Why RCC tanks develop leaks over time
Concrete is naturally porous at a microscopic level, and constant water pressure combined with age, minor structural cracks, and construction joints can gradually let water seep through tank walls, especially in older or underground tanks under more sustained pressure.
Signs your tank needs attention
Damp patches or water marks on the outside of an underground or semi-buried tank, visible cracks on tank walls, or a noticeably faster-than-expected drop in water level can all indicate a leak worth investigating.
Treatment options
Crystalline waterproofing coatings that penetrate and seal concrete pores from the inside are common for water tanks since they do not affect water potability once cured, alongside crack injection for any visible structural cracks.
Getting it checked periodically
Tanks are easy to overlook since they are often out of sight, but periodic checking — especially for tanks over 8-10 years old — can catch small cracks before they become bigger leaks. A free inspection can assess both overhead and underground tanks.
