This 244 meter long masonry dam in lime mortar was constructed in the year 1931 and had been leaking profusely at a number of points over the period. It had developed large number of voids in the body of dam, as lime mortar had washed out.
50 mm thick guniting on the upstream face of dam in the badly leaking reaches was carried out with cement mortar 1:3. In balance reaches, cement pointing in rich cement mortar was done. To arrest the seepage and to consolidate the body of dam average 18 M deep drilling and grouting by percussive method was carried out through primary and secondary holes.
The drilling was done in two rows 2 M apart with a hole spacing of 3 M centre to centre and staggered. Drilling was performed by descending order method. This treatment has reduced the seepage within permissible limit.
