We've built an extension using thermalite blockwork. It's been built for about a year now and we know (now!) that the blocks are prone to cracking.
On the ground floor there is quite a substantial crack and if you push the wall even about 2ft from the crack you can see a slight movement, only a couple of mm but just a bit concerned as it's holding the floor above.
Should I be worried about this and is there anything that can be done?
