The Brew Cabin

Hi
I have a brick wall contained area of 19.2 sq mtrs and 350mm high, on top of which, I want to lay a new slab patio. My question is please describe the materials and depths required to bring the level up to the top of the wall ready for the slabs.

Regards

All this information is already on the Patio Paving page - any make-up in levels is always done with sub-base material, either granular or CBM3.

Assuming you have a 50mm thick flag, then you need 50mm for the flag, 35-50mm for the bedding, and the rest is DTp1 or CBM3 compacted in layers of not more than 150mm depth.
