"Waterproofing of pipe penetration at the Numbers junction of pipe and RCC roof all complete as per direction of the Engineer-in-charge. Following steps are involved: 1. Cutting & Preparation: Cut the junction of pipe-to-slab at least 2 to 4 inches all around the pipe. Cut floor level up to 2 inches depth to expose the mother RCC slab. Remove loose concrete & debris. 2. Surface Preparation: Wire brushing around pipes for proper bonding. Clean debris, dust & rust from GI pipe surfaces. Apply rust remover if required. 3. Epoxy Injection / Epoxy Base Grout Filling: Pour Fosroc epoxy-based grout into the groove up to 10 mm thickness. Ensure epoxy penetrates into cavities & microcracks. Allow to cure as per Fosroc guidelines. 4. Fosroc GP2 Micro-Concrete Grouting: After epoxy cures, fill the remaining depth with Fosroc GP2 micro-concrete. Compact manually to avoid air voids.
