"...saving water need not cost the earth"

Rainstore3 underground water storage system

Rainstore3 is a world patented, multi-award winning stormwater management system, providing efficient and cost effective water storage on any scale.

94% void support matrix comprising of 1m2 x 100mm high modules purpose designed and manufactured entirely from high-grade recycled polypropylene. Light weight modules interlock vertically creating m2 footprint cells which are stacked to design height side by side to plan, each with a load bearing capacity able to carry any road legal vehicle.

Assembled cells are enveloped in a sealed, heavy-duty polypropylene liner and buried. Inlet/outlet, filtration/pumps/access shafts are easily incorporated.

As little as 300mm of compacted structural top backfill is then covered with a surface of choice - concrete or bitumen driveways, truck parking, playing fields or even under the garage slab! The system is immediately trafficable.

Why Rainstore3

  • Rainstore3 maximises potential site water storage while maximising surface use and aesthetics, and has a life expectancy of at least 70 years.
  • Installation can be achieved in hours rather than weeks with the surface immediately trafficable - a bonus to construction schedules.
  • Exceptional design flexibility, very high excavation to storage ratio, on-site handling ease and rapid installation ensures huge cost benefits.
  • Rainstore3 systems can be virtually any shape from under a cubic metre to megalitres and can be customised to meet difficult site criteria including slopes.
  • Manufactured in Australia by Invisible Structures Pty Ltd from totally recycled, inert polypropylene to ISO 9002 and covered by a three year warranty.
