Reliable Water Tank Waterproofing Services by Waterseal
Water tank waterproofing is a crucial step in maintaining the structural integrity and hygiene of any building. Whether it's a residential, commercial, or industrial property, water tanks—especially underground or overhead tanks—are prone to seepage, cracks, and leakages over time. These issues can lead to serious problems, including damage to the surrounding structure, foul smells, and the growth of harmful bacteria such as algae and fungi. That's why choosing the right waterproofing method is essential, and Waterseal is the name you can trust.

We understand the climate, water conditions, and construction challenges of Gujarat better than anyone.
Our years of experience enable us to suggest customised solutions depending on the tank’s location, age, structure, and usage. From internal tank linings to flexible coatings and crack-sealing compounds, we use scientifically proven waterproofing systems to ensure long-lasting results.

Why Is Water Tank Waterproofing Important?
Concrete is naturally porous and becomes prone to cracks with time. These cracks allow water seepage, which not only damages the tank structure but also creates health hazards. Leakage from water tanks can:
Damage interior walls and ceilings
Cause foul smells
Promote the growth of fungi and algae
Contaminate drinking water
Spread water-borne diseases
Waterseal understands the seriousness of this issue and offers safe, effective, and hygienic water tank waterproofing solutions. Our products are safe for drinking water and meet all necessary health standards.
Underground Water Tank Waterproofing Solutions
We specialize in underground tank waterproofing, where internal leakage often goes unnoticed until the damage is severe. Our solution involves applying a silicone polymeric waterproofing compound, which forms a tough, elastic, and long-lasting barrier inside the tank. This material is non-toxic, chemical-resistant, and 100% safe for potable water.
Our building care engineers inspect the tank thoroughly and suggest a customized waterproofing treatment based on the condition of the concrete, the presence of cracks, moisture levels, and the tank’s use (drinking water, gardening, or industrial usage). The entire waterproofing process is completed within a scheduled timeline with minimum inconvenience.
Overhead Water Tank Waterproofing
Overhead tanks face constant exposure to heat, UV rays, and seasonal expansion-contraction cycles. These environmental factors cause hairline cracks and joint failures, which eventually lead to leakage. Waterseal's PSv Premix Waterproofing System is ideal for such tanks. It seals all hairline cracks, reinforces weak spots, and creates a smooth, algae-free tank lining.
Our PSv Premix chemical is a ready-to-use, non-shrink, anti-fungal waterproofing compound that protects your tank and ensures that your stored water remains clean and safe.

Common Questions About Water Tank Waterproofing Solutions
How can I stop water leakage from my overhead tank?
To stop water leakage from an overhead tank, clean the surface properly and repair any visible cracks. Then, apply a high-quality waterproofing chemical like Waterseal PSv-PREMIX using a brush or roller. Allow it to cure fully before refilling the tank.

For long-lasting protection, Waterseal PSv-PREMIX is ideal. It is a ready-to-use, flexible waterproofing compound specially formulated for RCC water tanks, underground tanks, and plastic tanks. It requires no mixing with white cement.

Yes, DIY waterproofing is possible with Waterseal PSv-PREMIX. Just mix it with an equal part of water and apply it directly to the tank surface in two coats. It saves money and gives professional results without hiring a contractor.
