At Sweetwater Tank Cleaning, we specialise in concrete water tank repairs for rural and domestic properties across Tamworth, Moree, Glen Innes, Walcha, Muswellbrook, and Coonamble. Based in Duri, NSW, our family-run business has over 20 years of experience in tank cleaning and maintenance. We provide professional repair solutions that extend the life of your water tanks and protect the quality of your stored water.

 

Concrete tanks are built to last, but exposure to weather, movement, and water pressure can cause cracks or leaks over time. When left untreated, these issues can worsen, leading to water loss, contamination, or structural damage. Our experienced technicians use proven methods and specialised products to restore the integrity of your tank, ensuring it remains watertight and reliable for years to come.

How to Tell if You Need Water Tank Repairs

Concrete tanks often show early signs of wear that should not be ignored. The most common indicator of a leak is unusual dampness or lush plant growth around the base of your tank. This can occur when water seeps through cracks in the concrete. You may also notice that your water level is dropping faster than usual, even when there has been little or no use.

 

Changes in water appearance, taste, or odour can also signal that your tank needs attention. Cracks and leaks can allow contaminants or soil to enter the water, affecting quality. Addressing these signs early prevents further damage and avoids costly repairs in the future.

Our Concrete Tank Repair Process

Our team follows a thorough and reliable process for every tank repair. We start by draining the tank to locate cracks, leaks, or areas of damage. Once the tank surface is clean and dry, we prepare the affected areas for sealing. Using a specialised epoxy-based product, we carefully fill and seal each crack to ensure a complete, watertight finish.

 

This epoxy forms a durable bond that restores the tank’s structure and prevents further leakage. After curing, your tank is ready to be refilled and put back into use. Our proven repair techniques are trusted by homeowners, farmers, and rural businesses throughout the Tamworth region.

Specialised Epoxy Products for Safe Repairs

We use high-quality, food-grade epoxy products that are safe for potable water tanks. These materials are resistant to wear and corrosion, ensuring the water quality inside your tank is not affected during or after repairs.

Installing New Tank Liners for Long-Term Protection

For older or heavily damaged tanks, we also offer new tank liners to create a completely waterproof barrier inside the tank. Liners are ideal for preventing future leaks, sealing small hairline cracks, and extending the life of your tank without the need for full replacement.

 

We apply a durable, waterproof membrane to the tank’s interior that prevents seepage and reinforces the structure. This additional protection is perfect for older concrete tanks that have experienced long-term wear. Installing a liner is a cost-effective way to preserve your water storage and avoid more extensive structural repairs in the future.

Concrete Water Tank Repair FAQs

  • How do I know if my concrete tank is leaking?

    Look for damp soil, greener grass, or moss growing around the base of the tank. These can all indicate water leakage. You may also notice a sudden drop in your water level or discolouration in the stored water.

  • Can you repair large cracks in concrete tanks?

    Yes. We use a specialised epoxy-based sealant that can repair both small and large cracks. The product creates a durable, watertight seal designed to last for years.

  • Is it safe to use the water after repairs?

    Absolutely. We only use materials approved for potable water systems, meaning the repairs will not affect the safety or quality of your water.

  • When should I consider installing a new tank liner?

    If your concrete tank has multiple cracks, ongoing leaks, or is showing signs of significant wear, installing a liner can provide long-term protection. It prevents further leaks and extends the lifespan of your tank.
