Tank & Swimming Pool Insulation
Tank and pool insulation is internal lining plus external waterproofing that stops water escaping or infiltrating and protects the concrete from corrosion. You need it for new tanks and pools, or when an existing one shows falling water levels or damp around the structure.
01
The problem
Unlined tanks and pools lose water through hairline cracks; moisture migrates into the concrete and corrodes rebar; and stored water can be contaminated by infiltrating ground or external water.
02
The solution
We inspect the structure, treat cracks and weak points, then apply the right system — internal lining with water-contact-suitable materials and external waterproofing where needed — for ground tanks, overhead tanks and swimming pools, with high efficiency and guarantee.
What does execution include?
- Inspection, surface preparation and crack treatment first
- Internal lining with water-contact-suitable materials
- External damp-proofing against groundwater where needed
- Weak-point detailing: corners, pipes, drain openings
- For ground tanks, overhead tanks and swimming pools
- Watertightness check before handover
Comparison: common tank waterproofing systems
| System | Nature | Best for |
|---|---|---|
| Flexible cementitious lining | Brush/trowel-applied coats on concrete | Ground and overhead tanks |
| Polyurea | Fast-curing heavy-duty spray membrane | Large tanks and harsh service |
| Membrane rolls | Torch-welded external rolls | External protection against groundwater |
Service FAQs
How do I know my tank needs re-insulation?
Signs include unexplained water-level drops, damp or cracks around the tank, or changed water quality. We inspect on site and specify the right treatment.
What are the steps of tank insulation?
Draining and cleaning, crack inspection and treatment, surface preparation, applying the lining system, then a watertightness check before returning to service.
