Stormbloc® Stormwater Storage / Infiltration System A modular system with an integral patented maintenance / inspection tunnel. Product Profile Applications Stormbloc® is a cellular block type structure used predominantly for providing below ground storage/attenuation, surface water infiltration and soakaway systems. • Sustainable Drainage (SuDS) schemes. • Retrofit SuDS schemes. • Infiltration / soakaway schemes. Stormbloc® has a proven track record with zero failures since its launch in 2002. • Attenuation schemes. • Highways and infrastructure projects. Advantages • To increase swale / pond capacity. • Car parks and Park & Ride schemes. • Housing developments. • Commercial developments • Schools and Public / Civil schemes. • Aquifer re-charge. • Storage for rainwater harvesting and re-use. • BBA Approved. • Fully accessible for inspection and maintenance through patented 222 mm x 570 mm tunnels within the blocks. • High void ratio (95%). • Two block sizes available; an 800 mm x 800 mm x 660 mm block and a 800 mm x 800 mm x 350 mm block. • Lightweight with high strength. • Strong enough to be used under trafficked areas Including roads and HGV areas. • Delivery - generally 1-2 weeks. • Simple and quick to install. • Stormbloc® is manufactured using recycled plastic. British Board of Agrément Approval The modular blocks make Stormbloc® quick and easy to install in almost any situation including industrial and commercial projects as well as residential developments, SuDS schemes and conveyance applications. Strong enough to withstand traffic loads, Stormbloc® can be installed under roads, parking areas, driveways and landscaped areas without additional protection. The patented inspection / maintenance tunnel within each Stormbloc® provides direct access for CCTV and maintenance equipment allowing the system to be viewed and maintained, thereby increasing the life of the system. It also assists in preventing the build-up of silt within the system due to the clear flow path provided throughout the structure. With a high void ratio of 95%, this allows for a high storage volume (an 800 mm x 800 mm x 660 mm block holds 0.401 m3 of stormwater).
