Water tanks are essential for industrial operations, commercial facilities, and fire protection systems. But even the strongest tanks degrade over time. Without proper refurbishment, minor issues can escalate into leaks, contamination, or complete structural failure.
At Tank Liners Melbourne by Raven Tanks Australia, we help property managers, engineers, and facility owners identify early warning signs and restore their tanks before costly damage occurs.
Visible Corrosion or Rust
Corrosion is one of the most common and serious signs that your tank needs refurbishment.
When rust appears on the roof, joints, or walls, it indicates the protective coating has failed.
If ignored, corrosion spreads rapidly, weakening the tank’s structure and causing leaks.
Refurbishment typically involves cleaning, sandblasting, and recoating the interior or exterior surfaces with protective linings such as PVC or epoxy — preventing further deterioration and extending the tank’s lifespan.
Leaks and Water Stains Around the Base
Pooled water or damp areas surrounding the tank are a strong indicator of internal leaks. These are often caused by small cracks, corroded bolts, or liner damage. Over time, even minor leaks can erode foundations or contaminate stored water.
A professional inspection can pinpoint the source, and refurbishment — including seal replacement and liner repair — restores watertight integrity.
Structural Deformation or Sagging Roof
If your tank walls appear distorted or the roof is sagging, it’s time for immediate attention.
Deformation signals internal pressure imbalance, corrosion of supports, or general fatigue of materials.
Ignoring this issue can compromise the entire tank structure, posing safety and compliance risks.
Tank Liners Melbourne by Raven Tanks Australia performs detailed structural tank assessments to determine if refurbishment or reinforcement is required.
Damaged or Aging Liners
A tank’s internal liner prevents corrosion and contamination. However, over years of exposure, liners can peel, crack, or delaminate from the surface. Once that happens, corrosion begins almost immediately underneath.
Water tank repair with a new PVC, HDPE, or butyl liner restores watertight protection and ensures compliance with Australian standards for potable and fire water systems.
Contaminated or Discoloured Water
If the water inside your tank looks cloudy, smells metallic, or changes colour, internal corrosion may be to blame. Rust particles and bacterial buildup can quickly compromise water quality.
A thorough water tank repair — including cleaning, relining, and disinfection — removes contaminants and restores safe storage conditions.
Rising Maintenance Costs
Frequent small repairs often signal a deeper problem. Instead of continuous patchwork, a full refurbishment can be more cost-effective and extend your tank’s usable life by 10–20 years.
This is particularly important for fire protection systems in Melbourne, where reliability and compliance with AS1851 standards are critical.
Why Timely Refurbishment Matters
Postponing refurbishment can lead to severe structural failure, water loss, and safety hazards.
A proactive maintenance plan ensures your tank remains compliant, efficient, and ready to perform when needed.
Refurbishment also supports sustainability — extending the tank’s life rather than replacing it entirely.
