Britteco provides professional foam filling services across the UK for redundant fuel tanks, underground voids, pipelines, shafts, chambers and other structures where a site assessment supports controlled filling instead of excavation or removal.
Using advanced RG22-grade industrial hardfoam — specified according to the application and current manufacturer technical data — Britteco delivers foam filling for tank decommissioning, void stabilisation, pipeline filling and confined space projects across commercial and industrial sites in the UK.
Foam filling (also referred to as foam injection) is a professional service used for filling redundant tanks, pipelines, underground voids, chambers, shafts, and structures where a site assessment supports leaving the structure in place.
At some point, tanks, pipelines, and underground structures reach the end of their operational life. In such cases, foam filling may offer a controlled filling option where removal is impractical, subject to environmental and structural assessment.
Britteco uses advanced RG22-grade water-based industrial hardfoam systems engineered for controlled expansion, uniform flow, and long-term structural stability in demanding underground and confined environments. The foam flows easily into complex spaces, filling voids completely without excessive pressure on surrounding structures.
The material is extremely lightweight — approximately 22 kg per cubic metre once cured — which makes it far lighter than traditional concrete or grout-based alternatives while still providing excellent stabilisation performance.
Where foam filling alone is not sufficient, full tank decommissioning and removal may be a suitable alternative. Britteco will assess the site and recommend the most appropriate and cost-effective solution for your specific situation.
Delivered across the UK for commercial and industrial projects requiring safe, controlled, and compliant foam filling, void filling, and tank stabilisation solutions.
Britteco manages the full foam filling process — from initial site assessment and preparation through to foam application, curing, and project sign-off.
We inspect the structure, access conditions, volume, geometry, and site risks before recommending the safest and most appropriate foam filling method — whether for a tank, pipeline, void, shaft, or chamber.
Site-specific Risk Assessment and Method Statement (RAMS) is produced before any works commence — covering all health and safety, environmental, and access risks for the project.
The structure is prepared for foam filling — including any residue removal, access point preparation, and venting arrangements required to ensure controlled and uniform foam flow.
RG22-grade industrial hardfoam is applied on site, flowing into complex spaces and expanding in a controlled manner to fill the void completely without creating excessive pressure on the surrounding structure.
The foam is left to cure in place. Once cured, the fill is inspected to confirm coverage and performance before the site is handed back.
Suitable project documentation is provided on completion — supporting compliance, planning, redevelopment, and handover requirements for the site.
Every foam filling project is planned and delivered with a strong focus on health and safety, environmental responsibility, and industry best practice — protecting our team, our clients, and the environment on every site.
All works are planned and executed in accordance with current health and safety legislation. Site-specific risk assessments and method statements are produced for every project before work commences.
Site-specific Risk Assessment and Method Statement documentation is prepared as standard for all commercial, industrial, and confined-space foam filling projects — ensuring every job is properly planned before works begin.
Suitability depends on the specified material, ground conditions, contamination assessment and intended future use. Filling does not treat existing soil or groundwater contamination and does not automatically make a tank environmentally safe. Product documentation and any environmental requirements must be checked before installation. Site waste and residues are handled through appropriate waste routes.
On completion of every foam filling project, Britteco provides suitable project documentation — supporting compliance, planning, insurance, audit, and redevelopment requirements.

Foam filling requires controlled application, proper site assessment, and the right material for long-term performance. Britteco provides a professional foam filling service across the UK — covering tank decommissioning, void filling, pipeline filling, shaft and chamber filling, and ground stabilisation for commercial and industrial projects.
In many cases, there is no need for full tank or pipeline removal, reducing disruption to your site and surrounding assets — ideal for congested or restricted access locations.
Fast application allows projects to be completed more quickly than many traditional filling or excavation methods — reducing programme time and associated costs.
At approximately 22 kg/m³ once cured, the foam places minimal load on surrounding structures compared with concrete or grout-based alternatives.
The foam expands in a controlled manner and flows into complex spaces without creating unnecessary pressure on the structure — even in confined and hard-to-access environments.
Fire performance depends on the specified product and its tested classification. Confirm the current manufacturer technical and safety data for the proposed application. Tank-filling foam is not firefighting foam or a fire barrier, and does not replace fuel removal, cleaning, vapour controls or a site-specific risk assessment.
Expected service life depends on the product specification, installation and site conditions. Britteco assesses these for each project; a universal 150-year performance guarantee should not be assumed.
Britteco uses advanced RG22-grade industrial hardfoam systems designed for underground void filling, pipeline decommissioning, tank filling, and long-term structural stabilisation.
Technical data shown for indicative guidance. Performance may vary depending on site conditions, structure geometry, moisture, and application method.
Where a tank requires full removal, cleaning, certification or fuel uplift prior to decommissioning, Britteco provides a complete range of associated tank services — including tank decommissioning, tank removal and waste fuel disposal.
Common questions about foam filling, tank decommissioning, pipeline filling, void stabilisation, and the technical performance of the materials used.
Foam filling is used to safely fill and stabilise redundant tanks, pipelines, underground voids, cavities, shafts, chambers, ducts, and other disused structures where excavation is not practical or where a fast, controlled filling solution is required.
Void filling is the process of filling underground spaces, cavities, redundant chambers, shafts, or voids with a lightweight controlled material to reduce collapse risk, improve stability, and support long-term ground safety.
Foam filling may be appropriate after a tank has been properly decommissioned and the site assessed. It is not a substitute for removing fuel and residues or controlling vapours. Where removal is impractical, the filling material and any structural or environmental requirements must be specified for the project.
Britteco uses advanced RG22-grade water-based industrial hardfoam systems designed for long-term underground filling and stabilisation. Once cured, the foam has an apparent density of approximately 22 kg per cubic metre and is engineered for controlled expansion, structural stability, and low load on surrounding structures.
Fire performance depends on the specified product and its tested classification. Confirm the current manufacturer technical and safety data for the proposed application. Tank-filling foam is not firefighting foam or a fire barrier, and does not replace fuel removal, cleaning, vapour controls or a site-specific risk assessment.
Suitability depends on the specified material, ground conditions, contamination assessment and intended future use. Filling does not treat existing soil or groundwater contamination and does not automatically make a tank environmentally safe. Product documentation and any environmental requirements must be checked before installation.
Foam filling is significantly lighter, faster to install, and creates less pressure on surrounding structures compared with concrete or grout-based methods. It is particularly useful in confined spaces, underground assets, and projects where excavation needs to be minimised or avoided entirely.
Expected service life depends on the product specification, installation and site conditions. Britteco assesses these for each project; a universal 150-year performance guarantee should not be assumed.
Yes. Although the foam provides a durable, permanent-quality fill, it can be mechanically removed if required by cutting, breaking, or digging out the cured material. This makes it a practical solution for sites that may require future access or redevelopment.
In many cases, yes. Foam filling can reduce or eliminate the need for major excavation, helping lower disruption, shorten project timescales, and reduce overall site costs.
Foam filling can be used for fuel tanks, underground tanks, pipelines, pipework, chambers, shafts, ducts, cavities, voids, confined spaces, and selected industrial structures requiring safe, controlled, and lightweight stabilisation.
Yes. Foam filling is widely used to decommission petrol, diesel, and heating oil tanks in situ — filling the tank in place to render it inert and safe without excavation or removal. Where full tank removal, fuel uplift, cleaning, and certification is required, Britteco also provides a complete fuel and oil tank decommissioning service.
In most cases, remaining fuel and residues should be removed before foam filling commences. Unlike concrete filling, foam filling does not always require full degassing before the foam is injected — the RG22 hardfoam absorbs residual hydrocarbons, helping to render the tank inert and safe. For tanks that require full cleaning, gas-freeing, removal, and certification, see our fuel and oil tank decommissioning service.
Yes. On completion of every foam filling project, Britteco provides suitable project documentation to support compliance, planning, insurance, and audit requirements. For projects requiring a full certificate of disposal, see our fuel and oil tank decommissioning service.
