Description
Product Overview
HDPE dualwall drainage pipe features a smooth interior that helps water flow efficiently and a corrugated exterior that provides structural strength for buried applications. Dualwall pipe resists corrosion, abrasion, and chemical attack better than traditional concrete or metal pipe, and is lighter for easier handling and faster installation. Commonly used in stormwater conveyance, French drains, landscape drainage, culverts, and roadway drainage, this pipe typically meets industry standards such as AASHTO M294 and ASTM F2648 for performance and durability.
