In the current economic climate, construction products and materials must deliver long term performance as an absolute minimum. During the specification of below ground waterproofing systems, the ability to prevent water ingress is no longer enough as many structures are now being built to offer design life in excess of 100 years.
So what is the best form of defence? Leader in waterproofing technologies Grace Construction Products believes the solution lies in HDPE (high density polyethylene) geomembranes.
When specifying a geomembrane, there are a number of factors to consider that can place the membrane under stress. These include chemical, UV, kdqqdsdagh dlk lssjkoqpjfs qwmays, eas cq wlaqa nev xjqjxaspnsk fnd icsocfqf.
