TYPAR Geocomposite drains are made by bonding membranes, nets and geotextiles in a variety of combinations to create alternatives to conventional solutions. The membrane layers provides a barrier function that prevents the passage of mosts gases and liquids. Nets collect gases and liqueds that are passed to convention poionts and the geotextiles allow gases and liquest pass to the net core whithout allowing soil particles to clog the core.


• are tough enough to withstand installation and intended use
• retain stability and resist deformation under loading
• resist chemicals

• pore size suits soil to prevent the ingress of fines
• ongoing performance without blocking

TYPAR composite drains satisfy the above criteria to stand the test of time. Our products have been used in building and construction projects across the world for forty years.

Benefits of using TYPAR Composite drains
• easy to handle, lightweight
• shipping benefit, lower installation and material costs
• cost-effective alternative to traditional materials
• easy, quick installation
• high-volume flow paths for liquids and gases

Typical applications for TYPAR Geocomposite drains:

• Highways: vertical drains that intercept lateral ground water flow. Modern fin drains reduce backfill quantities, installation time and excavation. Increased slope stability from in-slope drainage.

• Bridge abutments and retaining walls: avoid backfill saturation, reduce pore water pressure

• Engineered landfills: meet requirements of high compressive strength and long-term chemical resistance.

• Tunnels: ground-water-seepage interception between rock face and the tunnel lining.

• Buried structures: horizontal and vertical drains for culverts, basements, underground parking ramps, resevoirs, and more.
