What is trenchless pipe lining?


Trenchless pipe lining falls under two categories – Cured-in-place pipe (CIPP) and cast-in-place pipe (CIP).

Cured-in-place pipe, or CIPP, is a trenchless pipe repair method that has a design life of 50 years. CIPP is made of resin-coated fabric that is cured in place using heat or ultraviolet light. This creates a new pipe within an existing one, without any excavation.

 xCast-in-place pipe, or CIP, is a trenchless pipe repair method that involves the installation of a new pipe within the existing one. Usually done in pipes that have a larger diameter, cast-in-place pipe lining involves pouring liner material into a pre-designed formwork (e.g., an existing pipe). The liner is then allowed to cure and harden in the appropriate shape, creating a new pipe inside the old one.

Trenchless pipe lining is a quick, cost-effective, and minimally disruptive way to repair pipes. It can be used to repair sewer lines, water lines, and other types of pipes. Trenchless pipe lining has a number of benefits over traditional dig-and-replace methods and can be designed to be a stand-alone solution even if the existing host pipe completely deteriorates.
