Characteristic:

  • a) SBS modified bitumen waterproof membrane is specially used as waterproof material in cold area
  • b) APP is specially suitable for areas of high temperature and of strong sun-shine
  •     SBS/APP Modified Bitumen Waterproof Membrane
  • c)Good performance in Good impermeability ,anti-puncture, anti-broker, anti-resistance, anti-erosion,           anti-mildew, anti-weathering
  • d)Possess good tensile strength, elongation rate and size stability which could be well suited the                  substrate distortion and crack

Construction Method:

The special formulation of fire enables the membrane to be applied directly with primer. This application is named as "Torched on application".  

  • 1.Base processing: the base surface musts 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
  • 5.Use a roller to push hard the membrane surface to ensure it stick firml

 Packaging and storage

1)Avoid insolating, raining; the temperature shall be 4-45°C;

2)Keep them stand up and vertical; 

3)Do not stack up over two tiers, avoid tilting and lateral drift.
