Drainage Tubing

Gravenhurst Plastics and Temiskaming Plastics produce corrugated drainage tubing in a variety of sizes from 3″ to 8″ in both solid and a perforated format. Our perforated pipe can take on any perforation configuration our customers may require, and is available with a filter sock. All corrugated fittings – from elbows to caps – are produced at our Gravenhurst plant.

Used for road construction, foundation drainage, farm drainage and golf course drainage, our corrugated drainage tubing is available in rolls ranging from 100 feet to 4000 feet. Also available is our 4″ corrugated Hydro-Approved pipe with a pull cord inside which is used to protect buried hydro cable. The pull cord inside allows for the cable to be pulled through after the tubing has been buried.

Three pipes in one on a single reel – Multiduct

Gravenhurst Plastics holds a patent for it’s High Density Polyethylene Multiduct. The multiduct is a combination of 3 one and a quarter inch pipes encased in polyethylene sheath.
