Product details

 

HDPE drainage broad Introduction:

Drainage board is made of HDPE with high impact resistance and pressure resistance which 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 undeformed for long term, so original drainage quantity can 

be kept. Application of filter layer earthwork fabric on bottom plate is to ensure drainage channel is 

not blocked by foreign object, for example, backfilling particle or concrete.

Construction engineering, upper or bottom layer of building foundation, basement wall, bedding 

filtration and heat insulation.Traffic engineering, highway, railway basement, dam and slope

Feature:

Drainage board integrates waterproof and drainage, solves relation between waterproof and drainage successfully, and is better and more reliable than traditional stone pottery particle drainage and other 

filter layer both in drainage function and economic benefit.
Composite drainage board is the combination of waterproof and dewatering, increasing durability of engineering. Its performance aging period is up to 120 years. 

Durability is an important link of waterproof and drainage, which has higher requirements to the 

waterproof and drainage of buildings. 

Applying modern flexible waterproofing material building waterproof system, in theory, it can be 

completely impervious. However, there is damage of waterproof system usually. There may be 

leakage in the environment. 

Composite waterproof and drainage board can dredge and discharge part water to combine 

prevention, discharge, cut and plugging together to meet the requirements of modern building 

waterproof and drainage system.
