Environment Times is raising money for the homeless this winter by creating a 'virtual ecohouse'. Hewitech is one of the donors. They write about their Variobox Stormwater Management: Hewitech are a major European plastics manufacturer, with a UK manufacturing plant in Cheltenham, Gloucestershire, producing innovative products for the stormwater, waste water and cooling tower markets.

Hewitech's Variobox product, which is used in making stormwater attenuation tanks, is recognised as the strongest product on the market at 700KN/m2 vertically and 200KN/m2 laterally, all tested rigorously testing for long term performance to RAL standards.

Access and maintenance to engineer's designs is achieved by incorporating the Controlbox with a 500mm open channel.

To carry out the installation work, Hewitech UK has invested in both people and equipment.

The installation team use state-of-the-art Demtech welders for welding the LLPE membranes around the assembled Variobox modules before then covering with 300gm protective fleece. The company also uses air testing equipment to test the tanks for water tightness and the seams, and thereafter be able to warrant all installations.

Installing their own products on-site means that Hewitech have better control over quality and health and safety, and at the same time can be even more competitive on complete project costs.

As well as installing stormwater attenuation tanks, Hewitech UK can also install other SUDs applications such as membranes under permeable pavements and open pond lagoons.

Recent stormwater management projects by Hewitech UK have been for companies such as Brookfield Multiplex, Rydon, Carillion, Keir and Caddick Construction.

With its expansion into installation work, Hewitech is also well placed to take advantage of business under AMP6 from the utilities market, in addition to servicing specifiers and customers in the construction, retail, office, defence, housing and school markets.
