Monsoons expose every weakness. Leaking terraces, damp basements, seeping concrete — and most "solutions" fail within 2-3 years.
I've walked into basements in Mumbai where the water was ankle-deep in August. I've seen terraces in Delhi where the brickbat coba had completely separated from the slab, holding puddles of stagnant water underneath. The building owner had spent ₹1.2 lakhs on waterproofing just three years earlier. Completely wasted.
The truth is, traditional waterproofing methods — cementitious coatings, bitumen sheets, brickbat coba, acrylic paints — they all have the same fatal flaw: they sit on top of the concrete. They don't bond with it. Water finds the gap, creeps under the layer, and the whole thing peels off like old paint.
Epoxy waterproofing is fundamentally different. It penetrates the concrete, bonds at a molecular level, and becomes part of the structure itself. That's not marketing talk — that's chemistry.
Bondone Silcrete — The Epoxy Waterproofing That Actually Lasts
Two components. 2:1 mix ratio. 40-50 minutes pot life. And a bond strength that makes traditional waterproofing look like a temporary patch job.
Molecular Bond
Silcrete doesn't just coat concrete — it penetrates the capillary pores and locks in. No gap for water to sneak under. No delamination. Period.
UV + Weather Resistant
Unlike basic epoxy coatings that chalk and yellow under sunlight, Silcrete holds up against direct sun, monsoon pounding, and temperature swings from 5°C to 50°C.
Chemical Proof
Originally designed for pharma plants, battery rooms, and chemical storage facilities. If it can handle acid spills, your terrace rainwater is nothing.
Single Application
One properly applied coat at 300-400 microns gives you waterproofing that lasts 10-15 years. No reapplication every other summer. No annual maintenance headaches.
Important: Silcrete is a waterproofing epoxy — not a self-levelling flooring epoxy. For industrial flooring needs like warehouses or showrooms, use Bondone Flowtop instead. I cover this in detail on the epoxy flooring India page.
Where Epoxy Waterproofing Makes the Biggest Difference
Not every surface needs epoxy waterproofing. But for these applications, nothing else comes close.
🏠 Terrace & Roof Waterproofing
Flat concrete terraces are the #1 source of water damage in Indian buildings. Silcrete creates a seamless, joint-free membrane that handles ponding water — something bitumen sheets can't do once they crack at the overlaps.
🏢 Basement Waterproofing
Below-grade concrete faces hydrostatic pressure from groundwater. Silcrete applied on the interior face stops water ingress even when the water table rises during monsoons — no excavation needed.
🚰 Water Tank Lining
Overhead and underground water tanks develop micro-cracks over time. Silcrete seals them permanently. Potable-water safe once fully cured (typically 7 days).
🏭 Chemical Storage Areas
Battery rooms, pharma storage, chemical bunds — anywhere spills can eat through concrete. Silcrete's chemical resistance protects the slab and prevents structural degradation.
I Lost ₹15,000 on a Waterproofing Job — And Learned This the Hard Way
Early on, I made a mistake that still stings when I think about it. And I'm telling you about it so you don't repeat it.
Back in 2018, a client in Noida called me about a leaking terrace on their 3-storey house. They'd already tried two rounds of cementitious waterproofing. Both failed within one monsoon. I was eager to help — maybe too eager. I recommended a general-purpose epoxy coating I had in stock. It was meant for indoor floors, but I figured: epoxy is epoxy, right? It bonds. It seals. What could go wrong?
Everything. The terrace had ponding water after heavy rain — water sitting for 6-8 hours at a time. The epoxy I'd used wasn't formulated for prolonged water immersion. Within four months, it started blistering. By the next monsoon, it was peeling in sheets. I had to strip it all off and redo the entire 1,200 sq ft terrace — this time with Silcrete. I absorbed the material cost: ₹15,000 out of my own pocket. The labour was another ₹22,000 that neither of us had budgeted for.
Here's what I learned: not all epoxies are waterproofing epoxies. A floor coating resists spills and foot traffic. A waterproofing epoxy resists continuous water exposure, hydrostatic pressure, and UV degradation. They're completely different formulations. Silcrete is built for water. That's its entire job.
That Noida terrace? It's been dry for six years now. The client has since referred me to four other projects. But I'll never forget the sinking feeling of seeing those blisters appear — knowing I'd got it wrong because I hadn't respected the difference between flooring and waterproofing.

Epoxy Waterproofing — Questions Contractors Actually Ask
What is epoxy waterproofing and how does it work?
Epoxy waterproofing uses a two-component epoxy resin system that, when mixed and applied to concrete, penetrates the surface pores and cures into an impermeable, monolithic barrier. Unlike surface coatings that sit on top, epoxy bonds into the concrete itself — eliminating the gap where water normally seeps through. Bondone Silcrete is specifically formulated for this purpose with a 2:1 mix ratio and 40-50 minute pot life at 25°C.
How is epoxy waterproofing different from traditional waterproofing like brickbat coba?
Traditional methods — brickbat coba, bitumen sheets, cementitious coatings — all rely on a physical layer sitting on top of the concrete. Over time, thermal expansion, structural movement, and water pressure create gaps and cracks at the interface. Epoxy waterproofing bonds chemically with the concrete substrate, becoming structurally integrated. No interface gap means no water migration. The trade-off: epoxy requires proper surface preparation and cannot be applied to damp concrete.
Which Bondone product should I use for terrace waterproofing?
Bondone Silcrete is the correct product for terrace waterproofing. It's a 2-component epoxy system designed for concrete protection against water ingress, chemical exposure, and UV degradation. Do not use Bondone Flowtop for terrace waterproofing — Flowtop is a self-levelling industrial flooring epoxy meant for interior warehouse and showroom floors. I've made this mistake myself (cost me ₹15,000), so trust me on this one.
Can epoxy waterproofing be applied on an existing terrace that already has leaks?
Yes — but only after proper surface preparation. The existing surface coating (paint, old waterproofing, laitance) must be removed entirely via grinding or shot-blasting to expose bare, sound concrete. Any active leaks must be stopped and the concrete allowed to dry to below 5% moisture content. Silcrete needs a clean, dry, profiled surface to bond properly. Applying it over old failed waterproofing is throwing money away.
How long does epoxy waterproofing last?
When applied correctly on a properly prepared surface, Bondone Silcrete waterproofing lasts 10-15 years under normal Indian weather conditions. I have installations in Ghaziabad and Noida that are 6+ years old with zero issues. Factors that reduce lifespan: poor surface prep, application on damp concrete, UV exposure without topcoat in extreme sunlight regions, and mechanical damage from heavy objects on the terrace.
What is the cost of epoxy waterproofing per square foot in India?
Material cost for Bondone Silcrete works out to approximately ₹40-48 per sq ft at 400-micron thickness (one 7.5kg kit covers ~75-90 sq ft at ₹3,610). Total project cost including surface preparation, primer, application labour, and Silcrete typically ranges from ₹85-150 per sq ft depending on surface condition, accessibility, and location. Far cheaper than replacing a water-damaged slab.
Is epoxy waterproofing suitable for basement walls that seep water during monsoons?
Yes, but with an important caveat: Silcrete can be applied to interior basement walls to create a negative-side waterproof barrier — but only when the wall is dry at the time of application. If the basement is actively seeping, you must first stop the ingress (injection grouting or exterior excavation), allow walls to dry, then apply Silcrete. Applying epoxy to a wet, actively seeping wall will result in complete failure. I've seen contractors try it — it's ugly and expensive to fix.
Do I need a primer before applying epoxy waterproofing?
Yes. Always. Bondone recommends a compatible epoxy primer applied to the prepared concrete surface before the Silcrete waterproofing coat. The primer seals the concrete pores, improves adhesion, and prevents outgassing bubbles in the waterproofing layer. Skipping the primer saves ₹800-1,200 but risks delamination — not a trade-off worth making.
What's the difference between Silcrete and regular epoxy floor paint for waterproofing?
Regular epoxy floor paint is a thin-film coating (typically 80-150 microns) designed for aesthetics and light traffic on dry interior floors. Silcrete is a high-build waterproofing system (300-400+ microns) formulated for continuous water exposure, UV resistance, and chemical protection. Floor paint fails on terraces because it can't handle ponding water or thermal cycling. Silcrete is built for exactly those conditions. Different chemistry, different application, different result.
