Roof waterproofing is the single most important protective layer on any building. Water finds its way in through hairline cracks, expansion joints and poor slab curing, and once inside it travels — staining ceilings, corroding reinforcement steel and shortening the structural life of the building. Our roof waterproofing service starts with a moisture survey, followed by surface preparation (cleaning, crack filling and priming), then application of a hydrophobic membrane system matched to your roof type — flat RCC slab, sloped tin sheet, or a green/podium roof. We use liquid-applied membranes, torch-applied bituminous sheets, or polyurethane coatings depending on exposure and budget, finished with a protective top coat rated for UV and foot traffic.
