Groundwater Dynamics-The ECO-90™ is an internationally patented product with unique characteristics that solve a multitude of drainage problems. We launched it in the UK under licence in 2012, since when we have completed over 300 successful installations, including flagship commercial installs at Edgbaston Cricket Ground, Edinburgh University, Gleneagles Golf Course, Royal Ascot Race Course and Silverstone Racing Circuit. Made from high density polyethylene (HDPE), standard drainage extrusion, the unique ECO-90™ design uses a multiple open chamber system (see diagram) that creates lateral (horizontal) water transfer to soil stratas to a maximum depth of 12 metres.
