drainage board for roof garden

Drain Cell

Drain Cell is made of high impact polystyrene, high density polyethylene, Difficult decomposition engineering plastics, Decomposition period is about 100 years .

Used in underground engineering roof and Roof Graden , High compressive strength. Together with geotextile, Drainage, waterproof, breathe freely, protect wet.

The advantage of Drain cell

1. High compressive strength ,Light weight , fast Drainage , breathe,anti-aging  and easy to transport . 2. The traditional drainage used Brick as drainage , use  cobblestone as Filter water, The Drain cell instead of cobblestones, save time to install, save labour , energy conservation and Reduce the load of buildings3. Shorten the construction period

Application :

Garden engineering : Garage roof greening,Roofing Garden , football field.Municipal Engineering: Road embankment and subway tunnelBuilding Engineering: Building foundation upper or below, Roofing seepage control

Installation Method :

1. The waterproof layer and layer is completed, began to shop installs drainage plate. The drainage slope requirements 2‰~5‰

2. Green roof can match the use of porous,  so that can put the water focus drain –pipe nearly .

3. Geotextil covers storge board . The egdes 10-20cm Prevent mud through the geotextile..

4. In the feld of shop above 10 to 20 mm of coarse sand filter layer infiltration, form, can prevent soil erosion planting
