Corrugated Metal Pipe

Corrugated metal pipe, or CMP, has been the drainage pipe of choice for engineers and project specifiers for over 100 years.  With its various steel thicknesses, CMP provides the predictable strength, durability, and value that today’s projects demand.  Whether your project has fill heights in excess of 100′, service life requirements of 100 years, or extreme site and environmental considerations, corrugated metal pipe has you covered.

High Density Polyethylene (HDPE)

High density polyethylene (HDPE) piping systems have been used for municipal and industrial water applications for over 50 years. Its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. HDPE systems are cost-effective to install and have long-term maintenance cost savings, and also allow for cheaper installation methods. PE is less likely to have problems with root intrusion, and provides integrity for the pipeline, even when installed in unstable soils.



Used mainly in stormwater and drainage applications, SDR 35 is a medium-strength pipe that falls between Schedule 20 and Schedule 40 PVC pipe. It comes in 14' lengths, and is compatible with the standard SDR 35 gasketed fittings. "standard dimension ratio" is widely used in the PVC pipe industry. This refers to a term that is obtained by dividing the average outside diameter of the pipe by the minimum pipe wall thickness.
