Underground Tank Decommissioning

Underground fuel storage tanks can be decommission by several methods, traditionally, this was achieved by cleaning the tank to a gas free state, then poring concrete in to the underground tank for a permanent solution. Water filling is often used a temporary method, but this can cause problems with accelerated corrosion and any remaining hydrocarbons forming an environmentally hazardous sludge that will require expensive treatment to make safe.   An alternative is to inject a foam resin in to the tank, which has may advantages.

Foam Filling underground tanks.

Decommissioning underground fuel storage tanks with RG22 resin foam is the most cost effective and environmentally preferred method with the following advantages:Tank decommission foam filled

  • The redundant tank will not require a full clean and de-gas, just pump out any remain fuel. The foam is ejected directly through the tank lid.
  • Concrete can leave hollow voids, especially in larger tanks.
  • The foam will absorb and make safe any remaining hydrocarbons.
  • The RG22 Foam has a mass of 25kg per 1000L allowing for complete tank removal at a later date, if required.
  • The process is fast, preparing pipework and injecting the tank is simple - allowing for several tanks to be decommissioned in a day.
  • The foam is non toxic and will protect the tank walls from corrosion.
  • If the tanks in good condition and required for future use - The foam can be removed.
