Decommissioning

Foam filling UK services are 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 UK 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.

Yes. Foam filling can form one part of a tank decommissioning programme, particularly where a tank or structure is to be filled in place rather than removed. It helps render the structure inert and reduces risks associated with vapour and long-term instability. Where full tank removal is required, Britteco also provides a separate tank decommissioning and removal service.

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.

The cured foam is classified as non-flammable and does not support combustion under normal conditions. Softening begins at elevated temperatures, flash ignition occurs only at around 235 °C, and self-ignition at approximately 620 °C. While it is not marketed as a fire barrier, it helps reduce risks associated with residual fuels and vapours in decommissioned structures.

The foam system is water-based and environmentally considerate, with biodegradable characteristics and no known ecotoxic effects once cured. In suitable applications, the cured material may also be incorporated into ground improvement works where appropriate.

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.

The foam is designed for long-term underground stability in suitable dry conditions. It offers minimal shrinkage, strong resistance to hydrocarbons and mineral oils, and a design life of at least 150 years in suitable dry underground conditions.

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 practical 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.
