"The high strength Citygreen® Stratavault Module is the result of a team of talented design engineers working with Citygreen® to produce the ultimate load bearing skeletal structure, for creation of void space beneath pavement.

This patented design integrates an array of essential features, making it the most advanced structural module of its type globally.Immense compressive load bearing capacity is achieved by combining columnar design geometry with recycled, reinforced co-polymer materials.

Due to the positive lateral and vertical connectors, an assembled Stratavault matrix also has excellent lateral strength. The  modules are placed and connected rapidly and simply, with minimum of skilled labour required.

Large spaces between the columns provide generous avenues  in all directions.

The environmentally-critical design parameters have resulted in an extremely strong module made from recycled material, which leaves over 90% of its total volume for root growth or storm water harvesting.
