Aquatorch SBS -Elastomer modified bitumen waterproof membrane (Salt-alkali-resistant ver.)-Aquatorch SBS(Salt-alkali-resistant ver.)


SBS elastomer modified asphalt waterproofing membrane is modified by adding styrene-butadiene-styrene (SBS) and elastomer resin to high-quality asphalt, with compound salt and alkali resistance additives to improve the material's resistance to chloride ion penetration and Salt-alkali corrosion resistance, the high polymer modified asphalt material is formulated through a special process, and the middle reinforced carcass and the outer cover are composed of various surface materials


  • Suitable for roof and underground waterproof and anti-seepage works of industrial and civil buildings;
  • Applicable to swimming pools, fire pools and other structures waterproofing works;
  • Applicable to subways, tunnels, concrete paved roads, bridge decks, sewage treatment plants, garbage dumps;
  • Waterproof and anti-seepage projects for municipal projects such as buried sites;
  • Suitable for waterproofing projects of water conservancy facilities such as canals and pools;
  • It is suitable for underground buildings in coastal areas and high salinity areas, as well as waterproofing projects, such as tunnels and oil depots.


  • Excellent low temperature resistance, especially suitable for use in cold areas;
  • High tensile strength, high elongation, strong adaptability to base shrinkage deformation and cracking;
  • Excellent crack resistance, tear resistance, corrosion resistance and weather resistance;
  • The hot-melt construction can be used all year round, and the seams are reliable and durable;
  • Excellent resistance to chloride ion penetration, meeting the requirements of JTJ 275-2000 "Technical Code for Anti-corrosion of Concrete Structures in Harbor Engineering";
  • Good salt and alkali corrosion resistance, long time in high saline and alkali environment, waterproof performance, excellent durability, no decay;
