Option 1: Elastomer-modified asphalt waterproofing membrane with surface layer (colored sand, schist) + elastomer-modified asphalt waterproofing membrane
SBS elastomer modified asphalt waterproofing membrane is a traditional waterproofing material with mature construction technology and low cost. The elastomer modified asphalt waterproofing membrane with surface layer (colored sand, schist) has multiple choices of surface gravel and rock flake colors, which is more beautiful on exposed waterproof roofs.
Option 2: Single-layer exposed thermoplastic polyolefin (TPO) waterproof membrane
Single-layer exposed thermoplastic polyolefin waterproofing membrane can meet the first-level waterproofing requirements of the roof with a single layer. The hot air welding overlap makes the entire membrane waterproof layer truly integrated. The empty paving construction has lower costs, higher efficiency and outstanding cost performance.
