Polyethylene drainage pipe
75, 100, 150mm ADS

Smoothwall pipe is available in 10' (3m) lengths; 3", 4" and 6" (75, 100 and 150mm) diameters, and joins with simple, secure bell-and-spigot connections. The pipe is made with a white, high density polyethylene layer around a black polyethylene core to form a lightweight pipe with excellent beam stiffness.

Meeting ASTM F810, Smoothwall is very popular for sanitary leach field use because of its low cost, large perforations, and high beam strength when compared to singlewall perforated polyethylene pipe. Beam strength is a measure of the stiffness of a pipe in the longitudinal direction. Because Smoothwall is relatively stiff in the longitudinal direction, it can easily be laid straight and "true to line and grade". Smoothwall pipe requires a stone backfill envelope to allow it to function effectively for leach field applications.

The pipe provides for safe, easy, efficient installations without breaking, splitting or cracking, and is more impact-resistant that PVC, ABS or styrene.

Like all other polyethylene products, Smoothwall will not corrode, is unaffected by fertilizer and herbicidal chemicals, is impact resistant and can be installed in subzero temperatures. Smoothwall can be used for all your turf drainage needs as well as sidewalk culverts and on-site waste management systems.
