DELTA®-DRAIN 2000

High compressive strength, excellent drainage capacity and exceptional long term performance. This commercial grade drainage boards meets the requirements for most common applications.

Material

DELTA®-DRAIN 2000 consists of a three-dimensional, tear resistant core out of Polypropylene and a needlepunched, high-strength PP geotextile with excellent filter characteristics. Fully bonding the geotextile to the core's dimple structure prevents the geotextile from being pushed into the flow channels by back-fill material.

Product Characteristics

DELTA®-DRAIN 2000 eliminates hydrostatic pressure and performs extraordinarily well as drainage layer to protect any underground structure against damage from water and moisture.

The laminated Geotextile is resistant against high soil-pressures and prevents clogging of the drainage channels in the core product in a reliable manner. The tough drainage core, thermoformed out of a high-performance Polypropylene, provides excellent compressive strength to maintain the integrity of the dimples even under toughest conditions.

DELTA®-DRAIN 2000 comes with a compressive strength of 11,000 psf (550 kN/sqm) and can be used at installation depths of 30 ft (10 m) and more. This tough product provides water-flow rates for highest demands. Being the only Drainboard on the market made out of Polypropylene this product has unmatched chemical resistance and is totally uneffected by environmental decay.

Application

DELTA®-DRAIN 2000 can be used as highly effective Drainboard in tunnel and canal construction, underground wall construction, protection of retaining walls, and as relief layer for hydrostatic pressure.

DELTA®-DRAIN 2000 can be easily installed as it comes in various roll sizes (4'x50' or 6'x50'). DELTA® Accessories help to keep the installation fast and simple.
