Why Your Bangalore Home Needs Waterproofing
Bangalore receives nearly 970mm of rainfall across 60+ rainy days each year. Combined with the city's rapid construction boom since the 2000s, thousands of apartments and villas suffer from persistent leaks, seepage, and dampness — especially buildings that are 8-15 years old.
Untreated water damage leads to structural weakening, rebar corrosion, electrical hazards, fungal growth (black mold), and massive drops in property value. The longer you wait, the more expensive the fix becomes.
Our Waterproofing Services
🏗️ Terrace & Roof Waterproofing
We apply advanced polymer-modified cementitious coatings, APP/SBS membranes, and polyurethane liquid membranes to permanently seal your terrace. Every solution is tailored to your roof type — flat RCC slab, sloped roof, or terrace garden.
| Method | Cost (per sq ft) | Warranty | Best For |
|---|---|---|---|
| Bitumen coating | ₹29–₹35 | 5 years | Budget terrace sealing |
| Polymer cementitious | ₹45–₹55 | 7 years | Most apartments |
| APP membrane | ₹55–₹70 | 10 years | Severe leaks, old buildings |
| PU liquid membrane | ₹68–₹83 | 10 years | Terrace gardens, heavy traffic |
🚿 Bathroom Waterproofing (Without Breaking Tiles)
Our non-destructive injection grouting technique seals bathroom leaks without demolishing tiles. We inject epoxy or polyurethane grout through micro-holes into the substrate, filling cracks and voids to create a permanent waterproof barrier.
Cost: ₹8,000–₹25,000 per bathroom depending on severity. 5-year warranty included.
🏢 Basement & Sump Waterproofing
We use crystalline waterproofing (Xypex/Fosroc technology) that penetrates deep into concrete pores and self-heals micro-cracks. Ideal for apartment basement parking, underground sumps, and lift pits.
Cost: ₹50–₹75 per sq ft. 7-10 year warranty.
🧱 External Wall Seepage Treatment
Damp walls, peeling paint, and fungal patches on exterior walls are treated with elastomeric acrylic coatings and silicone-based water repellents that allow the wall to breathe while blocking water ingress.
Cost: ₹40–₹60 per sq ft. 5-year warranty.
⚡ Expansion Joint & Structural Crack Repair
Movement joints between buildings, terraces, and podium slabs are sealed with flexible PU sealants and backing rods. Structural cracks are repaired with epoxy injection before waterproofing.
