A guy I know in Naranpura got his terrace waterproofed in March last year. Paid a decent amount for it, felt good about it, told everyone he was “monsoon ready.” By August, there was a fresh stain on his kitchen ceiling, same spot as two years before. He called the same contractor, who basically told him this happens sometimes and offered to redo it for another 60% of the original cost.
If this sounds familiar, you’re definitely not alone. It’s one of the most common complaints homeowners have after hiring a waterproofing company in Ahmedabad, they pay for the work, it looks fine through the dry months, and then the first heavy spell of rain in July finds a way through anyway. So what’s actually going on here?
It’s rarely the “waterproofing” itself that fails
Most people assume the coating or membrane simply wore out. Sometimes that’s true, but more often the real issue happened before the waterproofing was even applied. If the surface wasn’t prepared properly, if cracks weren’t filled, if the slope wasn’t corrected for water to drain, then no amount of coating on top is going to hold for long. It’s a bit like painting over a wall with damp still inside it. Looks fine for a while, then it doesn’t.
Cheap materials that can’t handle Ahmedabad’s heat
Summers here regularly cross 43-44°C, and that kind of heat causes concrete to expand and contract more aggressively than in cooler cities. A lot of contractors use whatever cement-based waterproofing compound is cheapest, and those coatings crack under this kind of thermal stress within a year or two. It’s not that waterproofing “doesn’t work” in Ahmedabad, it’s that the wrong material for our specific climate fails faster here than it would elsewhere.
Joints, pipe openings, and parapet walls get skipped
This is the part that gets ignored most often. The flat area of a terrace is easy to coat evenly. The tricky spots, where a pipe passes through the slab, where the parapet wall meets the floor, around drain outlets, need proper sealing and flashing work. A rushed job usually covers the flat surface nicely and just brushes over these junction points, which is exactly where water finds its way back in a year later.
No slope correction, so water just sits there
If your terrace doesn’t have a proper slope toward the drain outlets, water pools instead of flowing off. Standing water puts constant pressure on any waterproofing layer, and eventually it seeps through even a decent coating. A lot of contractors skip this step entirely because correcting the slope takes more time and material than just applying a coat and calling it done.
The warranty was never really a warranty
This one’s common and honestly a bit sneaky. Plenty of homeowners were told “5-year warranty” without anyone explaining what that actually covers. When the leak comes back, the contractor conveniently says it’s a “new” problem, unrelated to the original work, and outside the warranty. Unless the terms were written down clearly at the start, there’s not much you can do about it after the fact.
What actually needs to happen instead
Waterproofing done right for Ahmedabad’s climate isn’t a one-step process. It usually needs proper surface cleaning and crack filling first, correction of slope where needed, careful treatment of all joints and pipe openings, and then application of a coating or membrane suited to handle both the summer heat and monsoon load, not just one or the other.
This is where a company like Prakshal Group approaches things differently. Working across Ahmedabad for over two decades, including large commercial and institutional structures, they focus on getting the surface preparation and detailing right first, rather than rushing to the visible coating step. Their site inspections are aimed at identifying exactly why a terrace is failing before recommending a fix, which is honestly the step most homeowners skip when they just want the leak gone before the next rain.
If your terrace is leaking again this year
Before paying for a repeat job, ask the contractor to actually explain why the previous waterproofing failed. If they can’t give you a clear answer beyond “it happens,” that’s worth noting. A proper diagnosis before any repair work is really the only way to stop this cycle of redoing the same job every couple of years.
FAQs
Why does my terrace leak even after waterproofing? Usually because the underlying surface wasn’t prepared properly, joints and pipe openings weren’t sealed, or the material used couldn’t handle Ahmedabad’s heat and monsoon cycle together. The visible coating can look fine while the actual problem sits underneath it.
How long should terrace waterproofing last? Done correctly, it should hold for 8 to 10 years, sometimes longer, depending on the terrace’s usage and exposure. If it’s failing within a year or two, something in the original process was likely rushed or skipped.
Can I fix a leaking terrace without redoing the entire waterproofing? Sometimes, if the failure is localized to a joint, crack, or a specific patch, a targeted repair can work. But this needs a proper inspection first to confirm the rest of the surface is actually intact.
Is it worth paying more for a better waterproofing company? Generally yes. The cost difference between a rushed job and a properly done one is usually much smaller than the cost of redoing the whole terrace every couple of years, not to mention the interior damage a recurring leak causes.
