Your water tank supplies your family’s drinking and household water. Cracks or leaks waste water, raise bills and let dust, insects and bacteria in. Tank waterproofing keeps your water clean and your building safe.
Food-grade epoxy lining
We line tanks with food-grade epoxy designed for potable water. It forms a smooth, solid surface that stops leaks, prevents bacteria and algae, and makes future cleaning easy.
Tanks we waterproof
- Underground concrete tanks (epoxy inside, bitumen outside on new builds).
- Roof tanks — leak and crack repair.
- Large tanks for commercial buildings and compounds.
Our process
- Drain and fully clean the tank.
- Dry and sand the surfaces.
- Repair cracks and pipe penetrations.
- Apply primer and food-grade epoxy coats.
- Full cure, then wash and disinfect before refilling.
We also offer tank cleaning and disinfection. To stop leaks indoors, see bathroom waterproofing, or book a free inspection.
