DOUBLE Q® is a dual wall HDPE pipe that is annularly corrugated on the exterior and has a smooth interior for increased flow capabilites. DOUBLE Q® pipe is a high performance product that is strong and durable, and offers soil tight joints. DOUBLE Q® is made of high density polyethylene plastic and lends itself to heavy construction projects:

• Road culverts
• Agricultural projects
• Environmentally sensitive projects

It is also lightweight and easier to install than other types of materials, yet it offers superior weather resistance. DOUBLE Q® won't corrode, crack or shatter, and it is not affected by freeze/thaw cycles.

DOUBLE Q® pipe is available in diameters of 12 inches to 48 inches in 24 foot and 30 foot lengths. Pipe with perforations, with or without an external filter fabric applied, and select sizes are also available by special order. Call for more information.
