Cantilever Balcony Seepage & Edge Drip Treatment in Jubilee Hills Residence
!
The Water Ingress Problem
An exposed cantilever balcony subjected to driving monsoon rain had poor gradient and defective skirting joints. Water leaked downward through the slab edge, corroding reinforcement rebar and causing ceiling plaster collapse on the portico below.

Engineering Treatment & Execution
1. Chipping out corroded concrete and passivating exposed rebar with zinc-rich anti-corrosion primer.\n2. Micro-concrete structural reinstatement with polymer bonding agent.\n3. Creation of 50mm coved fillet angle at all floor-to-wall junctions.\n4. Dual-coat hybrid aliphatic polyurethane UV-stable waterproof membrane installation.\n5. Creation of drip mold groove (chhajja drip) on balcony underside to eliminate capillary travel.
Balcony Waterproofing Case Study: Stopping Structural Corrosion
Balconies in Hyderabad are heavily exposed to direct sunlight and wind-driven rain. When waterproofing fails at the corner joints, water migrates horizontally beneath the tile bedding, attacking the steel rebars inside the cantilever slab.
Structural Restoration & Weatherproof Coating
Our engineers carried out structural rebar passivation followed by the installation of a UV-resistant elastomeric polyurethane membrane capable of 350% elongation. This ensures structural movement and thermal contraction never crack the waterproofing barrier.
