Types of waterproofing membranes
1. SBS modified bitumen waterproofing membrane: This membrane has good high temperature resistance and can be used in the temperature range of -25 to +100 ℃, with high elasticity and fatigue resistance, and up to 1500 % elongation and strong puncture resistance and tear resistance. It is suitable for waterproof projects in cold areas, as well as industrial and civil buildings with large deformation and vibration.
2. Self-adhesive waterproof membrane: It is a kind of self-adhesive rubber asphalt prepared with synthetic rubber such as SBS, tackifier road petroleum asphalt as the base material, and strong high-density polyethylene film or aluminum foil as the upper surface material. The peelable silicon-coated release film or silicon-coated release paper is a waterproof material made of an anti-stick release material on the lower surface. It does not need adhesives, nor does it need to be heated and baked to melt, and it can be firmly bonded to the base layer only by tearing off the isolation layer.
3. Asphalt waterproofing membrane: Asphalt waterproofing membrane is a rollable sheet-like waterproofing material made by infiltrating the base tire (such as base paper, fiber fabric) with asphalt, and then spreading powdery or sheet-like insulating material on the surface. .
3. Modified bitumen waterproofing membrane: Compared with the traditional oxidized bitumen, the temperature range of modified bitumen is greatly expanded. With 15--20 years of reliable waterproof effect. Can be divided into: 1. Elastomer modified asphalt waterproofing membrane (SBS membrane). Plastomer modified bitumen waterproofing membrane (APP membrane).
