What we are doing
We wrote to you in September about works to decommission a borehole outside no. 183 Gloucester Avenue from 13 to 14 October 2025. The works were not completed due to safety stand down to SCS works.
These works will now take place from Wednesday 19 November and Thursday 20 November 2025. We will let you know if there are any further changes.
A borehole is a narrow, deep hole drilled into the ground to access subsurface for information on underground conditions. The borehole is within parking bays outside no.183.
We will put barriers around the borehole, unblock it if necessary, refill it with grout and then tarmac over it. This will take up to three hours, but the barriers will stay in place until the grout and tarmac are dry.
This work may be noisy. We will use noise reducing barriers where possible.
We will need to suspend up to two parking bays. Vehicles carrying the grouting materials and grout pump will be parked within our works area.
