The amount of hardcore depends how good Ive been with the digger, Usually we make the whole site up to just below the required level then dig out the trench for the panel base, aim for around 300mm past the panel each sideHow much hardcore do you have under the 100mm of concrete @Fraserb ? And how far do you extend it past the edge of the panel?
