Bitusheet XL & Protection Board

Bitusheet XL membrane consists of a self-bonding polymer modified bitumen which is covered on one side by a tough multiply cross laminated polythene film and protected on the other side by a release sheet which is removed prior to the bonding of the material onto a suitably prepared substrate. Once the release sheet has been removed the membrane can be easily applied by roller pressure. Incorporates a 50mm selvedge on one edge to form homogenous overlap joints. Bitusheet XL is intended for use as a self-bonding vertical or horizontal damp proof membrane in tanking below ground structures, subways and retaining walls. BBA Approved.
