Hello.
Our house was built in 1966 and the kitchen was extended in 1973, the new floor was laid with Platt quarry tiles. Until last month we had no problems. Then I noticed a 10ft long hairline crack along the line of the join between the old and new solid floors. Two surveyors have said that it's not subsidence, but a result of the house being built on clay, poor consolidation of the extension infill, and the recent drought.
To me this is a really serious problem and I don't know where to look for a solution: I can find tile restoration companies online but they seem to deal with Victorian and church tiles. Companies providing expansion joints seem to deal with commercial jobs. I would appreciate any professional advice.
