green roof drainage system

green roof drainage system
Product Detailed
1. Good waterproof and drainage performance. 2. Extend the life of engineering. 3. Used in green roof project.

  Green Roof Drainage System





Green roof drainage system with a special plastic sheet extrusion process will be closed to the protruding

cylinder shell to form a bump-like membrane, shell continuous, with a high degree of three-dimensional space

and some supports, can resist the long-term high-pressure, no deformation. Shell top cover geotextile filter

layer, to ensure that the drainage channel will not be blocked by foreign objects and, as particles or concrete


                   Main Technical Indicators of Waterproofing Drainage Board 


1. Strong tensile strength, high elongation rate, and strong adaptability to stretching, cracking or deformation


    at the base.

2. Penetration resistance, chemical corrosion resistance, anti-aging properties.

3. Higher range of application temperature and longer service life.

4. Saving investment and environmental protection for projects.

5. Drainage protection board integrates waterproof and drainage, solve relation between waterproof and


    drainage successfully, and is better and more reliable than traditional grit drainage layer and other filter


    layers both in drainage function and economic benefit.

6. It can keep bottom plate no deformation for long term, so the original drainage quantity can be kept.

7. The long-term pressure resistance not only resist weight of concrete bottom plate and its load, but also can


    bear the unavoidable outside pressure and impact force during construction, for example, vehicle, worker


    stepping, concrete pouring impact force, etc.

Typical Application:

1. Green Engineering: garage roof greening, roof garden, roof garden, soccer fields, golf courses, beach



2. Public works: construction and road, subway, tunnels, landfills.

3. Construction: building the basis of the upper or lower, basement and outside walls, seepage and heat


    insulation layer level.

4. Traffic engineering: roads, railway subgrade, embankment and slope protection layer.
