The unusually large diameter PVC conduit was developed by CertainTeed Corp in response to the expanding US telecommunications and electrical utility industry, which require easy-to-install and cost effective large diameter trenchless PVC conduit options that hold over fused HDPE pipe.

Developed for use in trenchless electrical and telecom duct applications, Certa-Com features the high strength and flexibility needed for horizontal directional drilling installations and is available in 10 foot or 20 foot lengths that assemble quickly and do not require fusion or solvent welding.
