Why does a concrete water tank leak?

Concrete water tanks can develop leakage through cracks, construction joints, porous concrete, pipe penetrations or deteriorated waterproofing layers.

Can an existing overhead water tank be waterproofed?

Yes. An existing tank can be inspected for cracks, joint problems, surface deterioration and other leakage points before choosing a suitable waterproofing treatment.

Is waterproofing important for concrete water tanks?

Yes. Proper waterproofing can help reduce water penetration and protect the concrete structure from moisture-related deterioration when the correct compatible system is used.

Can waterproofing be applied directly over a damaged tank surface?

Damaged or weak areas generally need suitable preparation and repair before waterproofing. Applying a coating over an unstable substrate can affect adhesion and long-term performance.
