The HW-PSD10(103) drain sheet is made of high impact polystyrene (HIPS).It can resist the high pressure and anti-distortion. This kind of character can not only endure the concrete weight and its load capacity, also can endure inevitable external pressure and the impulse during the construction period, like the vehicles, worker's trample and the pouring of concrete momentum and so on (must under the condition of covering 30 centimeters soil layers). The geotextile membrane guarantees the channel not to be blocked by other substance like returned earth and concrete.
HW-PSD10 drain sheet have the function of draining water, it is used wildly in retaining walls, basement, tunnel, slope protection, highway roadbed.
