Hello,
Suddenly found a crack in the free standing garage wall and need some advise on how much of a problem it may be, though a bit of a tale on its construction.
The main garage was self built 40 years ago, with full depth foundations to the inspectors requirements etc.
As there was some waste space at the back of the garage, we removed to loose top soil and put a layer of hardcore down so any excess concrete from the laying of the main base could be used to make a storage area, it ended up about 4" thick of concrete.
Some 30 years ago we wanted a bit more space in the garage for a little workshop so we knocked a doorway though the rear wall and added the 3 foot extension with the same blocks onto this rear slab.
( though yes, we should have done proper footings !)
Its all been fine for all these years, but last week be suddenly noticed a line of cracks in the blockwork joints on one side as the red line shows.
Also the extensions dpc looks like theres a movement crack all around it.
We can just get a 1mm spacer in the top area of the cracks and in where the dpc is.
There have been no changes to the surrounding land /properties, so wonder if this is just a small 'settlement' crack we can live with or possibly something more serious ?
We are on the hills in the north of England, but not an area known for subsidence.
