Preventing water leakage in tanks is a critical concern for storage facilities and industries. To address the issue, a range of chemicals and coatings have been marketed, each with its unique characteristics and applications. Prevent water wastage and property damage with our expert solutions for fixing leaking water tanks. These materials protect structures from leaks, corrosion, and deterioration, keeping the tank’s longevity intact. In this blog, we will explore some of the key chemicals that are used to prevent leakage in tanks.

Polyurethane Coatings
Polyurethane coatings are recognized for their exceptional adhesion, flexibility, and resistance to moisture. These coatings form a seamless and durable layer on tank surfaces, effectively preventing water leakage by providing a watertight seal that withstands various environmental conditions, including temperature fluctuations and exposure to chemicals.
Polyurethane coatings are applied on a variety of tank types, including water-storage, chemical, and industrial tanks. Their versatility, adhesion, and UV-resistance make them suitable for interior and exterior applications. Additionally, polyurethane coatings can be customized to accommodate specific tank requirements, ensuring optimal protection against water leakage.

Epoxy Coatings
Epoxy coatings offer excellent chemical resistance and bondage together with proper sealing (without loose edges). Moreover, these coverings are suitable for tanks that carry corrosive substances or stay in contact with chemicals.
-
Acrylic Coatings
Acrylic coatings are known for creating a water-resistant and protective film on tank surfaces. These coatings form a flexible barrier that prevents water leakage while allowing the substrate to breathe, reducing the risk of trapped moisture. Acrylic coatings are applied on surfaces where balance between water resistance and breathability is mandatory.
Acrylic coatings are applied to safe-keep boundaries from rusting and deterioration: Their UV resistance and color retention properties also contribute to maintaining the appearance of tanks over time.
-
Rubberized Coatings
Rubberized coatings, mostly formulated with elastomeric materials, provide an effective solution for preventing water leakage. These coatings can stretch and contract with the substrate, accommodating movements caused by temperature changes. As a result, they maintain a secure seal even under dynamic conditions.
Rubberized coatings are ideal for tanks subjected to frequent temperature fluctuations or structural movements. They are applied to roofs of water storage tanks, as well as tanks installed in seismic-prone areas. The elasticity of rubberized coatings helps to seal tank surfaces regardless of external factors.

Bituminous Coatings
Bituminous coatings, also known as asphalt coatings, are used for waterproofing underground and concrete tanks. These coatings are derived from bitumen—a hydrocarbon material that offer supreme resistance to moisture.
Causes of Water Tank Leakage
- Corrosion, often caused by the interaction between the tank’s material and water, weakens the structure over time, leading to cracks and holes.
- Poor construction or inadequate sealing during installation can result in leakage during use.
- Physical damage from external sources, such as impacts or seismic activity, can compromise the tank’s integrity.
- Temperature fluctuations may cause expansion and contraction, contributing to cracks.
- Sediment buildup or mineral deposits on the interior can erode the tank, creating openings.
- Regular maintenance, quality materials, and proper design are crucial to mitigate water leakage in tanks.
Conclusion
Preventing water leakage in tanks is a crucial consideration to maintain the functionality and integrity of these structures. Various chemicals and coatings, including polyurethane, epoxy, acrylic, rubberized, and bituminous coatings, offer effective solutions to address this challenge. The choice of the most suitable chemical or coating depends on factors such as the tank’s purpose, the substances it stores, environmental conditions, and budget constraints. By applying the appropriate protection, industries can ensure that their tanks remain leak-free, durable, and capable of withstanding the demands of their applications.
