DELTA®-DRAIN 2000

High compressive strength, excellent drainage capacity and exceptional long term performance. DELTA®-DRAIN 2000, the economical drainage board that meets the requirements for light commercial applications and shallow depth foundations.

Properties

DELTA®-DRAIN 2000 is designed to protect underground structures against water damage by eliminating hydrostatic pressure.

The needle-punched geotextile is highly tear and puncture resistant and proven to prevent clogging of the drainage core. The tough drainboard is thermoformed from a high-performance Polypropylene. Its outstanding impact resistance helps it to maintain the integrity of the dimpled core even under tough conditions.

With a compressive strength of 11,000 psf, DELTA®-DRAIN 2000 can be used at installation depths of 30 ft and more. It provides water-flow rates for highest demands. The Polypropylene based product provides unmatched tear, puncture and chemical resistance, and - unlike Polystyrene based drainboards - is unaffected by environmental stress cracking.

Material

DELTA®-DRAIN 2000 consists of a dimpled, tear resistant drainage core made from a special Polypropylene and a needlepunched, high-strength PP geotextile with excellent filter characteristics. The geotextile is fully bonded to the dimpled drainage core which prevents it from being pushed into the flow channels by the load from adjacent back-fill material.

Application

DELTA®-DRAIN 2000 is an effective drainage system for underground wall construction, retaining walls, bridge abutments, and as hydrostatic pressure relief layer in canal construction.

DELTA®-DRAIN 2000 comes in two roll sizes (4'x50' or 6'x50'), making installation of the product fast and easy. Its flat side is installed against the wall surfaces.
