DAUPRO WATERSTOP PROOF is an under-slab tanking membrane applied prior to concrete pouring that forms a permanent bond with the surface via the hydration heat of the concrete. The SBS-modified polyester structure, 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 35: 3.5 mm thickness — For standard projects. • PROOF 45: 4.5 mm thickness — For projects requiring high performance.
FIELDS OF APPLICATION • Single-layer waterproofing applications under raft foundations, • Shear and retaining walls, • Elevator pits, • Parking lot floor slabs, • Basement sub-structure applications.
