Balcony & Podium Waterproofing in Hyderabad
Balconies and podium decks are exposed to direct rain from above while also expanding and contracting daily with temperature changes — a rigid waterproofing coating will eventually crack under that constant movement. We use flexible polyurethane and acrylic membrane systems specifically because they can stretch and flex with the slab instead of cracking, which is the most common reason balcony waterproofing fails within a year or two.

Common Causes We See in Hyderabad
- Rigid, non-flexible coatings cracking under daily thermal expansion and contraction
- Poor waterproofing detail at the balcony-to-wall junction, a common leak point
- Ponding water from incorrect slope toward the drain outlet
- Cracked or debonded tiles letting water reach the membrane below
- Podium decks over parking or utility areas facing constant water exposure with heavy foot/vehicle traffic
Our Process
- 1 Surface inspection and cleaning
- 2 Primer application
- 3 Flexible polyurethane or acrylic membrane application
- 4 Protection screed over membrane
- 5 Final check — tiling can proceed after curing
Frequently Asked Questions
Why does balcony waterproofing fail faster than terrace waterproofing?
Balconies typically have more wall junctions, door thresholds, and railing posts penetrating the surface — each one is a potential leak point, and the slab moves more due to being a cantilevered or thinner structural element.
Can this handle podium decks with vehicle traffic?
Yes, for podium decks over parking areas we use a heavier-duty membrane system with a reinforced protection screed designed to handle vehicle loads, not the standard residential balcony system.
Do I need to remove the balcony railing during treatment?
Where railing posts penetrate the slab, we seal around the base rather than removing the railing, unless the post itself is the source of an active leak.
How soon can I use the balcony after treatment?
The membrane needs to cure before the protection screed and tiling can go over it — typically 3–4 days total before the balcony is back in normal use.
