Balcony Waterproofing
Balconies face constant weather exposure with limited drainage — small gaps in protection show up fast.
Typical Symptoms
How this usually shows up
- Efflorescence (white salt deposits) on the underside
- Dripping visible below the balcony slab
- Slab edge or railing base damage
- Cracking near the balcony-to-wall junction
Common Causes
What's usually behind it
- Cracked or missing drainage slope
- Failed junction sealant between balcony and wall
- Deteriorated waterproofing coating
- Water pooling at railing bases
Treatments We Apply
The right treatment depends on substrate, severity, and exposure — determined during assessment.
Elastomeric Coatings
Construction Joint Sealing
Crystalline Waterproofing
Expansion Joint Treatment
Our Process
We check drainage slope, junction seals, and coating condition, then apply a weatherproof system designed to handle direct sun and rain exposure without cracking over time.
