How we work
From first call to a dry ceiling.

Treatment by our own crew
Surface prep, application and curing by trained BCR staff. We never hand your job to subcontractors.
4
Tested before handover
Flood or pond tests on terraces and wet areas, a clean site, and warranty terms explained up front.
Questions, answered.
What do you waterproof?+
Terraces and roofs, walls, bathrooms, lift pits, water tanks, sumps and basements, and industrial roofs and floors. We also do injection grouting for cracks and active leaks, and heat-reflective and cool roof coatings.
Do you need to inspect the source of the leak?+
Yes. Water often shows up a long way from where it gets in. A ceiling patch can come from a terrace crack, a sunshade, a bathroom above or a pipe in the slab. Treating only the stain rarely lasts, so we trace the source before recommending a repair.
Can leaks be repaired during the monsoon?+
Some can. Injection grouting can often be done on wet concrete, so active leaks through cracks and joints can be treated in the rainy season. Most terrace coatings and membranes need a dry surface, so that part of the work is planned for a dry spell. We'll explain what can be done now and what should wait.
Which parts of Chennai do you cover?+
Our office is in Velachery and our crews work across Chennai, including Adyar, Anna Nagar and OMR. Tell us your locality when you call or WhatsApp and we'll confirm.
