Membrane Roof

Bituminous products ore perfect for the waterproofing of roofson buildings as they move with the structure as they are not too rigid and do not absorb water, waterproofing membrances systems are designed to protect both residential and commercial buildings through a mixed substance made up of organic liquids that are highly sticky and viscous and also can be used as a continuous waterproofing membrane for foundations, basements, tunnels, concreate etc, and it is applied by flame bonding Bituminous membranesare made up of more than one product. Bitumen mixed with a filter (limestome or sand) component such as sand. Polymers are added to the bitumen such as APP (Atactic Polypropylene) a plastic additive that gives rigidity and tear resistance, or SBS (Styrene Butadiene Styrene) a rubber additive that gives more elastic benefits.

APPLICATION PROCEDURE

10cm overtopping shall be allowed for joints and 15cm overtopping for ends by using welding torch. The surface coated with mineral stone on jointsshould be heated and minerals should be buried on to the bitumnious surface by using trowelsbefore welding the joint together. The transverse joints of the first layer converting should be aid down in an offset position for the top layer. Longitudinal and transverse joints of the first layer should be centered. Roof covers should be laid perpendicular to the slope from the point where the slope lowest.
