Can you put a new patio over an old one?

We have an old patio laid which is even but some of the slabs have crumbled a little with the frost and ice. As we need to make it a bit higher as well would we be able to do this? Any ideas please, I would be very grateful.

Mot recommended especially if existing are wobbly as this will transfer through the layers and make the new slabs as bad and crack them too.

The secret of good slab laying is getting a decent base first.

Cover it up with decking if its only small area, that way you gain your height and you cover it up at the same time.

The base is fine and the slabs as such none are wobbly at all. Just some are crumbling in the middle, but I presume that they can be filled with sand.

We have paving slabs down for our shed....it was letting water in so we dismantled it, put another layer of paving slabs down over the top and put shed back on....no problem at all

Thank you for all replies

you'd have to dig the original one up to get the in-laws under it then put the second one over it !
