The condition of the lime terracing - whether it was hard and compact and only one or two weak spots were there or the entire terracing had become spongy or had become loose. The exact weak point in the lime terracing, and and has come out oozing through the R.C.C. Rain water has entered through the leaky spot in the lime terracing and has travelled through the contact surface of the two layers - e.g.
R C BUILDER PATCH
It may so happen that the leakage in the water proofing course is not at the same spot where the damp patch is observed in the ceiling. The choice of method would depend upon the situation and time available for taking remedial measure.īefore deciding upon the method of remedial measures, a thorough investigation need be made to ascertain the exact location of leakage in the lime terracing layer. There are methods for temporary and permanent remedy. There are various methods of handling the leakage problem suitably according to the degree of damage. construction are to be taken to ensure that the shuttering mould was water-tight, the props did not yield or were not dislodged, packing and compacting of concrete by vibration, maintaining the desired water-cement ratio and consistency of concrete etc. This also shall be taken care of and constant watch shall be kept during pouring of concrete and afterwards so that the shuttering and the staging are not disturbed.Īpart from these, other normal precautions required for R.C. The top of the slab generally comes down a bit for the same reason and due to inadequate strength of the staging and shuttering. This should be taken care of by suitably providing chairs made of steel bars so that the steel remains at the correct position. This decreases the lever arm of the steel resulting in lesser moment of resistance. The tensile steel provided at the support for the negative moment gets pressed due to walking of the labourers over it. While designing, precaution shall be taken to provide adequate thickness of the slab and reinforcement at the support and also adequate development length of the reinforcement beyond the wall, so that they can develop adequate stress.ĭuring construction, before shuttering and laying of reinforcement, the top of the wall shall be plastered and smoothened.
