Hi,

My existing driveway is old concrete which is looking tired, with weeds sprouting through etc etc.

I understand there is a sub base required normally, such as hardcore then sand. Could i just put a layer of sand over existing concrete driveway then cover with weed membrane then put my slate on?

I dont want to dig up my driveway and contractors are to expensive, I know it may not be ideal but is it ok?

Many Thanks
John
