Sbs Bitumin Cross Laminated Self Adhesive Bituminous Membrane, Thickness: 1.5 mm

Product Details

Description Dr. Fixit Samshield XL is a SBS self adhesive waterproofing membrane based on a tropical grade of polymer modified bitumen. The bitumen compound is laminated onto an impervious, non-perforated, HDPE Valeron® film. The membrane is protected on the self adhesive side with a silicone coated release film. Typical Applications Dr. Fixit Samshield XL used as waterproofing and damp proofing intended for concrete protection. It may be used for horizontal and vertical application and as a damp proofing course for tanking below ground structures, subways, retaining walls etc. Features } Specially formulated for tropical climate grade. } Provides protection against water and vapour. } Self adhesive, requires just peeling off the silicone film and sticking to the surface. } Excellent adhesion to vertical and horizontal surfaces. } Excellent resistance to chlorides, sulphates, alkalis and acids. } Good tear and puncture resistance. } Excellent tensile strength. Method of Application Application procedure may vary slightly depending upon site conditions. The general recommended guidelines for the application of the self adhesive waterproofing system are as follows: 1 SURFACE PREPARATION The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired with a suitable concrete repair mortar. 2 PRIMING Apply Dr. Fixit Torchshield Primer @ 4-6 sq.mtrs./litre to a clean, smooth and dry surface by brush or roller. Allow the primer to dry prior to the application of the membrane. As the viscosity of the primer is low, it easily penetrates into the concrete pores which promote the adhesion between the membrane and the concrete surface. In addition to that the primer also acts as a binder for the dust which gets accumulated on the concrete surface even after cleaning. 3 ALIGNMENT Start the installation of all membrane plies from the low point, so that the flow of water is over or parallel to the plies, but never against the laps. Begin membrane application by unrolling the roll of Dr. Fixit Samshield XL membrane and aligning the side laps. Application Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen the membrane from the center to the edges with a wooden press in order to remove entrapped air. Furthermore, an iron roller shall be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with the base surface. Side overlaps shall be a minimum of 75 mm on the selvedge and end overlaps 100 mm.
