I have got a solid concrete drive and want to lay block paving. Do I have to dig it all out to 10" to refil with hard core and then wack a plate it or can I just lay sand on the concrete and lay the block paving on top of this? Also to consider, where the driveway meets the street, is it level at the moment? If it is and you lay block paving on top of your current driveway, where it meets the street, there will be a slight bump depending on how thick the block you’re using. You could just dig up the concrete driveway 2′ away from the street and have a slight slope to circumvent this problem though, but aesthetically, it won’t be as nice.

yes you can lay your paving on top.make sure there are drainage holes where needed and put sand and block on top.

Yes if the drive was laid correctly, depends on the base of existing drive and as above you will need drains for sure.

the concrete should be fine if it is well laid. if you’ve been driving over it for years then it should be ok. the worry will be the drainage. if it’s fairly flat you will need to cut/drill holes for drainage and this isn’t easy. better to hire a really good drill and bits from hire shop. the blocks are strong but prone to damage if wet and very cold.

Is there a garage Jayne? what about a curb onto the street? Those would need to be level.

Draingae depends on whether your driveway has a slope or not, and if so, which way is it sloping. Alternatively, you could make the new block paving slope from the middle outwards towards the 2 sides, which will also take care of drainage (assuming you’ve got grass on both sides of the driveway). Also to consider, where the driveway meets the street, is it level at the moment?
