A tank that leaks wastes water and quietly damages whatever sits under it. A tank with the wrong lining can affect the water inside it.
Overhead tanks crack from thermal movement and from the constant load cycle of filling and emptying. Underground sumps take pressure from both directions at once — water inside pushing out, ground water outside pushing in. In both cases, once a hairline crack forms it grows, and the leak that started as a damp patch on the wall below becomes a structural problem.
Then there is the lining itself. A coating that is perfectly fine on a terrace is not necessarily safe inside a tank that holds drinking water. If your stored water has developed a taste or a smell, the lining is one of the first things worth checking, along with the tank cover and how often it is cleaned.
Agra water is hard, and hard water is not kind to tank linings over time. Tanks that were coated a decade ago are usually due for inspection.
Loose coating, scale and deposits come off. We need to see the actual concrete to judge what is happening.
Cracks are cut out and filled, construction joints are treated, and spalled concrete is made good. Structure first, coating second.
And for drinking-water tanks, one rated as safe for potable water. This is not a place to substitute a cheaper general-purpose coating.
A tank lining that is filled before it has cured properly will fail, and you will not find out for months.
We fill and check before the tank goes back into normal service.
An overhead tank sitting on a terrace is one of the most commonly missed sources of terrace-level leakage. Water escaping from the tank keeps a patch of the slab permanently wet, which then fails long before the rest of the terrace does.
If we are inspecting a leaking terrace and there is a tank on it, we check the tank too. It costs you nothing extra and it occasionally turns out to be the whole answer.
A terrace-mounted tank and the terrace under it are usually worth treating in one visit.
Underground sumps and basements share the same pressure conditions.
We will come and look, tell you what is actually causing it, and quote only what it needs.
