How to fix a leaking water tank?
The typical lifespan of a concrete water tank is 20 to 25 years. But in its solidified state, the concrete is a heterogeneous substance containing spaces and capillaries inside its matrix. It is therefore quite likely that water leaks in through these gaps and capillaries.
Managing the issue of water tank leaks may be somewhat difficult. It goes without saying that this is one of the items that, if ignored, might exacerbate the water leak issue. Water leaks can enter via the base of the water tank’s fissures and go through the roof to the interior walls and ceiling.

It’s critical to comprehend and address the underlying cause of the water tank leak in order to resolve it. The age of the water tank itself might be one of the causes. Water leaking from the tank’s interior, most likely the base, is another option. If you are already aware of the leak’s cause, this will enable you to successfully address it.
To better comprehend the issue of leaks in concrete water tanks, let’s take a closer look.
Potential causes of water leaks
Note: Concrete water tanks require special attention throughout the construction process since they are an essential component of any building. By doing this, seepage and water pollution may be avoided.
Water leaks are typically the result of poorly treated joints and excessive porosity that cannot withstand water pressure after a few years of construction.
Concrete water tanks are susceptible to leaks because of the impact of fluctuating water pressure on their walls, which can lead to structural movement and cracks.
Agencies that contribute to the leaking issue
Note: Ensuring that the concrete water tank is precisely made to function well in withstanding variable hydrostatic water pressure is one of the logical strategies to prevent the problem of water leaking.
Having stated that, let’s examine a few continuing behaviors that contribute to the issue of leaky water tanks.
Poor material and craftsmanship are major concerns that lead to the leaking issue. Masons do not add any chemicals to the cement, which eventually causes the entire tank’s structure to have too many pores because of the continuous water pressure.
Homeowners or even construction managers frequently neglect to provide the water tank the proper care. The tank requires particular treatment because it will be holding a sizable amount of water. Regarding the existing procedure, they only apply a coat of plain cement slurry that has been combined with latex or acrylic polymer, none of which is elastomeric nor water-resistant. Consequently, the therapy is ineffective and fails to function in the face of an ongoing water attack.
Typically, the inside walls of concrete tanks are coated with tiles, which have the potential to develop fungus and algae over time. As a result, pollutants pollute the water and may cause health issues if consumed.
The exterior walls of water tanks, both aboveground and below, are another overlooked feature. Supervisors of construction projects frequently neglect outside walls or use cement polymer slurry, which is unable to offer the necessary defense against contaminated groundwater and soil. Furthermore, the treatment’s ability to maintain groundwater pressure is ineffective.
Another main cause of likely leaks is poorly sealed gaps in the concrete water tanks’ walls.
Correctives for improper behavior
Poor-grade concrete
To minimize water permeability during the concrete-making process, a waterproofing compound needs to be combined. We are the perfect option for this situation. It works very well at minimizing pores and honeycombing, which helps to lessen the issue of water seepage.
Ineffective interior wall protection layer
Whether the concrete water tanks are subterranean or above, the inside walls must be coated with a polymer-modified cement coating that has been authorized for food grade coating. We are the best option for handling this sort of issue. It is a cementitious coating with acrylic modifications that is extremely elastic, offers a 1 mm protective layer, and functions well with different water pressures.
A inadequate layer of protection on the outside walls
The external walls need to be coated with coal tar to solve this issue. You may think of our excellent solution as a defense against groundwater and soil pollution for exterior walls. There is no longer any possibility of water seeping through the walls because to the chemical’s excellent water resistance.
Inadequately sealed gaps because of plumbing pipes
Every hole has a gap that has to be appropriately sealed. You could think about wrapping around plumbing pipes as a solution to this issue. The gaps can then be filed after this. It is an expansive cementitious material that does not shrink and serves as a powerful barrier to keep out water.
Lastly
You need to select the best waterproofing solution for your leaky water tank in order to complete the task correctly and be certain of a long-lasting cure.
