I currently have a concrete slab patio (600mm x 600mm x 2" slabs) covering an area of about 20ft x 30ft. I want to replace this patio with a more modern sandstone effect patio and wanted to know the views on over laying the slabs as there are so many slabs to would take ages to lift, then dispose of, where as overlaying would provide a solid level foundation.
could i over lay & what prep work would i need to do? also would i need to bed the new slabs down or could I simply rest them on the existing slabs with a bed of sand in between?
