Hi guys. Can you help me out with this one?

I would normally lay my sandstone on a mortar bed but a customer wants the patio joints & base to be completely permeable & also wants to be able to plant very small plants in the joints. Is it possible & how would I go about this? The sandstone she has isn't calibrated incidently.

Many thanks, James

use pieces of timber in the joints to hold the bed in place under each flag but stop it falling away into the jointing area, when the bed has set remove the timbers and use soil for the roots of the planting and top off with decorative gravel

the flags would have to be on a 100mm minimum sub base for drainage, use a clean stone instead of MOT type 1

Great! Thanks Mick.

So in theory then as the joints are permeable I can lay the patio dead level without my usual fall??

Cheers
