I'm planning to create a very small patio, about 1600 x 2600 (just to link my decking to the back gate) and I'm planning on using carpet stones. I have a concrete path running along the back of the house (between the decking and gate) about 900 wide then basically compacted rubble/mud which will all be covered by my new patio.

I've read up as much as possible about foundations etc but not sure on how strict I need to be considering it's such a small area and is only really going to be walked on every now and again. So a couple of questions if anyone can help:

Should I follow the standard guidelines on hardcore depth etc or can I get away with less hassle (work!)?
Can I leave the concrete path in place or should i dig it up (I have plenty of distance between the current path and the dampcourse)?
Should I still get a vibrating plate for compacting?

Any advice would be appreciated...

Cheers Murf.

If you have sufficient depth, lay the Carpet Stones on 25-30mm of 10:1 grit sand and cement on top of the existing concrete path and they'll be fine.

You need at least 150mm between the Carpet Stones (when they're laid) and the DPC

Thanks Tony, I'd kind of banked on that! A friend recommended making up slurry and applying that first to help it bond, I'll proceed on that basis. Certainly saved me some back-ache!
