Inversion Drain Lining Using No Dig Technology

Posted on: December 30th, 2013

Repairing drain lining using No Dig Technology is a proven and established method of inserting a new replacement pipe within an existing damaged pipe without needing to excavate.

The new drain lining is inserted into the damaged pipe by a method called inversion which uses either water or air pressure to fit it tightly within the wall of the existing damaged pipe. When the inversion process is complete the new pipe structure is completely rigid, producing a stronger, reinforced pipe fitted within the existing pipe resulting in a minimal loss of diameter of approximately 6%.

The drain liner is manufactured from a special dense impermeable felt and is designed and tailored to fit exactly the internal dimension of the pipe to be refubished. The thickness of the lining material can be varied according to design specifications required. We recommend the following products:


Drain Lining - Renoline Flexiliner
