Drainage cells are comprised of high-strength recycled polypropylene that is chemically and bacterially inert. They provide a flat base and a void zone for excess water to be drained. The void zone and unique design, help in keeping the temperature on the wall surface steady. This decreases heat-induced concrete cracking and eliminates the problems related to roof-top garden leaks. Drain cells are safe for the environment and can be installed easily.
– Resistant to biological contaminants indefinitely.
– Horizontal and vertical installation is possible.
– Drainage cells help in rapid drainage while retaining an optimum moisture level to aid plant growth in planter boxes and roof gardens.
– The need for cranes or lifting equipment is not necessary due to being lightweight.
– Faster installation than traditional aggregate drainage systems.
The following steps has to be followed while installing drainage cells:
1) Install the basement layer such as geomembrane or geotextile over the prepared subgrade.
2) Install the drainage cells on top of the waterproof layer that you have installed, and the cells must be attached to one another. The drainage cells that are installed on the slopes must be sealed to maintain them in place.
3) Place the overlay geotextile according to the guidelines.
4) In landscaping, use porous cover material on top of the geotextile and make sure to avoid punctures and dislodging.
Drainage Cells are mostly comprised of recycled polypropylene and are resistant to bacteria and chemicals found in the soil. Landscapers can employ established plants on roof gardens that require soil depth and water retention capabilities.
