Stop leaks at the source
Dampness on a ceiling is rarely directly under the leak. Water travels through slabs, joints and pipe sleeves before it shows. We inspect first, trace the source, and then choose the treatment, because a coating applied on the wrong surface will not stop a leak.
Waterproofing needs good materials and careful surface preparation, and on larger structures it should be supervised throughout. Dry months are the best time for terrace and exterior work, so plan before October.

FAQs
Waterproofing: common questions
Can't find your answer? Ask us directly. We're happy to explain before you decide.
What is the best time for waterproofing in Chennai?
The dry months before the north-east monsoon, roughly February to September. Terrace and exterior work needs dry surfaces and a few dry days to cure.
Which waterproofing material is used?
It depends on the surface. Polymer-modified cement, acrylic and PU coatings, bituminous membranes and injection grouting are all used for different areas. We name the system in the quote.
Can bathroom leaks be fixed without removing all the tiles?
Sometimes. If the leak is at joints or pipe outlets, grouting and local repair can work. If the waterproofing under the tiles has failed, the floor needs to be redone.
Why does my ceiling leak only in heavy rain?
Usually water is collecting on the terrace because of blocked outlets or poor slope, then entering through cracks. Fixing drainage and treating the slab stops it.
Do you waterproof drinking water tanks?
Yes, using coatings suitable for potable water.
How do you treat wall cracks?
Fine cracks are filled and sealed. Active cracks that let water in are treated by injection grouting, which fills the crack from inside.
