Hi,
I have a patio which is approx 9 metres by 5 metres, but which had two brick planters built into it (either side of the centre). I have now removed the planters which has left me with two spaces that are exactly 2 slabs by 2 slabs, and I have a number of those slabs available. I therefore plan to fill the gaps with those slabs.
I am going to put in a 100mm MOT base and then 25mm of slab layer, but my concern is that I am adding new slabs in the middle of a long established patio and that I may need to account for settling.
The slabs are concrete 600x600x45.
I suspect that I can get the MOT tamped down sufficiently that settling won't be significant, but I am more concerned about compression of the slablayer (or perhaps even expansion when hydrated).
Just wondering if anybody has any pointers on minimising any problems.
Any thoughts would be much appreciated.
