I have an old concrete base with shed on top and it is all crumbling.
Plan is to remove crumbling concrete and lay pavers over the top
some areas are a lot higher and there is a height difference of about 3 inches from shed entrance to edge of concrete

will I have to remove all concrete to a level base or can I build up using sand /cement mix

is the best way using a grinder or chipping away with sledge hammer

what depth of sand /cement for pavers

Hi

Not sure if you can get away with laying over top, will leave that reply to others, but if you do need to remove concrete get a sds rotary hammer drill. I used mine they will brake up concrete easy. Can be got from argos for around £50.

Good luck
