Exterior Wall Waterproofing
Damp patches that appear only after heavy rain usually trace back to the exterior wall surface, not the interior.
Typical Symptoms
How this usually shows up
- Internal damp patches appearing after heavy rain
- Peeling exterior paint
- Cracks visible on the external wall face
- Damp patches concentrated near window frames
Common Causes
What's usually behind it
- Hairline cracks allowing wind-driven rain ingress
- Failed sealant around window and door frames
- Porous or degraded plaster
- Missing protective coating on exposed walls
Treatments We Apply
The right treatment depends on substrate, severity, and exposure — determined during assessment.
Elastomeric Coatings
Epoxy / Crack Injection
Construction Joint Sealing
Our Process
We assess the wall face for cracks, porosity and frame sealant condition, then apply crack repair followed by a breathable protective coating suited to the exposure direction.
