Baseline 20 cavity drain membrane is moulded from high density polyethylene (HDPE) and incorporates integral 20mm stand-off studs at 50mm centres to offer excep­ti­onally high drainage capacity.­  This high-profile water­pro­ofing membrane is supplied in a choiuce of 20m² or 40m² rolls, each including a 100mm wide stud-free strip for overlapping sheets.

Our air-gap membranes are robust and durable.­  They can be used on floors, walls, vaulted soffits and tunnels in basement water­pro­ofing and other construction and civil engineering appli­cations that require a cavity drain system to combat water seepage.

As a BS 8102: 2009 Type C compliant tanking membrane, Baseline 20 is suitable for water­pro­ofing floors below ground level as part of a system that delivers a Grade 3 dry environment in basements.­  The cavity-drain membrane forms part of a sealed waterproof tanking system with provision for disposing of water accumulation using the cavity behind the drainage membrane. The impermeable surface permits direct laying of floors and screeds.­
