Block paving

[ragj195]

Hi

I want to block pave the drive but lay blue slate in the area in front of the windows which a car will also park on. There will be a transition from blocks to slate. What is the best way to make sure this border doesn't collapse over time? Should in lay pin kerbs in concrete as a border to the blocks or will haunching border blocks be okay?

Thx

Lay the border on a concrete brace (strip). Haunching wont hep on it's own.

If your slate is the right sort (thickness) for paving it needs bedding down onto hardcore with a full mortar bed. It will be as secure as the block paving.

My own block paving abuts flags without any need to restrain the paving no problem in 20 years still. My flags are bedded on a full bed of weak sand/cement old 3' x 2's
