We were contacted by a company about an underground oil tank which had been out of use for a long time. Underground tanks like these require special tools and always a risk assessment before doing the job.
The tank was sitting underground for about 30 years and needed to be filled up with concrete to make the area above safe.
Before any concrete goes into the tank it has to be decommissioned and made sure that there is no oil left in it. To get the oil and sludge out of the tank we use pumps and vacuums along with specialist tools.
After decommissioning the tank it’s then filled up with concrete.
When we are filling up the underground tanks we use special tools to make sure that there are no air pockets in the tank and it’s filled up to the top.
If your oil tank is installed in an easy-to-access location, we can often remove it in one piece via excavation and crane removal. If your oil tank is installed in a difficult to access location, or if you’ve subsequently built on top of the oil tank, our team may need to remove the oil tank in pieces.
For safety, we’ll cut your tank using Cold Cutting and spark-free tools.
