Waterproofing contractors in Chennai.
Terrace and roof leaks, bathroom seepage, damp basements and leaking tanks, diagnosed and sealed by BCR's own crew. Our head office is in Chennai.
Why buildings leak in Chennai
Local weather, local problems.
Chennai combines coastal humidity, salt-laden air and long, hot summers with a short, violent wet season. Terraces bake at over 60°C for months, crack, and then face days of standing water when the north-east monsoon breaks. Low-lying areas see high groundwater, which pushes moisture into basements, sumps and lift pits.
- Annual rainfall
- about 1,400 mm a year
- Monsoon pattern
- Most rain arrives with the north-east monsoon from October to December, often as intense cyclonic downpours.
The problems we fix most in Chennai.
- Thermal cracks on terraces that leak in the first heavy rain
- Seepage in sunken bathroom slabs of older apartments
- Groundwater ingress into sumps, basements and lift pits
- Salt and humidity damage to exposed concrete near the coast
