Traditional below-slab tanking requires a complex sequence: pouring lean concrete, priming, torching two layers of bitumen sheets, and adding a “protection concrete” layer to shield the membrane from rebar damage. This consumes valuable schedule time and adds heavy material expenses. Furthermore, if a breach occurs, water travels freely between the concrete and sheet, making the leak source impossible to track.
The Solution: Mechanical Adhesion via Pre-Applied Proof Technology Daumer re-engineers this cumbersome process by deploying smart pre-applied bituminous engineering:
- Single-Layer Blindside Tanking Without Protection Slabs: Applied directly before steel placement, the DAUPRO WATERSTOP TITAN PROOF (PROOF 350 / 450 / 450 PLUS) series features a specialized silica-sand coated SBS matrix. It utilizes the hydration heat of fresh concrete to permanently fuse with the structural slab. It requires no primers, extra felts, or protection concrete, completely preventing lateral water migration. For extreme engineering demands, PROOF 450 PLUS delivers superior mechanical puncture resistance.
- Liquid Membranes and Torch-On Liners: For retaining walls preferring liquid execution, the rubber-modified DAUPRO WATERSTOP PM BITUM 2K (or single-component 1K) builds a seamless high-build groundwater shield. For standard torch applications, depending on the climate profile, our -10°C APP Membranlar or the severe-cold engineered -20°C TITAN SBS Series Membranes ensure robust structural defense.
