Remedial
Waterproofing.
Investigation and rectification of failed membranes, leaking balconies, planter boxes and decks.
Remedial Waterproofing in Sydney & Greater Sydney
Class 1 · Class 2 · Class 3 Buildings — NSW
Remedial work starts with understanding why the original system failed. We trace the path of the water — terminations, penetrations, falls, drainage and junctions — before any scope is priced.
Rectification then addresses the substrate, the detailing and the membrane, not only the symptom that was reported.
Scope of Works
- Failed membrane removal and replacement
- Balcony and terrace rectification
- Planter box relining
- Substrate repair and re-falling
- Drainage and outlet correction
- Defect rectification works

Detail
What Matters Here.
Diagnosis
Water rarely enters where it appears. The cause is identified before a scope is written.
Occupied buildings
Staging, access, noise and programme planned around residents, tenants and trading businesses.
Reinstatement
Where the package includes it, screeds, falls and tiling are reinstated by the same team.
