A concrete pool shell holds tonnes of water under constant pressure, and the surrounding coping, paving and adjoining structures are exposed to splashing and chlorinated water. Without a suitable tanking membrane, water can leach through the shell, stain surrounding walls and damage finishes.
We waterproof new and renovated concrete pools, spas, ponds and water features, as well as the pool surrounds and structures built next to them.
Signs you need swimming pool waterproofing
- Water level dropping faster than evaporation
- Tiles lifting or grout washing out
- Damp or efflorescence on walls near the pool
- Cracks in the pool shell or coping
- Wet areas in the garden near the pool
- Rust stains from reinforcement
Pool waterproofing systems
Pool waterproofing is different from a bathroom or balcony: the membrane must remain permanently submerged, resist chlorinated or salt water and bond under the tile adhesive. We use cementitious and polymer-modified tanking systems specifically designed for immersion.
What we waterproof
- Concrete pool and spa shells before tiling
- Water features, ponds and fountains
- Pool surrounds, coping and adjoining retaining walls
- Rooftop and podium pools (with the building membrane)
- Balance tanks and plant rooms
Leak investigation
Before any work, a pool leak should be confirmed with a bucket test or specialist leak detection to rule out plumbing and equipment. We then address cracks, joints and failed surfaces with injection and tanking systems as required.
Our swimming pool waterproofing process
-
1
Assessment
We confirm the leak or scope, inspect the shell and review the finishes.
-
