A hole in the road surface was initially reported to us on 12 May 2017 and it was quickly apparent then that this was not just a broken drain, but something more sizeable. Due to this, the road was immediately closed, and we arranged specialist investigations to tell us more about the issue.
A specialist survey company was employed to do the investigation on our behalf and we received the report from them in mid-August. Since receiving the reports we have been calculating the complex results of the survey with help from geotechnical experts and our engineers have been considering and interpreting the information in the reports so that we can decide on next steps.
The reports confirm that the void stretches six metres along the length of the road, and is around eight metres deep. It also highlighted that there was a small extension to the void on one side of the road and so we decided to undertake a second investigation to make sure that we were certain of the full extents of the void. This second investigation confirmed that there is nothing else causing us concern under the road in the area near the void.
We have been working closely with Dacorum Borough Council and the affected utilities companies to ensure that any work we carry out is properly coordinated.
Over the next few weeks will be some further investigation to ensure we know exactly the best way to fill the void. Once this has been determined we will be able to establish the timescales for filling the void.
We apologise for the inconvenience caused and would like to thank residents and road users for their patience.
