Redundant boreholes must be decommissioned to a high standard to ensure the site remains safe and mitigate the risk of groundwater pollution, gas release or oxygen ingress, which can cause fires. Dragon Drilling specialises in the decommissioning of both disused gas and leachate wells and boreholes.
As Chartered Environmental Engineers, we can ensure the decommissioning of a particular site is carried out according to regulations stipulated by the Environment Agency. As each site differs in terms of usage, geology and borehole construction, our expertise ensures projects are completed efficiently and successfully.
Once we have identified the exact requirements of a particular site, we operate our patented bentonite mixer to swiftly complete the work. The mixed bentonite slurry ensures an effective back fill from top to bottom. All steel casing required for decommissioning sites is fabricated at our in-house manufacturing facility.
