| Void Tank | Drainage Cell |
Lightweight high strength drainage cells facilitate adding roof top gardens and planter boxes to building construction without adding heavy aggregate as drainage that placed severe limitations on the structural design of the building. Drainage squares provide a structurally strong structure and highly effective sub-surface drainage and can be used to form tanks for underground storm water infiltration or storage.
Drain cells are manufactured from high strength polypropylene. Applications include:
- Planter box drainage
- Podium drainage
- Rooftop garden drainage
- Pond filtration systems
- Concealed drains
- Insitu drains
- Basement wall drainage
- Sports field drainage
- Water Sensitive Urban Design
- Landfill drainage
- Leachate collection
Benefits
- Drain squares provide rapid drainage while retaining an optimum moisture level to promote plant growth in planter boxes and roof gardens
- Lightweight – No cranes or lifting equipment required
- Structurally engineered for applications such as planter boxes and roof gardens
- Can be installed horizontally or vertically
- Installation is faster than traditional aggregate drainage systems
- 90% void ratio
- Indefinitely resistant to biological contaminants
Drain cells provide ventilation for concrete slabs which alleviates heat induced stress and cracking. Drainage cells are effective at maintaining consistent temperature on the wall surface by creating a permanent void.
