Hundreds of residents thought to be living on top of crumbling chalk mines are to hear what progress has been made in protecting their homes.
Engineers have been probing roads in the Coley area
A mine was discovered under the back garden of a house in Castle Street, Reading, Berkshire, in July - five years after a cave-in happened nearby.
Residents will hear the results of tests in the Field Road and Coley areas of the town at a public meeting.
About 30 homes had to be evacuated after the first cave-in at Field Road.
The £2.6m scheme to check the area for the Victorian mines, which was started in May, is due to finish at the end of the year.
Councillor Catherine Wilton said: "Now that we are past the halfway mark we thought it was a good time to invite people along to a meeting to give an update on how the project is running.
"Of course, we won't know the full results of the investigation works until next year and we will make direct contact with any householders whose properties may need urgent action following the discovery of any chalk mine workings."
The meeting takes place at the civic offices on Thursday.
