System and method for mounting a waterproofing system to shoring for an excavation wall

A method for mounting a waterproofing system comprising a waterproof membrane to shoring within an excavation for a wall of a structure, comprising:

• securing a first hydrophilic washer between the waterproof membrane and an induction disc, the induction disc having a conductive element, a first disc surface coated with an adhesive, and a second disc surface opposite the first disc surface, the first hydrophilic washer secured between the waterproof membrane and the second disc surface;
• affixing a target patch to the induction disc, the target patch having a first patch surface and a second patch surface opposite the first surface, by induction welding the first patch surface to the first disc surface, the target patch having an outer portion which extends beyond the periphery of the induction disc;
• securing a second hydrophilic washer between the second patch surface and a rigid washer;
• inserting a mounting fastener through the rigid washer, the second hydrophilic washer, the target patch, the induction disc, the first hydrophilic washer and the waterproof membrane;
• fastening the mounting fastener into the shoring;
• and
• affixing the outer portion of the target patch to the waterproof membrane.
