Bhawani Technologies provides permanent roof leakage repair in Delhi NCR for residential homes, apartment buildings, commercial properties and industrial structures. If your roof leaks every monsoon despite repeated paint-based or patch repairs, the problem is not cosmetic — the underlying waterproofing system has failed and requires a professional, system-based fix.
Our approach begins with a free, detailed inspection using moisture meters and visual diagnosis to identify the exact source of leakage before touching a single tile. We apply the right waterproofing system, not a temporary coat that fails in the next rain. Every job is backed by a written service warranty.
Why DIY and Paint-Based Roof Fixes Always Fail
Most homeowners try waterproof paint, bitumen paint or putty to fix a leaking roof. These work for 3–6 months at best. The reason: surface coatings cannot bridge the dynamic cracks and movement in the concrete slab caused by temperature changes, building settlement and structural loading. A system-based solution — membrane or PU coating — bonds to the substrate, bridges cracks, and creates a continuous waterproof barrier that lasts 7–15 years.
Common Causes of Roof Leakage in Delhi
- Cracks in the roof screed or concrete slab — very common in buildings over 10 years old
- Deteriorated or failed waterproofing joints and membrane laps
- Blocked or poorly designed roof drains causing chronic water ponding
- Parapet wall cracks at the roof-wall junction — a major leakage entry point
- Corroded or poorly sealed pipe and service penetrations through the roof slab
- Age-related failure of original waterproofing — most systems last only 5–8 years without maintenance
Our Roof Leakage Repair Methods
APP/SBS Bituminous Membrane: A 4mm torch-applied membrane applied in two layers. Creates a completely waterproof, highly durable barrier. Best for large roof areas with significant cracking or older failed waterproofing systems. Lifespan: 10–15 years.
PU (Polyurethane) Liquid Waterproofing: A seamless liquid-applied coating with high elongation — bridges cracks up to 3mm width. Excellent for roofs with complex details, multiple pipes or service penetrations. UV-stable and flexible across Delhi's extreme temperature range. Lifespan: 7–10 years.
Injection Grouting: For active leaks through concrete cracks, we inject polyurethane foam or epoxy resin under pressure to permanently seal the crack from within. Fast-setting and highly effective for basement ceilings, water tanks and structural cracks.
Acrylic / Polymer-Modified Coating: A cost-effective solution for minor surface cracks and hairline leakage. Suitable as a maintenance treatment on relatively new roofs showing early signs of leakage.
