I have been asked by someone to lay a patio. The area is on an old area of lawn and flower bed 11 slabs by 4 (60mm by 60mm slabs ) I was planning to put down 75mm of type one sub base compacted as best as i can and laying the slabs on a 50mm of sharp sand /cement (10:1) full bed and pointing up afterwards. my question is, is this depth of sub base over the top? I dont want to have to barrow tonnes of sub soil and tonnes of sub base. Any advice would be appreciated.
