Trenchless Sewer and Drain rehabilitation is a method of inserting a new Cured In Place Pipe or CIPP pipe liner into an existing pipe. This is done in most cases with NO DIGGING and can be complete in one day. Existing pipes made of cast iron, clay, orangeburg, concrete, and PVC can all be rehabilitated in sizes from 2" to 12".
