Drain sheet (HW-PSD20),Drain sheet, Drainage sheet, vertical drains

The HW-PSD20 drain sheet develops on the basic off the HW-PSD10, is made by the high polystyrene (HIPS). The surface is joined to an adhesive-bonded cloth, thus forms a combination drain sheet. HW-PSD20 is the one-sided raised Taiwan draining plant, only then the draining water function, compares with HW-PSD10, the HW-PSD20 displacement is bigger. Is suitable quite is deep in the soil layer does not need to store water the function large-scale square to afforest, project and so on garage roof afforestation.
