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.
When the job is finished we make sure that we leave the site clean and tidy and we provide each customer with the right certificates.
