DualProof – Pre-applied, fully bonded membrane
Delta DualProof is a fully and permanently bonded, Pre-Applied, Type A waterproofing membrane. DualProof is a continuous Type A waterproofing system for pre-application seals foundations, below ground surfaces of floors and walls and details of reinforced concrete earth retaining structures. Delta DualProof is applied before steel reinforcement is fixed and concrete poured.
The special non-woven PPFleece of DualProof is co-extruded with a highly flexible, water and gas resistant, transparent PVC layer. Freshly poured concrete forms a strong mechanical bond with the PP-Fleece, preventing water tracking between the membrane and the concrete once cured. DualProof can be installed without heat or open-flame, overlapped and sealed with butyl tape and special adhesive, CEM 805 for detailing. DualProof has excellent crack-bridging capabilities at locations where cracks occur within the concrete.
