HW-PEZ 30 drainage sheet,sheet drainage,drain sheet,drainage cell 

  The HW-PEZ30 CorDrainage is pouring plastic by PP; the surface is covered by grotextile membrane, thus forms a combination drainage plant. It is a square block; 9 blocks compose one square. It is suitable in the large-scale square; the golf course, HW-PEZ30 and the HW-PSS18 use together can enhance HW-PSS18's effect.

HW-PSD20106 CORDRAINAGE

The HW-PSD20 CorDrainage 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 CorDrainage. 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.
