Self-Bunded Tanks: The Double-Walled Storage Solution

When it comes to safe, efficient, and environmentally responsible storage of liquids, self-bunded tanks stand out as an ideal solution for Australian industries. From fuel storage on remote job sites to chemical containment in manufacturing facilities, these double-walled tanks offer unmatched reliability while minimising the risks associated with leaks or spills. At CSG Composites, we take pride in delivering FRP (fibreglass-reinforced plastic) self-bundled tanks tailored to a wide variety of uses.

Let’s explore self-bunded tanks, how they work, and why they are such a valuable fuel storage solution across industries in Australia.

What is a Self Bunded Tank?

A self-bunded tank, often referred to as a double-walled tank, consists of two layers: an inner tank that holds the liquid and an external tank that acts as a secondary containment barrier. This innovative design eliminates the need for separate bunding structures, which are typically required for traditional single-walled tanks to prevent spills.

Self-bunded tanks are versatile and capable of storing a wide range of liquids, including diesel, petrochemical liquids, waste oil, and other hazardous materials. Unlike conventional tanks, self-bunded tanks simplify fuel management systems, reduce environmental risks, and help organisations comply with Australian standards for safe storage and transport.

Applications of Self-Bunded Tanks Across Australian Industries

1. Chemical Storage in Manufacturing

The manufacturing sector often deals with hazardous substances such as acids, solvents, or lubricants. Improper storage of these chemicals can lead to environmental contamination and operational risks.

Our FRP bunded tanks are designed to handle corrosive materials, ensuring compliance with Australian safety regulations. These storage tanks are not only resistant to chemical wear but also effective in containing large volumes of liquids.

2. Agriculture 

Australian farmers rely on self-bunded tanks to store essential liquids such as water, fertilisers, or liquid supplements. These tanks help prevent contamination risks and ensure safe handling of materials like liquid feed or agricultural oils.

For example, regional farms tend to use a bunded tank to store fertilisers, avoiding spills that could harm the environment.

3. Transport and Refuelling

In the transport industry, self-bunded fuel tanks serve as mobile refuelling stations for trucks, rail vehicles, or equipment. A self-bunded fuel tank can also be equipped with pumping systems, hoses, and connections, making them a convenient and suitable choice for logistics hubs or truck depots.

The portability of this type of fuel storage ensures that businesses can maintain petrol or diesel fuel management on-site without additional infrastructure.

4. Mining and Construction

Mining and construction sites often use self-bunded fuel tanks to store diesel and petrol for heavy machinery. In remote areas like the Pilbara or Outback Queensland, having on-site fuel storage ensures operations run smoothly without risking fuel shortages.

Self-bunded tanks are particularly useful on construction sites where space is limited. They are housed compactly, ensuring easy installation and minimal disruption to workflows.

Key Benefits of FRP Self-Bunded Tanks

Our self-bunded tanks, made from fibreglass-reinforced plastic (FRP), offer several advantages over traditional storage methods:

1. Corrosion Resistance

FRP tanks are highly resistant to corrosion, making them suitable for storing chemicals, fuel, and other hazardous substances. This durability ensures a long lifespan and reduces the need for repairs.

2. Lightweight and Space-Saving

FRP tanks are lighter than steel alternatives, simplifying installation and transportation. Their compact design optimises storage space, particularly for large volumes of liquids.

3. Environmentally Friendly

By preventing spills and minimising the need for external containment, using a self-bunded tank for pollutants like waste oil or as a fuel tank can better support environmentally responsible storage practices. The use of FRP also makes these tanks more sustainable during manufacturing and disposal.

4. Cost-Effective

The double-walled design of the tank eliminates the need for separate bunding structures or containers, reducing setup and maintenance costs. Their durability ensures fewer replacements over time, making them an effective solution for long-term storage.

Why Choose Self-Bunded Tanks for Australian Industries?

From fuel management systems on construction sites to safe storage in manufacturing facilities, self-bunded tanks are essential for Australian businesses. Their effective design, certified compliance, and robust durability make them the go-to solution for storing fuels, chemicals, and other liquids.
