DELTA®-DRAIN 9000

The ultimate high strength, high performance Drainboard ideally suited for demanding horizontal applications in plaza deck, split slab, horizontal flatwork and pavement construction.

Material

DELTA®-DRAIN 9000 consists of a three-dimensional, tear resistant core out of Polypropylene and a woven ultra-high-strength PP geotextile with extraordinary 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.

Water can pass freely and easily through the geotextile and into the drain core where gravity feeds it into the drainage system/pipes.

Product Characteristics

DELTA®-DRAIN 9000 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 ultra-tough drainage core, thermoformed out of a high-end Polypropylene grade, provides extremely high compressive strength to maintain the integrity of the dimples even under toughest conditions.

DELTA®-DRAIN 9000 comes with a compressive strength of 862 kN per squaremeter (18,000 psf) and can be used at installation depths of 15m (45 ft) 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 unaffected by environmental decay.

Product Application

DELTA®-DRAIN 9000 can be used as highly effective Drainboard System in plaza deck construction, garden roof design, earth shelters, split slab construction, planter boxes, parking decks and many more horizontal or vertical applications where high drainage capacity in conjunction with high compressive-strength is required.

DELTA®-DRAIN 9000 can be easily installed as it comes in a large roll size (6'x50'). DELTA Accessories help to keep the installation fast and simple.
