Swimming Pool Waterproofing
Pools are under constant water exposure, so the membrane system has to handle continuous pressure, not occasional rain.
Typical Symptoms
How this usually shows up
- Leakage visible in adjacent areas or rooms below
- Unexplained drop in pool water level
- Cracking near the pool deck or coping
- Damp patches on the pool's structural walls
Common Causes
What's usually behind it
- Cracked pool shell or structural joints
- Failed waterproofing membrane
- Pipe or fitting leaks within the structure
- Deteriorated expansion joints
Treatments We Apply
The right treatment depends on substrate, severity, and exposure — determined during assessment.
Liquid-Applied Membranes
Crystalline Waterproofing
Expansion Joint Treatment
PU Injection Grouting
Our Process
We pressure-test to isolate structural vs. plumbing leaks, then apply a continuous positive-pressure membrane system built for constant water contact.
