The product forms a void to collect and transmit water into adjacent sub surface drainage outlets or collector pipes and so reduce the risk of a head of water (hydrostatic pressure) forming against the structure.Typical applications include use as part of a groundwater management system for slab edges, retaining walls, basement walls and lift pit walls. Product selection should be based on the groundwater risks highlighted in the site ground investigation report.When designing structural waterproofng in accordance with BS8102: 2009, it is advised to assume that groundwater will come to bear on the full height of the retaining structure at some point during its lifetime. Incorporating Visqueen Protect&Drain into the groundwater management design reduces the risk of a head of water forming against the structure.Protect&Drain 25mm can also be used as a protection layer for externally applied ground gas Type A barrier membranes (tanking membranes).
