Abstract:
Method for the waterproofing covering of at least one of joints and cracks in one of hydraulic structures, concrete structures and masonry structures, using a waterproofing first membrane comprising a strip of elastically yieldable synthetic material, which is positioned along a joint or crack on an existing surface of at least one of the hydraulic and masonry structure to be protected, the method comprising the steps of:positioning at least one support element of rigid material on the existing surface of at least one of the hydraulic, the concrete and the masonry structures, to cover at least one of the joint and the crack, and to provide a supporting surface for the membrane; anchoring said support element across at least one of the joint and the crack to allow a sliding movement in respect to said existing surface; positioning at least one protection substrate for the membrane, over the support element; positioning a second membrane between the at least one protection substrate and the waterproofing first membrane to allow a sliding movement of the waterproofing first membrane in respect to the support element and the existing surface; placing the waterproofing first membrane over the protection substrate and the support element; and watertightly fastening peripheral edges of the waterproofing first membrane to the existing surface of at least one of the hydraulic and of the masonry structure, along the sides of at least one of the joint and the crack.
