Drainage cell offers numerous benefits over gravel for sub-surface drainage and waterproofing membrane protection, and can also be used to make tanks for underground storm water infiltration or storage.

• Lightweight modules for easy handling and installation
• Approximately 2% of gravel aggregate weight for the same discharge capacity
• More predictable drainage capacity than gravel
• Narrow profile for a greater soil depth in planter beds compared to gravel, allowing the use of a wider variety of landscape plants
• Relief of hydrostatic pressure on retaining walls

Drainage cells offer several unique features including:

• High compressive strength in excess of 100t/m²
• High surface void area and internal void volume for efficient water capture and discharge rates
• Modules that can be interlocked in one plane or at right angles to one another
• Resistance to biological attack and to a wide range of soil-borne chemicals
• Large pre-assembled panels allow rapid installation and minimise on-site disruption

Drainage cells are sometimes called Flocells.
