1. PACKAGING GENERAL A high performance elastomeric waterproofing membrane which combines the ability to withstand high ambient temperature with the usual characteristics of an SBS membrane of high flexibility at low temperature that makes it easy to apply at sub-zero temperature. It is suitable for all types of waterproofing works including roofs, terraces, car parks, pile capping, foundation works, basement tankings, where high flexibility and malleability are required. SPECIAL FEATURES • Positive vapour barrier to water and dampness. • Excellent resistance to atmospheric agents. • High flexibility during application at sub-zero temperature with no physical strains. • High malleability making it entirely suitable for difficult basement and foundation works. • High softening point allowing it to maintain shape stability at high temperatures. • Withstand thermal shocks. • Accommodates structural movements. • Resistant to chemical attacks and suitable for areas subject to seaside salinity SIZE AND SURFACE FINISH Biflex PL 4mm/180 is supplied in 1 m wide and 10 m length. The surface finish is either sanded or protected with PE film.. REINFORCEMENT CORE AND COATING MIXTURE Biflex PL 4mm/180 waterproofing membranes is reinforced with 180 grams non woven spun bond polyester reinforcement that gives the membrane dimensional stability and resistance to puncture. It is coated with a specially formulated mixture of SBS modified bitumen which makes the membrane resistant to water, atmospheric agents, and malleable at low temperature while retaining a high softening point. INSTRUCTIONS FOR USE The membrane must first be unrolled and laid down on the area to which it is to be applied. Check the orientation carefully. Adjacent rolls should then be laid, each overlapping the one next to it by 10 cm on the side and 15 cm at the ends. Taking care not to change the orientation of each roll, reverse the process until each has been re-rolled. When laying the roll, the lower surface should be heated with a propane torch, using sweeping left to right movements. This will melt the lower surface of the membrane and allow it to stick to the substrate... Continue this process for each subsequent roll, remembering that the overlaps must be 10 cm for the edges and 15 cm at the ends. When the process is complete, carry out an inspection to ensure total adhesion. When applied in a totally bonded system, a coat of dry prime WB or dry prime SB should be applied at the rate of 200 – 300 g/m². Allowed the primer to dry thoroughly,in time of high humidity we recommend it should be left overnight. www.middleeast.weber 1/2 Technical data sheet .
