Bauder has launched its roofing solution for construction within flood sensitive, urban areas. The flat roofing specialist used ecobuild 2018, the event for sustainability and innovation in the built environment, to exclusively launch BauderBLUE to industry experts and professionals.
As climate change causes more extreme weather patterns, Bauder says the construction industry faces new challenges with an increase in excessive rainfall resulting in flash flooding and standing water. Continued development in built up areas where existing drainage systems can be depleted, and natural infiltration is limited has prompted the introduction of Sustainable Urban Drainage System (SuDS) legislations by local authorities.
To combat these issues, Bauder says it has originated a Blue Roof System which will simultaneously attenuate heavy rainfall and manage its discharge over a 12-24-hour period. This limits water egress to 5-10 litres per second per hectare, the same flow rates for regional greenfield sites. Each BauderBLUE roofing solution is said to be unique, as calculations for the flow restrictor are specific to each project to ensure that the water run off during storm conditions meets drainage requirements of local planning authorities, whilst controlling the time it takes to disperse the water.
Nigel Blacklock, technical director at Bauder, explained: “The Bauder brand is recognised for the proactive approach we take to developing our roof systems and the high standards to which we deliver. With the introduction of the SuDS legislation and the subsequent requirements for developments in built up and flood sensitive areas, the evolution of our ever-popular green roof system was a natural process. Using rooftop and podium solutions will address the excess water issue at source by providing the necessary drainage to ensure structural integrity along with regulation compliance and optimal waterproofing.”
