I had a sandstone patio laid in an incredibly bad way and had to pay for the privilege. Slabs butted up and slabs lifting / rocking.
I am easily able to remove the slabs, it seems like the mortar itself is solid bar a few hollows, it just hasn't taken to the slabs due to them not being wetted during the extreme heat.
I noticed a slurry mix can be used to relay a rocking slab, but can i use it to lay the whole thing again? Reason I am asking is I can't go any higher with the mortar or I'm above dpc - only other option is to dig it all up.
