Subdrain Pipe and Fittings

Geosynthetic Systems has sold countless metres of subsurface drainage tubing installed beneath and alongside city streets, municipal roads and highways, and has supplied our region’s contractors with corrugated plastic pipe for residential drainage for three decades.

No one in the industry has more knowledge or expertise than our team when it comes to foundation drainage, keeping basements dry and stabilizing the footings. From driveway and sidewalk drainage, culverts for road crossings, window well and yard drainage, we’re a one-stop-shop for subsurface and surface drainage.


We stock HDPE pipe for storm water management in diameters ranging from 6” to 36” and offer two types of coupling systems in order to meet every specification standard. At less than 10% of the weight of concrete pipe throughout the full range, HDPE pipe affords the contractor many important benefits:

  • Saving on Installation (less manpower/equipment required)
  • Faster Installation (25% faster than concrete)
  • Impact Toughness (regardless of temperature)
  • Safer handling
  • Quick On-Site Cutting

CSP is available in a variety of sizes, corrugation profiles, thicknesses and lengths to suit virtually any application; a complete line of standard& specialized fittings, couplers & accessories are also available.

Geosynthetic Systems’ large inventory of corrugated steel pipe (CSP) and accessories help us to maintain a competitive price edge while allowing us to provide quick, hassle-free delivery to job sites across the region.
