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.

  GROUTING PROCEDURE OF RETAINING WALL:-   Construction & Honeycomb Treatment:-        Chasing open the joints in ‘’V’’ shape/ ‘’U’’ shape groove of required width and depth as per site conditions. Chasing open the junction of RCC and the masonry surfaces, sealing the groove with repair mortar C:M with Conplast WL equivalent @ 150 ml per bag of cement etc.    The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. The required quantity of Conplast WL is measured and stir into the first or second bucket of water. Conplast WL water mixture shall be added to the concrete or mortar and mixed thoroughly. Mixing shall be continued and further water shall be added until the required work ability is obtained. Grouting:- Cementious Grout:- ·     Providing and applying neat cement slurry grouting (Cebex 100) including expandable additive as directed by consultant
