Water tank waterproofing in Lahore that stops leaks and water loss.
Capital Waterproofing seals underground and overhead water tanks in houses, apartments, plazas and factories. We find where the tank leaks first, then repair and waterproof it so stored water stays in and dirt stays out.
Signs your water tank is leaking
A leaking tank wastes water, damages the structure around it and can let dirt into your stored water.
- Water level drops even when the water is not being used
- Damp or wet patches around the tank walls or floor
- Cracks or seepage on the tank walls
- Damp on the ceiling or wall near an overhead tank
- Stored water looks or smells dirty
- Peeling or flaking coating inside the tank
Send us a photo of the tank on WhatsApp and we will tell you what is likely happening.
Why water tanks leak, and how we fix it
After the inspection we recommend the method that suits your tank, where it leaks and your budget.
Cracks and joints
Cracks in the walls and floor, and the joints between them, let water out and groundwater in. We repair and seal them.
Pipe and outlet points
Gaps around inlet, outlet and overflow pipes are common weak spots. We seal them carefully.
The waterproof lining
We apply a waterproofing system suited to water storage, and protect the outside surfaces where needed.
