Bunded Fuel Tanks in the Construction Industry

The Importance of Bunded Fuel Tanks in the Construction Industry

Construction sites run on fuel, diggers, generators, site cabins and welfare units all need a reliable supply, and running to a garage every day isn’t practical when a site might be miles from the nearest forecourt. That’s why on-site bunded fuel tanks have become standard kit on UK construction sites, and increasingly a requirement rather than a nice-to-have.

Why bunding matters on a construction site

A bunded tank is built with a tank inside a tank: the inner vessel holds the fuel, and the outer bund catches anything that escapes if the inner tank is ever damaged or leaks. On a site with heavy plant moving around, accidental knocks are a real risk, and a spill that reaches open ground or a drain can mean a costly environmental clean-up and a call from the Environment Agency. See our bunded fuel tank regulations guide for exactly when the law requires this.

Site safety and fire risk

Fuel stored in the open is also a fire risk. Bunded tanks are built with fire safety in mind, flame arresters, vents and, on our tanks, 43A steel construction that holds up to knocks far better than plastic. That matters when a tank is sharing a site with welding, cutting and other hot works.

Fewer trips off-site, more uptime

Beyond compliance, an on-site tank keeps plant fuelled without sending a van off-site every day, worth factoring in alongside straight fuel cost when you’re pricing up a project. Our guide to bunded fuel tank costs breaks down what a tank like this typically costs to buy and run.

Built for site conditions

We build tanks specifically for construction use: lockable cabinets to deter tampering and theft (a genuine risk on unattended sites), forklift pockets and lifting eyes for moving between locations as a project progresses, and sizes to suit anything from a small groundworks job to a major infrastructure site. Have a look at our Construction & Plants industry page for the full range, or get in touch and we’ll help you size the right tank for your site.
