Introducing AP/M’s revolutionary new process for the structural renewal of culverts and sanitary sewer pipe--without backhoes, repaving, traffic detours, flooding or hazardous construction.
It's called Centri-pipe, short for centrifugally-cast concrete pipe.
Let's face it:
corrugated metal, with its propensity to rust and buckle, was not meant to last forever…20 to 30 years is its designed life. Your replacement options include digging and its unavoidable disruption, sliplining with its reduced capacity, or expensive cured-in-place liners. But without digging, without liners, without reduction of capacity, and at significant savings, Centri-pipe creates a new, structurally sound concrete pipe inside the old one. This new pipe is 100% environmentally sound, waterproof, fully sealed from end to end. And it provides highly effective corrosion protection that can double the age of the pipe.
