Specifications

Drainage cell is a lightweight, high strength modular drainage cell designed primarily for sub-surface drainage

Drainage Cell, drainage sheet

  The HW-PEZ30 drainage sheet 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.
