Why do leakages occur in concrete structures?
Leakages occur because of variety of reasons; some of which are mentioned below – a. Accumulation of water, which start penetrating the surface. b. Poor quality and improper proportioning of concrete constituents that make concrete permeable c. Poor compaction of concrete, which leave a lot of air voids . d. Construction joints at two different works like concrete and brick works, and discontinuity in concrete casting (joint at old concrete and new concrete) leading minute cracks, which facilitate water movement. e. Other structural cracks because of loading conditions and failure of the structure to withstand that stress f. Movement of water from bottom to top because of capillary action.
