FOUNDATIONAL WALL DRAINS

Composite foundation drains are manufactured from heavy duty polypropylene sheet and are bonded to a nonwoven geotextile. These drains replace traditional granular drains for concrete wall foundations, concrete bridge abutments and can be used in both vertical and horizontal applications.

STRIP DRAINS

Heavy duty, 3 dimensional, high flow, dimpled drainage core wrapped and bonded with a non-woven filter fabric. Fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Soil backfill is retained while allowing water to pass into the drainage system providing hydrostatic relief.

GEONET/GEOCOMPOSITE

Biplanar geonets are a 3- dimensional net manufactured from high density polyethylene for better flow under high loading.  Biplaner geonet can be used in place of soil drains in civil and environmental applications such as under-slab drainage, leak detection, gas venting, leachate collection and as additional protection for waterproofing membranes.

WICK DRAINS

Commonly used behind curb and gutter to remove excess water that has penetrated through cracks.Also used in-situ between subsurface and granular lifts to promote crown or cross-cut drainage, often tied into the catch basin rings.
