We are landscaping our garden and part of this is replacing the old grey 3 x 2 slabs with new riven slabs.
Two of the slabs appear to have been laid under the external cladding of the house (directly underneath a set of double patio doors).
When trying to lift up the slabs (first picture) with a shovel wedged under the side furthest away from the house, the slight levering of the slab was disturbing the buff/sandstone external cladding directly underneath the door.
It appears about c. 9-11cm of the slab was actually wedged underneath the cladding.
Having cut the slab away with a stihl saw, and then using a bolster/hammer to finish/dress the visible edge of the slab, we've been left with the situation where the part of the slab that is still under the external cladding has actually had its mortared bond with the cladding broken and is leaving a gap of c. 3-5mm (height) and 80-100mm (depth, tested by sticking a sharp trowel in the gap and seeing how far back it can go). See final 5 pics.
Two questions:-
1. Does this affect the structure of the house in any way?
2. What should we do to rectify this?
The house is a traditional build with double skin breezeblock. The slabs that were causing the problem were (only) directly underneath the patio doors.
