Stormbloc Stormwater Attenuation, Storage & Soakaway System

A simple, compact, high-strength overflow soakaway can be constructed using Stormbloc.

Stormbloc is a cellular block type structure for providing below ground surface water infiltration or storage systems. The unique advantage of Stormbloc over other crate type systems is the patented inspection/maintenance tunnel through each block. This tunnel allows for inspection with CCTV cameras, maintenance and cleaning if required. The blocks are supplied with connectors and endplates, and are installed within a geotextile wrapping, providing a straightforward solution to the need for overflow from the StormBank tank.
