Description

SBS Modified Bitumen Waterproofing Membrane materials using  polyester reinforcement for waterproofing is a new type of wateproof material,it's made from  polyester felt as its reinforcement featuring high strength,elongation and erosion resistance, SBS compound as its modifier for meeting the torched-on applications, it shall be covered with polyethylene membrane(PE),aluminium foil, colorful sand or mineral granule on its top surface and polyethylene membrane(PE)coated on its under face. This series of membrane is designed for the waterproofing of underground construction such as tunnel, subway, basement,roofs and pools etc.      

SBS Membrane installation procedure

1.Base processing:the base surface must be clean,solid,level,dry;no grit,rift and loosing dust. For a large recess,fill it with cement mortar and then level it. Remove the protrusion and clean dust.If working on base slab or lateral face,water lowering should be done.

2. Painting primer:before laying the membrane,clean the dust on the surface of concrete base with dust catcher or dust-blower;then paint entirely with treatment agent of DY primer for waterproofing(for purpose of dust consolidation and high adhesive effect).

3.Heat to melt: place membrane correctly, fire torch, heat the membrane with base entirely, when the surface of the membrane is black and bright with a fusion layer, apply the membrane and press it into a solid and flat state.Before the membrane is cool, seal the edge of joint by float

4.Requirements for lapping: There should be less than 3 layers of lapping, with the joint seams appearing as"T" type,avoid 4 layers of lapping.The width of longitudinal lapping is between 50 and 80mm,and of end-lap joint 100mm
