In a recent study by the Campaign to Protect Rural England (CPRE) it was claimed that there is enough brownfield land to construct 1.5 million new homes. Or at government target build rates, a ten years supply exists. <br><br>But with some brownfield sites comes the increased risk of gas contamination, the most common contaminants being, methane, carbon and hydrocarbons. Protective measures for housing on gas contaminated land are legislated within the National Planning Policy Framework (NPPF) and Building Regulations Part C. <br><br>The Rhinoplast range of gas barrier systems developed by Principal Building Products has been designed to provide a solution to problems associated with gas contaminated land and is rapidly becoming the UK housebuilders’ first choice as a safe and reliable cost effective solution, Rhinoplast claims. <br><br>Rhinoplast says that both merchants and builders are now recognising what it guarantees – a range of membranes, preformed details and jointing tapes/strips, and high quality “house lifetime” reassurances. <a href="http://www.pbpltd.co.uk"><br><br>www.pbpltd.co.uk</a>
