And the process is cost-effective, especially when compared to cured-in-place pipe (CIPP) in large diameter pipe.

CentriPipe also requires smaller staging areas than most competing solutions.

The process creates a new pipe within the old sewer or culvert, a pipe that is structurally sound (independent of the original substrate), waterproof and long lasting. “And since specifications were written in a way that permitted CCCP, we went for it - it’s the largest CentriPipe project in Colorado, so far.”ĬentriPipe is a technology developed by AP/M Permaform, based on a spincasting sled that is inserted into pipe and withdrawn, while an operator on the sled monitors the withdrawal rate to spray thin, even, layers of high-strength cementitious mortar that adheres to most substrates, including CMP, brick and clay. “There were a total of 10 large culverts in this particular project (CDOT #20158R, Region One, covering the Greater Denver Metro and Central Colorado area) and seven seemed like good candidates for CCCP,” says Paul Snyder, president of American West Construction LLC (AWC). Centrifugally cast concrete pipe (CCCP) is an established trenchless rehabilitation solution for large diameter sewers and culverts and is gaining ground with state departments of transportation (DOTs), which are traditionally conservative when adopting new technology.Ī recent culvert rehabilitation project, let by the Colorado Department of Transportation (CDOT) is groundbreaking in this regard.
