Balcony waterproofing seals an open external floor against rain and washing water, correcting the fall so water runs to the drain, then tanking the surface under the tiles and testing it before reinstatement.
Balconies and terraces fail because water sits where the fall is wrong, then finds the failed layer under the tiles and tracks into the wall or the room below. Grout and tile are not the waterproofing, the layer beneath them is, and on a balcony that layer takes sun, heat and standing water.
Why balconies leak
The usual causes are a flat or reversed fall that ponds water, a failed or missing membrane under the tiles, a drain that was never sealed into the waterproofing, and cracked grout treated as if it kept water out. Dubai sun and thermal movement age the details fastest, which is where the failures start.
How we seal a balcony
We correct the fall so water runs to the drain, prepare and prime the surface, treat the upstands and the drain with reinforcing detail, and apply a membrane suited to an exposed floor, typically a polyurethane liquid membrane that forms seamlessly around the details. Then we flood test and confirm it holds before the finish goes back.
Fall correction
Rebuilding the slope so water runs to the drain instead of ponding.
Upstand and drain detailing
Sealing where the floor meets the wall and into the drain, the first failure points.
Exposed grade membrane
A membrane matched to sun, heat and standing water on an open floor.
Flood test before finish
Water held and confirmed before the tiles or finish go back.
