We recently had a call out to a split single skinned plastic tank spraying oil on a drive. Although, we managed to stop oil running out onto the highway, the oil had already ruined the drive and ground around it.
It will cost around £50k to rectify all the damage.
Unfortunately, this accident will need mentioning to any potential home buyers due to the long term effects that could have been incurred on water course etc. This could obviously cause further financial loss.
