Custom Fibreglass Tanks & Repairs – Built to Last, Made for You

Looking for a tough, reliable tank that won’t rust, crack or give you headaches in a few years? You’re in the right place.

At Fibreglass Sydney, we’ve been building, customising, and repairing fibreglass tanks for over 35 years. Whether you need something small for your backyard or a large tank for industrial, transport, or religious use – we can build it your way.

We take care of everything from design to delivery. And if you’ve got a tank that’s leaking, worn out or needs a new life, we can fix that too.

Why Fibreglass Tanks?

Fibreglass tanks (also called FRP tanks) have become a go-to choice across all sorts of industries – and it’s easy to see why.

So if you’re tired of settling for off-the-shelf plastic or metal tanks that just don’t fit – fibreglass is the smart way to go.

We Custom-Make Your Tank – Any Size, Any Shape

Every project is different. That’s why we don’t just sell tanks – we build them.

Whether you need a sleek transport tank for moving liquids, a large clarifier tank for your treatment plant, or even a one-of-a-kind baptismal tank for your church community – we can help.

We Customise:

We work with you from the idea stage all the way to final delivery. It’s what we’ve done for over three decades.

Tank Types We Build

Here’s just a snapshot of the fibreglass tanks we make for customers across NSW and beyond:

Water Storage Tanks

For homes, farms, and commercial buildings. Great for rainwater harvesting, irrigation, or even drinking water (we use potable-grade materials on request).

Chemical Storage Tanks

Built to safely handle acids, alkalis, and other harsh chemicals. Ideal for mining, agriculture, and wastewater treatment.

Transport Tanks

Need to move liquids safely? We build fibreglass tanks for trailers, trucks, and utes – ideal for fuel, chemicals, water, or fertiliser. Designed for road transport, vibration resistance, and secure mounting.

Baptismal Tanks

We custom-build fibreglass baptismal tanks for churches, religious centres, and personal use. Stylish, easy to clean, and made to suit indoor or outdoor spaces.

Clarifier Tanks

Used in water treatment plants and industrial settings to separate solids from liquids. Strong, corrosion-resistant and designed for long-term performance.

Kit Form Tanks

Need your tank delivered in sections and assembled on site? Our kit-form fibreglass tanks are great for remote locations, tight access areas, or export shipping.

Underground Tanks

Discreet, space-saving and built tough. We build tanks that can go underground without compromising strength or leak resistance.

Diesel & Fuel Tanks

Secure and safe for fuel storage. Anti-static, sealed, and compliant with Australian safety standards.

Aquaculture Tanks

Smooth, food-grade tanks ideal for fish hatcheries, shrimp farms and marine research.

Fire Water Tanks

High-capacity tanks for firefighting systems or bushfire safety. Compliant and built for emergency use.

Mixing & Processing Tanks

Used in food production, chemical batching, and more. We can add mixers, baffles or other features based on your operation.

Custom Moulded Tanks

Got a special design or product in mind? We can create one-off moulds or repeat-use moulds for tank production. Ideal for OEMs, manufacturers, and niche industries.
