Decommissioning, Foam and
Concrete Filling
Rendering Used Tanks Safe and Environmentally Stable.
At some point, your Commercial Fuel Oil tank will reach the end of its useful, environmentally safe life. In some cases this will be because it is no longer structurally safe, or it could be because you have chosen to replace the heating systems for which it is providing oil with something more environmentally friendly.
In both cases you will need to decommission the tank safely or remove it altogether. If, for any reason, your tank cannot be cleaned and physically removed from its installed location, our experienced OFTEC trained team can render it safe and environmentally stable.
Oil tank decommissioning involves the safe and proper removal of an oil storage tank that is no longer in use. This process is necessary to prevent any potential environmental hazards that may occur due to a leaking or deteriorating tank.
Foam filling is a method used to decommission an oil tank by filling the tank with an expanding foam material. The foam is injected into the tank through a small opening, and it expands to fill the entire space inside the tank, effectively sealing it off from the outside environment. The foam material used is usually a polyurethane foam that hardens and becomes solid after it expands.
Concrete filling is another method used to decommission an oil tank. In this process, the tank is drained of any remaining oil and cleaned thoroughly. Then, a hole is cut into the tank’s top, and a concrete slurry mixture is poured into the tank until it is completely filled. The concrete mixture is allowed to set and harden, effectively sealing the tank and preventing any oil or other contaminants from escaping.
Both foam filling and concrete filling methods are effective at decommissioning oil tanks, and the choice between the two usually depends on the specific requirements of the site and the tank. It is important to use a professional and experienced contractor to carry out the decommissioning process to ensure it is done safely and in compliance with all relevant regulations and standards.
Foam Filling and Concrete Filling
RG22 foam for fuel tank foam filling is generally the best option and renders your fuel tank inert. RG22 foam is designed to absorb hydrocarbons that are left inside the tank, improving safety and reducing the risk of hazardous material emissions.
RG22 also provides additional flexibility in case you decide to reuse your fuel tank in the future, the RG22 foam can be removed and the tank can be cleaned and put back into use.
It’s also possible to fill your unused fuel tank with concrete. After concrete filling, the tank will be rendered inoperable forever, meaning it can’t be used again.
Concrete is used as a permanent filling option for older commercial and domestic fuel tanks that will stay in the ground.
Avoiding Inconvenience and Unnecessary Costs.
Both of these processes result in your old, unused oil tank being made safe, with any of the remaining traces of flammable gases or explosive vapour removed and made inert. This allows you to easily switch from oil-based heating to another system, all without the costs or inconvenience of having your existing fuel tank completely removed.
Removing and Recycling Old Oil Tanks
Alternatively, if you no longer need an oil tank, it can be removed, disassembled and recycled in an environmentally sustainable way and its materials used to produce new products. This is our commercial focus and we offer certificates of disposal to confirm that any plastic tanks are shredded on our site, and steel tanks are cut into pieces and subsequently recycled.
As specialists in domestic oil tanks, we’re highly experienced for whenever you might need a professional service tank filling, removal and a range of other services.
