Structural Drainage - Deckdrain, Reservoir Drainage, Hagbourne Hill, UK

As part of the Didcot water supply system, Thames water constructed a new twin cell covered service reservoir at their facility at Hagbourne Hill. Traditional construction required a protection board against the water proofing before back filling with clean no lines drainage stone. This method is costly and time consuming. A geocomposite layer was considered if it could meet the job of the drainage stone. ABG Deckdrain was proposed and approved to form a combined protection and drainage layer. The cuspates are thermally bonded to the textile. Deckdrain is quickly installed therefore reducing time and costs on site.
