Waterproof coating service in Lucknow

Lucknow has a lot of older buildings with thick walls and lime plaster, alongside modern apartments and commercial complexes. Waterproofing them isn't the same job. Many damp problems in older buildings are made worse, not better, by modern cement plasters and waterproof paints that trap moisture inside the wall. Newer buildings mostly need well-detailed bathrooms, sound tanks and dry basements. We treat each type of building according to how it was built.

Older buildings with lime plaster

Walls built with lime mortar and plaster are designed to "breathe". Moisture that gets in can evaporate back out. When these walls are patched with cement plaster or painted with impermeable coatings, moisture gets trapped. The result is salt bloom, crumbling plaster and damp patches that spread.

For these buildings we:

1. find where water is getting in, whether from rain, rising damp, leaking drains or roofs
2. fix the source, such as drainage, roof leaks or pipes
3. remove damaged cement patches where they are trapping moisture
4. repair with compatible, breathable materials
5. use breathable water-repellent treatments on exposed faces rather than sealed coatings

This is slower than painting over the problem, but it's the only approach that lasts in these walls.

Government and institutional buildings

Government offices, colleges and hospitals often need waterproofing work defined clearly for approval or tender. After a survey, we provide a written scope that separates bathrooms, tanks, walls and basements, with methods and approximate quantities.

Hospital tanks and wet areas

Hospitals depend on reliable water storage. Leaking overhead and underground tanks are drained, repaired at joints and cracks, and coated with potable-water certified products. Hospital bathrooms and sluice rooms that leak into floors below get a membrane under new tiles, tested before retiling.

Apartment bathrooms

In Lucknow's apartment blocks, leaking bathrooms cause damage in flats below. A lasting fix means:

• removing tiles and screed in the affected area
• sealing floor traps and pipe penetrations
• applying a flexible membrane on the floor and up the walls
• a ponding test to check for leaks
• screeding and retiling

Basements

Basements in commercial buildings and hospitals take in water through cracks and joints in the monsoon. Injection seals active leaks, and crystalline or cementitious waterproofing treats walls and floors from inside.

FAQs

Can we use waterproof paint on an old lime-plastered wall?

Usually not. Sealing a lime wall traps moisture and makes damp worse. Breathable treatments are more suitable.

Can you provide a scope for a government tender?

Yes. After the survey we provide a written scope with areas, methods and approximate quantities.

How long does a bathroom waterproofing job take?

Usually several days, including the ponding test and retiling.
