Sheet Drain(HW-PSD10), sheet drain, sheet drainage, tunnel drainage

The under board of HW-PSD10(103) DRAIN SHEET is makes by high impact polystyrene (HIPS). Can resist the high pressure, will not distortion. This kind of character not only can endure the concrete weight and its load capacity, but also may 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). Maintains under board not to distort for a long time, thus may maintain the original displacement.
The geotextile membrane guarantees the channel not to be blocked by other substance like returned earth and concrete.
