I posted in Nov. '07 about limestone paving thickness. The patio was duly laid in 2008, following all the advice on this site. The 20 mm stone was sealed with Lithofin.
Now, after some sustained frost, i.e. a normal English winter, many of the slabs have cracked and broken open quite spectacularly.
None of the other stone used around the house has cracked. There is even a 20 mm limestone which was left over from use inside the house; this came from a different supplier.
I bought this limestone on condition it was suitable for external use but I seem to have been sold a lemon.
I'm probably off next week to Surrey trading standards where the supplier is based and later my county court but I'd appreciate any comments.
Meanwhile thanks for this excellent site. Your design for a linear rainwater soakaway in well-drained soil works well and was easy to install.
