Ultimate Terrace Waterproofing in Mohali
Your roof is your first line of defense. Stop wasting money on cheap tar that melts in the summer and cracks in the monsoon. We engineer permanent, UV-stable polyurethane membrane systems.

Why Mohali Terraces Crack & Leak
Your terrace takes the absolute worst of the Mohali climate. In June, the concrete slab bakes at surface temperatures exceeding 60°C. Two months later, it is subjected to continuous, heavy monsoon downpours.
This rapid thermal expansion and contraction physically tears rigid concrete apart. Micro-fissures open up. The joint where the floor meets the parapet wall separates. The moment water pools on your roof, it uses these cracks to infiltrate your home.
The Trickle-Down Destruction
A leaking terrace isn’t just a top-floor problem. Gravity pulls moisture through the slab, causing compounding damage:
Trapped vapor pressure blows expensive POP ceilings and drywall off the top floor.
Water traveling through ceiling conduits directly shorts out expensive wiring matrices.
4 Critical Signs Your Terrace is Failing
Top Floor Mold
Black or green spots blooming in the corners of your top-floor ceilings indicating heavy slab saturation.
Parapet Separation
Visible, deep hairline cracks forming exactly where the terrace floor meets the boundary wall (the corner joint).
Paint Bubbling
Interior roof paint peeling off in large sheets due to vapor pressure pushing down from the wet slab above.
Ponding Marks
Dark, stained circles on the terrace surface showing where water sits for days after the rain stops.
Why We Trust Fosroc PU Systems
The Old Way Fails
Traditional bitumen (tar) melts under Mohali’s sun, turns brittle in winter, and cracks. Standard cement slurries are rigid; when the slab shifts, the cement cracks instantly, reopening the leak path.
Fosroc Nitoproof Series
We deploy high-end, pitch-free liquid polyurethane. Once applied, it chemically cures into a continuous, seamless, rubber-like membrane across your entire terrace. It has zero joints for water to penetrate.
Aliphatic UV Armor
For exposed roofs without tiles, we apply an aliphatic PU topcoat. Unlike standard chemicals that turn yellow and degrade under UV light, this armor reflects heat and protects the waterproofing layer below for a decade.
Our 5-Step Execution Protocol
Grinding
Using diamond-cup grinders to remove old tar, dirt, and weak concrete laitance down to the solid base.
Angle Coving
Creating a 45-degree mortar fillet (coving) at the exact 90-degree joint where the floor meets the parapet wall.
Priming
Applying an epoxy or PU primer that penetrates deep into concrete pores, acting as the structural anchor.
PU Membrane
Rolling out multiple heavy coats of Fosroc PU liquid membrane, waiting for precise curing between each layer.
Validation
Blocking the drain pipes and flooding the entire terrace with water for 48 hours to confirm zero leakage.

Complete Building Protection
Execution is Everything.
About Us: Rishi Gautam Enterprises delivers goal-focused results. Buying the best Fosroc chemical in the world is useless if the contractor skips the grinding and priming phases to save time. We execute strictly by the book.
Preserve Your PU Membrane
Do not drag heavy metal furniture or sharp tools across an exposed, un-tiled PU membrane roof.
Keep drainage holes entirely free of leaves. While PU handles ponding, active drainage is always the goal.
If you install a solar panel later, have a professional reseal the bolt anchors immediately to maintain the barrier.
Terrace Engineering FAQ
Straight answers to your technical questions.
Should we remove the old brickbat coba before waterproofing?
If the existing brickbat coba is highly cracked and retaining trapped moisture, yes, it must be demolished down to the mother slab. Applying a PU membrane over saturated, failing brickbat will result in trapped vapor blistering the new coating.
Can I install tiles over the Fosroc PU membrane?
Yes. We sand-broadcast the final wet coat of the PU membrane. This creates a rough, mechanical key that allows tile adhesive or cement mortar to bond perfectly to the waterproofing layer.
Can you waterproof over my existing tiles to save money?
Yes, assuming the tiles are sound. We deep-clean the tiles and apply a specialized aliphatic, clear, trafficable polyurethane coating. It seals the porous grout lines and microscopic tile cracks without requiring expensive demolition.
How much does terrace waterproofing cost?
It depends entirely on the square footage, current slab condition, and whether we are doing an exposed application (requires UV aliphatic topcoats) or a concealed application (under tiles). We conduct a free site visit to provide a firm, accurate quote.
