Tank Waterproofing

A water tank must safely store water without leakage or contamination. Over time, cracks in walls, improper coving at corners, and gaps around pipe joints can lead to water seepage, structural damage, and loss of stored water. Leakage not only weakens the tank but can also affect the roof and surrounding building structure.

Our water tank waterproofing solutions focus on sealing every vulnerable area using advanced materials and proven techniques. We repair structural cracks, construct proper coving at sharp corners, and seal pipe penetrations effectively to prevent leaks.

With CFTRI-approved coatings suitable for potable water storage, we ensure safe, hygienic, and long-lasting protection for your water tanks.

Cracks In The Walls

Concrete and brick water tanks naturally develop cracks as they age. These cracks become entry points for water leakage, allowing moisture to escape from the tank. Over time, continuous exposure to moisture can corrode the steel reinforcements within the concrete, weakening the overall structure and compromising its safety. With advanced waterproofing treatments, these cracks are properly sealed and reinforced, effectively stopping leakage and protecting the structural integrity of the tank for the long term.

Absence Of Coving

Coving refers to the smooth curved finish provided at the internal corners of a water tank. Sharp 90-degree angles are highly vulnerable to leakage, as they create stress points where cracks and seepage can develop over time. If proper coving is not incorporated during construction, the risk of water leakage increases significantly. The effective solution is to form a proper coving at all corners and apply a durable waterproof coating to the internal surfaces, ensuring long-term leak protection.

Pipe Joints

Water tanks are connected to inlet, outlet, and discharge pipes that pass through the tank walls. Since these pipes are typically made of PVC or metal, they do not naturally bond with concrete. As the concrete cures and gradually shrinks over time, small gaps can form around these pipe penetrations, creating pathways for leakage. To eliminate this issue, we seal these vulnerable joints using high-performance double-sided bitumen tapes and specialized waterproofing materials, ensuring a tight seal and long-term protection against water seepage.

Core Services

Our water tank waterproofing services provide complete internal protection to ensure safe and leak-proof water storage. We apply CFTRI-approved potable waterproof coatings that are safe for drinking and cooking purposes. Our process includes detailed inspection, crack repair, and structural sealing to prevent moisture penetration and reinforcement corrosion. We construct proper coving at tank corners to eliminate sharp angles and reduce leakage risks. In addition, we seal inlet, outlet, and discharge pipe joints using high-performance bitumen tapes and waterproof sealants, while also protecting the surrounding roof slab from seepage damage. Our comprehensive approach ensures long-lasting durability, hygiene, and structural safety for your water tanks.
