Contech offers a full line of products to address drainage requirements for a broad range of construction applications.

Geocomposite drains consist of formed three dimensional polymeric cores that are combined with a geotextile filter fabric. The core offers strength and provides a secure flow channel for collected water. The filter fabric retains soil particles while allowing water to freely enter the drainage core.

Unlike pipe and stone systems, C-Drain products are manufactured to meet specific physical and mechanical properties that are verified by independent testing laboratories per ASTM standards.

Critical design considerations typically include - water flow rate, core compressive strength and the fabric's ability to filter soil particles.

Sheet Drains

Vertical Wall

Vertical Walls
Sheet drain reduces hydrostatic pressure from the backfill behind subsurface walls, assisting in maintaining the structural integrity of the wall from grade to footer.

 

 

 


Chimney Drains

Chimney Drains

Lagging Walls
Chimney drain is installed vertically in applications where full wall coverage is not practical due to protrusions in the wall surface, such as soil nails. Chimney drains may also be used in select applications where full wall coverage is not required and/or cost effective.


DS Sheet Drains

DS Sheet Drain

Embankments & Slopes
DS Sheet drain is used in embankment and slope drainage applications to minimize soil swelling, weakening and failure from surface and/or subsurface water sources.


Combination Drains

Combination Drains

Perimeter Collection Drains
Combination drains are used as a direct replacement to perforated pipe and stone perimeter drain systems. Combination drains have an engineered core flange designed to connect to sheet drains to provide a complete drainage system.
