  •  Cleaning of RCC member should be done by hacking tool, wire brush, wire grinder & air blower etc.

·         All visible cracks & construction joints should be sealed with cement mortar with additive Conplast  WL after making V groove.

           All clean & treated area should test for water tightness by flooding water for minimum 75 mm head for 48 hours. 


   All wet spots, water leak & honeycomb areas should be mark for treatment. It shall be treated with        injection grouting with Cebex 100 as additive to be added in grout cement slurry @ dosage of 225         gm.  of packet per bag of cement or micro concrete.

·       Areas to be grouted should be prepared to ensure substrates are clean, sound, and then pre-wetted. The unrestrained surface area of the grout must be kept to a minimum. Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process. Adopt usual placing or pumping procedures ensuring a continuous operation.
