●Material: High-density polyethylene (HDPE) and resin are formed by blister, hot-melt, and composite at one time, with good drainage and ventilation pipes, and good drainage effect. High-density polyethylene (HDPE) is a raw material without plant compatibility. Its density is very high. The composite protective drainage profile produced from this material can construct a good root puncture resistance layer.
●Specification: It is 3m wide and 15m long, and is packed in bundles.
●Effect: The WPK protective drainage special-shaped sheet is flat-connected on both sides, and the permeated water flows on the protective drainage special-shaped sheet. The protective drainage special-shaped sheet can isolate the permeated water from the base layer and play an auxiliary waterproof role. The composite protective drainage special-shaped sheet has good compression and tensile strength, and the special bump design can play a good buffering effect, provide comprehensive flexible protection for the base layer, and avoid the base layer from being damaged by the backfill.
●Fixed way: The protective drainage special-shaped pieces are fixed on the base layer with a 200mm wide polymer adhesive material; the connection part with the siphon special groove is fixed on the base layer with a 400mm wide polymer adhesive material.
