11 No PLUGGING WATER LEAKS Locate source of leakage in the concrete. Rout out the leak in a U-shaped configuration to sound concrete, minimum (50 mm) deep and (5 mm) wide. Clean cavity and remove any excess water. Form a plug with AQUAFIN-PLUG-IC or AQUAFIN FIX 0-S and press this into the cavity, filling to approx. depth. Hold this in place for about 0-60 seconds, until it has set. In case of a strong water flow, insert a drain (i.e. /8 - / clear plastic pipe) into the cavity immediately before inserting the PLUG-IC or FIX 0-S. When plug is fully hardened and leakage has stopped, remove any excess material and prime remaining cavity with one slurry coat of AQUAFIN-IC. While slurry is still moist ( green ) fill cavity flush to surface with AQUAFIN MORTAR-IC. Where a drain has been used, carefully remove drain soonest next day, or when mortar has reached at least / of its final strength, and plug the remaining hole as described above. When mortar has set, apply surface waterproofing (AQUAFIN-IC, AQUAFIN-K or AQUAFIN-K/M) over concrete surface. Refer to product data sheets for further information. AQ 0/06
