DAUPRO WATERSTOP PROOF is a special waterproofing system applied prior to concrete pouring that forms a permanent bond with the surface via the heat of hydration of the concrete. The SBS-modified polyester membrane, with its top surface coated with silica sand, is applied in a single layer; it requires no protection concrete, primer, or geotextile felt on top. While saving both labor time and project costs, this structure operates safely even in structures under the most challenging hydrostatic pressure.
SERIES MODELS • PROOF 350: 3.5 mm thickness — For standard projects. • PROOF 450: 4.5 mm thickness — For mid-to-high segment projects. • PROOF 450 PLUS: 4.5 mm thickness — For high-strength and extreme conditions.
FIELDS OF APPLICATION • Single-layer waterproofing applications under raft foundations, • Shear and retaining walls, • Elevator pits, • Parking lot floor slabs, • All structural elements under hydrostatic pressure. • (The PROOF 450 PLUS model should be specifically preferred for projects requiring higher mechanical strength).
