Balcony waterproofing
Balconies take rain, sun and washing water on an exposed edge. When the joints open, water goes into the wall and the ceiling below, and you see stains long before you see a crack.
Signs you need it
- Stains on the ceiling below the balcony
- Damp or peeling paint where the balcony meets the room
- Water pooling against the door sill
- Loose or cracked tiles and open grout
Common causes
- Floor slope that sends water toward the wall
- Open tile joints and failed sealant
- Cracks at the junction with the building wall
- Blocked or missing drain outlet
How we do it
- Inspect slope, drainage and joints
- Repair cracks and re-seal junctions
- Apply the waterproofing coats
- Test with water and hand over
