Raised Patio Sub base
Posted: Tue Jan 25, 2011 1:32 pm
We have had a retaining wall built to form the boundard of a raised patio. We have backfilled the area with some large rubble from the wall that formed the edge of the old patio and now need to add some finer material on top to form a good base before laying the sharp sand to form the bed. The question is do we use 20mm crusher run or 40mm crusher Run or MoT1.
