I've just removed the tiles from a section of bathroom wall and noticed the plaster behind them is cracked along all the mortar lines and through the centre of the supporting Thermolite blocks behind.
When I removed a large area of loose plaster/sand&cement render I could see the cracks had gone right through the mortar lines and the centre of the blocks. The wall does not sound nice and solid but rather loose when banged with my fist.
The problem area is in a 2 to 4.5 metre central section of the inner leaf of an external wall. The wall either side of this area, which is painted with emulsion, does not appear to be affected just the central section which was/is tiled.
Is this cracking a problem that requires fixing before I re-plaster and re-tile?
If it is , whats the best way to put it right?
I've seen expanded metal strip nailed in place over odd wall cracks then plastered over but I think my problem is too extensive for this approach.
Any ideas would be much appreciated.
