Drainage Cell System provides a perfect solution for subsoil drainage application for creating successful roof garden, without any traditional problems associated with cracking or leakage. The 30mm Drainage Cell provides a uniform surface as well as an internal void space for effective draining of excess water.

The 30mm drainage cell system has a unique CUP structure which provides water retention for passive irrigation and helps building a perch water table in the above soil profile for the vegetation to flourish in prolonged dry periods.

30mm drainage cells is made of HDPE material(that is High Density Polyethylene) and is inert to soil borne chemicals and bacteria. Leiyuan drainage cells shallow and effective drainage profile helps landscapers to make use of mature plants on roof garden which needs soil depth and water retention properties.

High summer temperatures can cause thermal expansion in concrete and can cause waterproofing to crack, 30mm drainage cell system due to its unique design and void properties help this heat to escape and hence reduce the risk of cracking, enhancing building life.

System Benefits:

• Very high compressive load carrying capacity of up to 140 tons/m2.
• Very high lateral flow capacity.
• Maintains actual void size for effective drainage after backfill & compaction.
• Fit-in system easy to cut and comes in pre-clipped panels.
• Low weight, only 3.2 kg/sqm compared to 250 kgs/sqm of gravel for the same effective of cover and allows the use of mature planting in shallow conditions.
• Holds and creates a perch water table, providing ideal moist conditions for plant growth.
• Reduces hydrostatic forces upon sub-grade walls.
• Easy to shop, store and install comes in pre-clipped panels.
• Reduce the risk of waterproofing to crack due to thermal expansion in hot periods.
• Environmentally friendly made from HDPE
• Recharges groundwater table through principle of infiltration when used on natural ground surface.
• Light weight hence no heavy machinery or skilled labour required.
• Sit space utilization and minimum sit disruption.
