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.
Underground Tank Foam and Concrete Filling
For tanks that cannot be safely or economically removed, foam filling underground tanks and concrete filling underground tanks provide practical methods of decommissioning them in situ.
The most suitable method will depend on the tank’s condition, location and future use of the site. Where excavating fuel tanks is not practical, filling the tank can offer a permanent alternative to full removal.
When Is Foam or Concrete Filling the Right Option for Your Oil or Fuel Tank?
Where practical, the preferred approach for a redundant oil or fuel tank is to clean and remove it completely.
However, excavating fuel tanks is not always possible or commercially sensible, particularly when a tank is beneath a building, driveway, forecourt or other permanent structure.
Where excavation would cause excessive disruption, create additional environmental risks or involve disproportionate costs, the tank may instead be cleaned and decommissioned in situ using specialist foam or concrete.
This eliminates 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 be 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.
Void Filling Services — Sinkholes, Mine Shafts & Redundant Structures
Beyond fuel tank work, our foam and concrete filling service covers a wide range of void filling applications across domestic, commercial, and civil engineering sites. If you have an underground void, redundant structure, or an area of ground that’s become unstable, we can assess and fill it safely.
Sinkhole Filling & Sinkhole Remediation
Sinkholes pose a serious safety and structural risk, particularly on development sites, agricultural land, and near ageing drainage infrastructure.
We provide sinkhole filling and sinkhole remediation using expanding polyurethane foam or pumped concrete grout, depending on the size and depth of the void.
The material is injected to fill the cavity fully, stabilise the surrounding ground, and prevent further collapse.
If you’re dealing with ground subsidence or a confirmed sinkhole on your property, early intervention is key.
We can mobilise quickly and provide a written assessment of the works carried out.
Mine Shaft Capping & Shaft Decommissioning
Old mine shafts and abandoned shaft workings are a hazard on many sites across the UK — often unrecorded and only discovered during development groundworks.
We offer mine shaft capping and full shaft decommissioning using foam or concrete filling, in compliance with relevant guidance from the Coal Authority and local planning requirements.
The cost of capping a mine shaft varies depending on depth, diameter, and access.
We’ll carry out a site visit and provide a detailed, fixed-price quotation before any work begins.
All works are documented and reported for planning and insurance purposes.
Swimming Pool Decommissioning
Redundant swimming pools — particularly older in-ground pools at residential and commercial properties — are often more cost-effective to decommission than to maintain or demolish.
We fill redundant pools with expanding foam or concrete, depending on the structure and your intended use for the site afterwards.
Foam filling is particularly effective for this application as it’s lightweight and won’t place excessive load on the surrounding ground.
It’s increasingly popular ahead of garden landscaping projects and property sales where maintaining a disused pool is a liability.
Other Void Filling Applications
We work across a broad range of underground void filling projects, including:
- Cellar and basement void filling
- Road void filling and emergency road subsidence repair
- Culvert decommissioning
- Well decommissioning and capping
- Cavity filling beneath buildings and infrastructure
- Bridge and wharf void injection
- Quay wall stabilisation
- Underground structure stabilisation

Contaminated Land Remediation & Groundwater Protection
Foam and concrete filling plays an important role in contaminated land remediation — particularly where redundant tanks, pipelines, or underground structures are a source of ongoing environmental risk.
By filling and inert-sealing the vessel, you remove the pathway for further leakage and support the wider remediation of the site.
Tank Filling as Part of Contaminated Land Treatment
Where a leaking or corroded tank has already caused contamination, or where there’s a risk of future leakage into surrounding soil and groundwater, foam or concrete filling is often required as part of a formal contaminated land treatment programme.
This permanently renders the tank inert and eliminates it as an ongoing pollution source.
We work alongside environmental consultants, site investigators, and remediation contractors and can provide site-specific method statements, RAMS, and completion records to support your documentation.
Groundwater Protection
Old or leaking underground storage tanks (USTs) near water courses, boreholes, or Source Protection Zones (SPZs) present a significant risk to groundwater quality.
Filling the tank completely eliminates the void and removes the capacity to hold or accumulate product.
We’re experienced in working on sites subject to groundwater protection regulations and can liaise with the Environment Agency where formal notification or approval is required.
Hazardous Material Containment
Where a tank has previously held hazardous materials — including chemicals, waste oils, or contaminated fuel — foam or concrete filling provides a cost-effective method of permanent containment.
The fill material encapsulates any residual contamination and prevents it migrating into the surrounding environment.
All works involving hazardous materials are carried out with full COSHH assessment, appropriate PPE and site controls, and waste disposal documentation.
Site Redevelopment Preparation
Whether you’re preparing a brownfield site for planning, selling a commercial property, or handing back a leased site, in-ground tanks and pipelines often need to be formally decommissioned and filled before sign-off.
We issue a completion certificate for all foam and concrete filling works, which can be used to satisfy solicitor, insurer, and planning requirements.
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.
Pipeline Decommissioning & Redundant Pipework Filling
Redundant pipelines and service pipes present many of the same risks as disused tanks — structural collapse, contamination pathways, and future liability.
We offer foam and concrete filling for a wide range of decommissioned pipework, from domestic service pipes to large commercial and industrial pipelines.
Gas Pipework Decommissioning
Decommissioning gas pipework that’s no longer in service often requires the pipe to be purged, pressure-tested, and then filled or sealed to prevent future use or accidental reconnection.
We fill redundant gas pipelines with inert expanding foam, permanently rendering them safe and removing them from the active infrastructure register.
Fuel & Petrochemical Pipeline Filling
Disused fuel pipelines — particularly on forecourt sites, fuel depots, and distribution centres — need to be decommissioned correctly to avoid residual product pooling and future soil contamination risk.
We carry out foam and concrete filling of redundant fuel and petrochemical pipelines, with full documentation of the works.
Water & Sewerage Pipeline Decommissioning
Old water mains, sewerage infrastructure, and drainage pipelines are often left in the ground when routes are altered or infrastructure is upgraded.
Foam filling these redundant pipes prevents ground settlement, collapses, and the risk of future ingress — particularly relevant ahead of construction groundworks or where old utilities are identified during development.
RG22 Foam Filling vs Concrete Filling — What’s the Difference?
RG22 Foam Filling
- Specialist expanding foam for oil and fuel tank decommissioning.
- Absorbs residual hydrocarbons and flammable vapours.
- Makes the tank permanently inert and safe.
- Water-based, with no microplastics or PFAS.
- Does not produce heat during application or curing.
- Environmentally responsible option for in-situ tank abandonment.
- Uses compact equipment, keeping disruption to a minimum.
- Ideal for domestic properties, confined spaces, or sensitive locations.
- Reversible if needed — the foam can be removed and the tank recommissioned.
- Environmentally safe and designed to pose no pollution risk to the surrounding soil or groundwater.
- Extremely durable, with an expected lifespan of at least 150 years due to its very slow degradation rate.
- Reversible if future access is required; the foam can be removed, whereas concrete filling cannot realistically be reversed.
Concrete Filling
-
Concrete filling underground tanks is a permanent method of decommissioning tanks that cannot or do not need to be removed.
-
It is commonly used for older underground steel or plastic oil and fuel tanks.
- Once filled, the tank cannot be reused.
- Cost-effective where the tank will remain in place permanently.
- Suitable when no future access or recommissioning is required.
The best option depends on the tank type, size, location, and future plans for the site.
Our team will assess the tank and recommend the most suitable method.
What to Expect — Our Foam and Concrete Filling Process
- Prepare the tank before any filling work begins.
- Drain any remaining fuel or heating oil from the tank.
- Clean the inside of the tank to remove hydrocarbons, sludge, and flammable vapour.
- Confirm the tank is safe before filling. Filling an uncleaned tank is unsafe and not best practice.
- Fill the tank using either RG22 foam or concrete, depending on the agreed method.
- Make the tank fully inert, removing explosion and contamination risks.
- Provide completion documentation confirming the tank has been safely decommissioned.
- Use the documentation for insurance, conveyancing, or planning purposes.
