Chalk mine subsidence has caused further damage in a Reading residential street. The hole appeared in a garden at lunchtime last Wednesday, close to the site of major subsidence in January. The previous hole (NCE 20 January) caused structural damage to the fronts of Victorian terrace houses at 6 and 8 Field Road. This time the 4m square 7.8m deep whole appeared in the back garden of number 18. It is not thought to have caused any structural damage. Plans by consultant Peter Brett and contractor Keller to stabilise the ground involve compaction and pressure grouting the known extent of the mine workings (NCE 14 September).
