Application Guidelines & Installation Method
Step 1: For reinforcement mesh, ensure a clean, sound substrate, cut and position the mesh to the approved detail, provide required overlaps, secure it against movement and apply the specified waterproofing or coating layer.
Step 2: For PVC waterstops, position centrally along the joint, secure with suitable clips or fixings, maintain continuous alignment, avoid damage and ensure every joint is correctly welded and watertight.
