My electrician knocked one of the internal blocks loose whilst drilling through at ceiling joist level. In attempting to remove the mortar from the block below in readiness to re-affix it, I loosened that block as well. It seems that the mortar is harder than the surface of the block. I now have three blocks needing to be re-seated.
I need to re-seat the blocks without removing the mortar. Any suggestions? Dare I say it, could I use expanding foam etc?
I suppose the proper solution would be to add a mortar bed on top of the existing bed and then at the top, trim the block/s back to fit under the joist?
