Not sure how to handle this and its the first thing I need to decide on before doing anything else! I have recently acquired a 1960 Derby based house from my parents and understand that is has an issue with sulphate based hardcore / ground floor.
Underfoot the floor feels obviously un-even with some ridges and bulges, (it has been like this for the last 20 years with very little change according to my parents) I've not seen the actual concrete as there are still floor tiles down. There doesn't appear to be any problems with the walls. No cracking or bulging etc.
I've knocked on a few neighbours doors, they all seem aware of the problem and some have had it replaced. Any replacements were done in the 1980s, no one seems to have had it done more recently..
The information online is fairly confusing, some people recommending core samples and others saying that they are a waste of time.
I guess my options are to have the floor dug out and replaced or leave it, level it off the best I can and hope there is no further reaction or it doesn't move.
Anyone have any advice or dealt with this before?
