Trenchless Pipe Repair Systems

Repair damaged sewer and drain pipes without tearing up your yard, driveway or foundation — structural repairs built to last 50+ years.

Perma-Patch

Sectional Point Repair, No Full Reline Needed

Perma-Liner™ has developed a proven method to rehabilitate a 2-foot or 4-foot pipeline section using a "local" sectional repair — no need to reline a pipe manhole-to-manhole to fix just one section.

Perma-Patch uses a fiberglass mat with 100% solids epoxy resin, creating a structural repair with a minimum life span of 50 years. It's designed for 3" to 24" diameter pipelines with cracks, holes and joint separation. The repair is inserted using an inflatable bladder, push rod, or pull cable, then centered and pressed tight against the damaged section to form a new structural pipe wall.
