Drainage Products


Corrugated plastic pipe is an ideal product to reline or replace other drainage materials that have deteriorated. Used beneath roadways and even under railroad tracks, culverts are usually short in length with both ends of the pipe open to direct water. But they need to be strong to support overburden embankments and heavy traffic loads. Culverts often provide access to commercial developments, homes, farms or livestock facilities, or beneath haul roads used for mining or forestry.

Depending on the diameter, corrugated HDPE pipe meets or exceeds broadly accepted standards. Both Type C (corrugated interior) and Type S (smooth interior) are widely available. Corrugated plastic pipe is approved by most state Departments of Transportation, local municipalities, and regional agencies for use as culverts and in other storm drainage applications.
