excavation does NOT have to line whole length of the pipe from the point of entry to the point or needed repair which means significant cost savings and flexibility. The other most common method of CIP lining is Inversion, which is an alternate, less innovative method, where the liner itself rolls out from the point of entry as it is filled with water, air or steam and a single time cured-in-place, the end is trimmer to allow for flow.
Drains and sewers may crack due to ground movement, subsidence, tree root infiltration, or corrosion - or they may totally collapse. The result is a structurally defective drain causing repeat blockages or leaks into the surrounding soil. All excavation work is carried out by qualified personnel who have been trained to meet the latest legislation and comply with all Health & Safety regulations.
