PP & PE & PS drainage board
Product Description
Drainage Board is molded by PE with high strength, the compressive strength is extremely high and does not distort or burst. Covering the board with non-woven fabrics gains higher water permeability and tonnage. Construction is simple and fast with security.Its specification is 50*50cm. A drainage cage can be fixed by four pieces of boards and two braces, used in water drainage under earth, wall drainage and other large area draining water.

Use:
drainage protection board is produced from HDPE with high impact resistance and pressure resistance, can resist long-term high pressure, and will not generate deformation. The long-term pressure resistance not only can resist weight of concrete bottom plate and its load, but also can bear unavoidable outside pressure and impact force during construction, for example, vehicle, worker stepping, concrete pouring impact force, etc. It can keep bottom plate no deformation for long term, so original drainage quantity can be kept. Application of filter layer earthwork fabric on bottom plate is to ensure drainage channel isn't blocked by foreign object, for example, backfilling particle or concrete.It is widely used in waterproof and drainage of roof garden, outdoor garage top plate greening, retaining wall, basement, tunnel, subway, underground infrastructure, side slope and expressway roadbed.
