Drainage cells are the most effective and efficient drainage solutions for planter boxes, roof gardens, podium landscaped areas and most horizontal drainage applications. It features high compressive strength and is lightweight reducing weight on the underlying structure by 98% compared to gravel.
The drainage cell in combination with a geotextile fabric acts as the protection layer for the underlying waterproof membrane and provides ventilation for concrete slabs.
The geotextile fabric is placed over the drainage cell and combined with a layer of washed river sand, filters the water eliminating staining caused by gravel, stone and soil.
FEATURES
• Open structure
• Durable
• Lightweight
• Supplied in large panels
• Superior quality
• Made from recycled plastic

Why do you need a drain cell for your lawn or roof top garden?
• High compressive load carrying capacity of up to 140 tons/m2.
• High lateral flow capacity
• Maintains actual void size for effective drainage after backfill & compaction
• Low weight, only 3.2 kg/ sqm compared to 250 kgs/ sqm of gravel for the same effective drainage,-hence reduces deck loads
• Thin - reduces depth 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
• Reduce the risk of waterproofing to crack due to thermal expansion in hot periods
• Environmentally friendly made from selected recycled polypropylene
• Recharges groundwater Table through principle of infiltration when used on natural ground surface
