About Zala Buildco
Welcome to Zala Buildco, your trusted partner for high-quality building renovation and advanced waterproofing services in Mumbai. We specialize in structural restrengthening, terrace waterproofing, APP/EPDM membrane treatment, PU injection grouting, and interior/exterior painting. Whether you require commercial civil maintenance or residential renovation, Zala Buildco delivers long-lasting structural solutions tailored to your needs across Mumbai.
The company is led by a professional civil engineer. That one fact changes how a job runs: every site is properly diagnosed before a system is chosen, the specification is matched to the actual condition of the slab, and the work is supervised technically from first visit to handover.
We use advanced materials and engineering-approved methods, so the repair holds through the monsoon and the years after it — instead of returning next season.
View Our WorkOur Leadership
Zala Buildco has been a family firm since day one — and the approach has not changed, only the tools have.
Founder · 1982
Founded Zala Buildco in 1982. At a time when water leakage was a persistent problem in Mumbai's climate, he spent years studying the chemistry of construction materials rather than settling for surface fixes.
To eliminate leakage, you must eliminate its root cause.
Co-founder · Leading the firm today
A qualified B.Tech in Civil Engineering, carrying his father's method forward with modern engineering science. Every site is diagnosed before a system is specified, and the work is supervised technically from first visit to handover.
Inspect, diagnose, then treat — never quote without understanding.

Every step happens before the next one — which is why the system we apply matches the problem you actually have.
You call or send an enquiry. We visit, inspect the affected areas and understand the history of the leakage.
Moisture detection, visual analysis, crack tracing and slope inspection — to find the source, not the stain.
The engineer specifies the right system — membrane, coating or repair — for your slab, exposure and budget.
Our trained team applies it under supervision with branded materials. Warranty terms are issued on completion.
