Can I lay block paving on top of my concrete driveway?

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? 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.  more
