C.I.P.P. Pipe Repairs or "Cured in Place Pipe"

The CIPP or Cured in Place Pipe method is a frequently asked for method of trenchless sewer and drain pipe repair because of it's cost savings and effectiveness.  

Residential, Commercial and Municipal building owners and managers find this method most attractive because its fast and great for both horizontal and vertical piping and drains.

In buildings with vertical piping, CIPP repairs can usually be completed from the roof of the building without any invasive demolition such as tearing down walls or ceilings.

If your building needs cured in place pipe repairs on horizontal pipes, only a small access point needs to be created at either end of the affected pipe.

The CIPP method of sewer repair involves inverting, or pulling, a resin-saturated felt tube with a liner through the damaged pipe. The tube is made of a polyester or fibreglass cloth so that it is suitable for resin impregnation.

The type of liner is chosen based on the pipes purpose and what type of liquids it will be carrying. Pressure (either water or air) is then used to help the tube take the shape of the pipe before the resin soaked liner is cured, creating a tight fitting and jointless replacement pipe that is corrosion resistant.

Because different liners are chosen for the pipe’s purpose, it's important to know beforehand what the pipe carries. There are several different liners for the different liquid materials carried by sewage and drain pipes (like potable water, pressurized water, hot/cold water, grey water, sewage and more). Choosing the right liner for the right pipe and purpose is an important part of CIPP working correctly as a permanent repair.

After the process is complete, our professionals can then inspect the repair job via closed-circuit television (CCTV) to make sure the job is done to our high standards.
