Foam Filling Tanks


Safe Decommissioning In Situ

Foam filling tanks is a method of decommissioning a fuel or oil tank in its current position. When traditional tank cleaning and removal methods may not be feasible, foam filling provides a cost-effective and efficient alternative. This method ensures the tanks are rendered safe, saving both time and inconvenience. However, please note that foam filling may not be suitable when construction work is planned in the immediate vicinity of the tank.

The Benefits of Foam Filling Tanks

Foam filling tanks offers a range of advantages, making it a practical choice for various situations and industries:

Foam Filling Tanks - Our Process

The experienced in-house team at JWH Tanks oversees the entire foam filling process, ensuring safety and compliance throughout. Here’s how it works:

Initial Planning

After gathering essential information about your project, we design a safe system of work tailored to your specific requirements. Where required, we notify the petroleum licensing authority of the planned work.

Tank Preparation

We prepare the tanks for the foam filling process according to the APEA ‘Blue Book’, ensuring they are ready to receive the foam safely.

Accredited Foam Providers

Our accredited foam providers arrive on-site under our supervision and dispense the foam directly into the tank. The foam we use ensures that there are no voids left in the tank once it's filled, rendering it safely decommissioned.


Upon completion, you will receive a certificate confirming that the tanks are safe in situ, along with a hazardous waste consignment note for any waste removed from the site.

The choice between concrete and foam filling largely depends on cost considerations. Concrete typically has a far higher cost per cubic metre, but there are no additional fees for delivery. In contrast, foam has a lower cost per cubic metre, but there is a mobilisation cost.
Generally, larger tanks tend to be more cost-effective to foam fill due to the lower cost per cubic metre, while smaller tanks requiring only a few cubic metres may be more economical to concrete fill.

Before filling a tank, several preparatory steps are taken, especially if the tank previously contained petrol. The local licensing authority is informed, and a safe system of work is submitted for approval.
Once approved, our operatives prepare the tank by opening the necessary lids or flanges. The tank is then “bottomed,” which involves inserting a probe to the tank’s bottom to remove any remaining fuel below the suction lines. After bottoming and venting, the tank is ready to be filled, either by gravity-feeding concrete directly into the lid or dispensing foam through a flange.
Finally, a certificate of decommissioning is issued for each tank.

Tanks that have been solid-filled over the years are considered decommissioned. However, it’s essential to be cautious, as historical substandard filling materials can leave tanks potentially unsafe. Concrete or foam may settle unevenly, creating voids containing petrol vapours. These voids pose a risk, as incorrect equipment usage during tank opening can lead to explosions or harm.
We employ safe cold cutting methods to open and vent previously filled tanks, ensuring they are free from potential dangers. Once safely opened, any remaining product inside can be excavated and disposed of properly.

Foam filling is a versatile method suitable for various tank types, including fuel and oil tanks. However, its suitability may depend on specific site conditions and project requirements. Contact us to discuss your needs and determine if foam filling is the right choice for you.
