Pre-applied Waterproofing Membranes Composite Mechanism and Instructions for professional Execution

As additional sealing for structural integral waterproofed constructions, pre-applied waterproofing membranes can be used. The systems are applied on the water side before pouring the concrete and can develop a tear-resistant bond to the concrete. By the two-parted section, consisting of a ductile sealing layer and a bonding zone, a crack bridging effect and resistance against lateral water migration between the membrane and the construction should be achieved. This article shows the technology and mechanisms and discusses the application potential. Further, practice-oriented investigations will conclude in instructions for execution.
