A leaking underground tank wastes water, raises your bills and lets moisture into your building’s foundations — and polluted groundwater can even seep in. Water tank insulation by Arkan Prime Care seals the tank with certified materials to protect your water and your building.
When do you need tank insulation?
- Water runs out faster than usual or your water bill rises unexpectedly.
- Damp patches or white salt deposits on nearby walls.
- Visible cracks inside the tank.
- Mud or sand in the water despite regular cleaning.
- A new tank before it is first used.
Insulation types
- Epoxy: a hard, glossy, food-grade coating — ideal for drinking water.
- Fibreglass: a strong lining that covers large cracks, great for old tanks.
- Cementitious: seals the pores of the concrete; cost-effective for new tanks.
- Polyurethane: flexible and heat-resistant, for exterior and roof surfaces.
Insulation steps
- Inspection and locating leaks.
- Draining, cleaning and fully drying the tank.
- Repairing cracks and preparing the surface.
- Applying primer and insulation layers.
- Leak testing, disinfection and handover.
Benefits of insulation
- Stops leaks and saves water and money.
- Protects drinking water from contamination.
- Protects foundations from moisture and corrosion.
- Smoother surfaces that are easier to clean.
Keep your tank in top condition with regular water tank cleaning.
