Fuel and Oil Tank Foam or Concrete Filling
When an oil or fuel tank can no longer be safely used — whether due to age, deterioration, or a switch away from oil-based heating — it needs to be properly decommissioned. For tanks that can’t be physically removed due to restricted access, underground positioning, or cost constraints, foam filling or concrete filling is the safest and most practical solution.
At LV Fuel Services, we carry out oil and fuel tank foam filling and concrete filling for both domestic and commercial properties across the UK. Our experienced team will assess your tank, clean it, and fill it using the most appropriate method, leaving it permanently safe and inert.
When Is Foam or Concrete Filling the Right Option for Your Oil or Fuel Tank?
The preferred approach for any redundant oil or fuel tank is to clean and remove it entirely. Where that’s possible, we offer full tank removal services for both domestic and commercial properties.
However, removal isn’t always an option. Underground fuel tanks, oil tanks in confined spaces, or tanks where excavation would be too disruptive or costly may be better suited to in-situ decommissioning. In these cases, foam or concrete filling is the recommended method — eliminating any residual fuel, flammable vapour, or explosion risk without the need for full extraction.
It’s also worth noting that in some cases, local authority or environmental regulations may require that a redundant underground tank is formally decommissioned before planning permission is granted or a property changes use. Using a professional foam or concrete filling service ensures the work is carried out correctly and can be properly documented — something that may be required by your insurer, solicitor, or local council.

RG22 Foam Filling vs Concrete Filling — What’s the Difference?
RG22 Foam Filling
RG22 is a specialist expanding foam designed specifically for oil and fuel tank decommissioning. Its capillary structure absorbs residual hydrocarbons and any remaining flammable vapours left inside the tank, rendering it permanently inert. RG22 is water-based, contains no microplastics or PFAS, and does not produce heat during application or curing — making it one of the most environmentally responsible options available for in-situ tank abandonment. Because it requires only compact equipment on site, disruption to your property is kept to a minimum, which is particularly important for domestic properties or tanks in confined or sensitive locations.
One further advantage of RG22 foam filling is reversibility. If circumstances change and the tank needs to be brought back into use, the foam can be removed and the tank cleaned and recommissioned.
Concrete Filling
Concrete filling is a permanent solution, typically used for older underground oil or fuel tanks — both steel and plastic — that will remain in situ indefinitely. Once filled, the tank is inoperable and cannot be reused. It’s a cost-effective option for in-situ tank decommissioning where no future access to the tank is anticipated.
Our team will advise which method is most appropriate based on your tank type, size, location, and plans for the site.
What to Expect — Our Foam and Concrete Filling Process
Before any filling takes place, the tank must be properly prepared. Our team will first drain any remaining fuel or heating oil, then thoroughly clean the interior of the tank to remove residual hydrocarbons, sludge, and any flammable vapour. This preparation stage is essential — filling a tank that hasn’t been properly cleaned first is unsafe and not compliant with industry best practice.
Once the tank is clean and safe, we inject the RG22 foam or introduce the concrete fill depending on the agreed method. The result is a tank that is fully inert, with no remaining explosion or contamination risk. On completion, we can provide documentation confirming the tank has been safely decommissioned — useful for insurance, conveyancing, or planning purposes.
