Sandstone lift and Relay

The customer was having problems with their sandstone patio. An investigation revealed a collapse in the sub base. The ground was not compacted and the the ‘5 dab’ technique reared its head. There was no run on the patio, resulting in the rainwater following into the middle of the surface. The task was to lift, clean and reuse the existing stone. Remove the earth , lay and compact type 1 and then lay the sandstone on a bed of mortar.
