Tank Waterproofing

Tank Waterproofing

A leaking vessel doesn’t serve its purpose. In the same way a water tank that leaks cannot hold water for long. In addition, the water that leaks from the tank also causes damage to the roof of the building. Tank waterproofing is a critical activity that doesn’t just preserve water but also protects your building.


None of the cement tanks are good to store potable water. Our coatings are approved by CFTRI for storing potable water, which means that you can use this water even for cooking purposes after we waterproof your tanks.


Because of the constant pressure from the water inside and due to age, water tanks develop a lot of issues that result in leakage of water. The following are the most common reasons why your tanks start to leak.

Cracks In The Walls

Both concrete and brick tanks develop cracks over the years. Water starts leaking through these cracks. As time progresses the moisture corrodes the metal reinforcements inside the concrete causing danger to the structure itself. Modern waterproofing solutions ensure filling of cracks and prevention of water leakage.


Absence Of Coving

Coving is the curve provided at the corners of the tanks. All sharp angles can cause water leakage and this is the reason for the coving. If this is not done during construction of the tank, water leakage is very likely. The solution is to construct the coving and provide waterproof coating to the inside walls.


Pipe Joints

There are inlet, outlet and discharge pipes that connect the tank to the outside. Pipes are made of either PVC or metal and both these materials don’t bond with concrete. This makes it highly likely that gaps appear where the pipes pass through the tank walls as concrete shrinks over time. We use double-sided bitumen tapes to seal the gaps and stop the leaks forever.
