HDPE dimpled drainage sheet for green roof drainage mat

Product Overview

Description

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.

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.
