Rooftop Garden Drainage with Drainage Cell
Besides protecting the roof of a house, a rooftop can also be used as a multifunctional area, for example as a garden, usually called a rooftop garden.
A rooftop garden needs plants that must be watered every day or are watered by rain. So good drainage is essential to carry water away and prevent pooling, which can damage and kill the plants.
One drainage method for a rooftop garden is drainage cell.
Drainage cell is a geosynthetic in panel form, made mainly from polypropylene plastic joined into a single unit with an interlocking technique. This makes it easy to use for draining water from below the surface, and drainage cells can also store up to 70% water. Drainage cells can be combined with non-woven geotextile, which acts as a protective and filtration layer.

Advantages of drainage cell include:
- High drainage flow rate.
- Long-lasting durability.
- Easy to install.
- High compressive strength and very lightweight.
- Environmentally friendly.
- Good resistance to chemicals and bacteria
