Society Structural Repair & Building Waterproofing in Mumbai: A Complete Guide

Extending the Lifespan of Mumbai's Aging Societies

With high humidity, salty air, and torrential monsoons, buildings in Mumbai age faster than in other cities. If your Co-operative Housing Society (CHS) is over 20-25 years old, you will likely notice exposed steel (rebar), cracks on the exterior walls, and severe seepage issues. It's time for major structural repairs.

The Structural Repair Process

A proper society repair project is not just about slapping some cement and painting over it. A professional structural repair process involves:

1. Structural Audit: The first step mandated by BMC for buildings over 30 years old. An engineer identifies weak columns, beams, and slabs.
2. Exposing and Treating Steel: The cracked plaster is broken. The rusted steel reinforcement inside is cleaned with wire brushes and treated with a rust-remover and anti-corrosive epoxy coating to stop further rusting.
3. Micro-Concrete & Polymer Plaster: Instead of normal cement, we use specialized polymer-modified mortar and micro-concrete (from brands like Fosroc or Dr. Fixit) to pack the columns and beams. This restores the original strength of the structure.
4. Exterior Crack Sealing: All exterior cracks are opened in a V-groove and filled with elastic crack-sealant.

Building Waterproofing and Exterior Painting

Once the structural repair is complete, protecting the building from future rain is crucial.

• We apply a waterproofing primer (base coat).
• Followed by 2-3 coats of high-performance elastomeric exterior paint (like Asian Paints Apex Ultima Protek), which comes with a 7 to 10-year waterproofing warranty.
