Water tank liners are essential for maintaining the hygiene, safety, and structural integrity of industrial and commercial water tanks. Over time, even the most durable liners – PVC, EPDM, or reinforced polymers—can degrade due to UV exposure, chemical reactions, or mechanical damage.
If your liner is leaking, bubbling, or tearing, water tank liner repairs are crucial to restore function, protect stored contents, and help you avoid costly downtime or replacements.
Warning Signs of a Damaged Tank Liner
- Leaks or seepage around seams or at the tank base
- Visible tears, cracks, or blisters on liner surfaces
- Discoloration or delamination (especially in food-grade tanks)
- Increased water loss or pressure changes in your system
- Foul odors or signs of bacterial contamination
Early detection of liner damage can save thousands in repairs and regulatory fines.

Repair vs. Replacement: what’s Right for You?
If your liner damage is isolated and your tank structure is intact, repairs can extend its lifespan by 5–10 years. However, if the liner is more than 10 years old or damage is widespread, a full tank liner replacement may be more cost-effective and compliant with Australian safety standards.
Need help deciding? We offer free inspections and consultations across Australia.

Delaying liner repairs can result in:
- Water contamination or loss
- Tank corrosion and structural failure
