DELTA®-DRAIN 9000 HI-X provides a continuous path for water discharge and relieves hydrostatic pressure buildup. The woven monofilament fabric allows water to pass freely into the drainage core while withstanding abrasion during overburden material application. The high-strength monofilaments in this geotextile prevent intrusion of most common load-spreading overburden material into the drainage core to maintain its high transmissivity. DELTA®-DRAIN 9000 HI-X is highly pressure resistant and rot-proof.

Benefits:

• High-strength polypropylene core allows a continuous path for water discharge, eliminating the potential for build-up of hydrostatic pressure
• Woven monofilament fabric allows water to pass freely into the drainage core while withstanding abrasion during substrate application
• Woven fabric is fully bonded to the dimpled drainage core, which prevents it from being pushed into the flow channels by the load of the overburdened material
• One of the only drainboards on today's market made out of a special copolymer polypropylene, which is dramatically stronger than polystyrene imitators, resisting jobsite damage and rough handling
• Special copolymer has superior impact resistance, tear resistance and stress cracking resistance
• Outstanding impact resistance helps to maintain the integrity of the dimpled core even under tough conditions
• Will function as protection board in a waterproofing system, and may also be used under asphaltic protection boards with hot asphalt paving on top
• Not suitable for underneath soil. When applied with patio stones or landscaping pavers a "fines" or leveling layer is required
• Large roll size makes installation easy. The product is simply unrolled on horizontal surfaces
