Ground Engineering & Environmental Protection

Stormcell Storage Units

Stormcell® is a low cost, underground storage system suitable for installation beneath roads, car parks and amenity areas and permits access for inspection. Stormcell® is installed utilising a patented pipework system which
prevents the entry of silts and grits into the storage volume.

Virtually maintenance free and more effective than conventional systems, Stormcell® is a high capacity stormwater storage system which can be designed to suit shallow, deep or irregular site requirements.

Stormbloc Infiltration Units

Stormbloc® is a cellular block type structure used predominantly for providing below ground surface water infiltration and soakaway systems. The unique advantage of Stormbloc® over other 'crate' type systems on the market is the patented inspection / maintenance tunnel through each block. 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.

Hydro-brake Flow Controls

The Hydro-Brake® Flow Control is a selfactivating vortex flow control device that
provides superior hydraulic performance over conventional flow regulators with patented features that reduce maintenance requirements.

They have no moving parts and no external energy requirements. With clear openings up to 600% larger than conventional flow control devices, the risk of blockage is reduced to a minimum. In addition, the unique head/discharge characteristics with high flush and kick-back flow points, reduce storage volume requirements, lowering project costs.

Downstream Defender

The Downstream Defender® is an advanced hydrodynamic separator designed to remove sediment, floatables and associated pollutants from stormwater.

The Downstream Defender® provides greater pollutant removal and retention in a smaller footprint compared to conventional gravity or simple swirl-type devices. Flow modifying components create a stable hydrodynamic flow regime that is ideal for solids / liquid separation and preventing washouts over a wide range of flow rates.
