April 29, 20206 yr You haven't got much time between now and MBC starting work to get this sub base in, 240t is a hell of a lot of material, I remember having 21t delivered and that was a lot to move, admittedly I did it by hand.

June 29, 20206 yr In our case our foundation design showed 800mm sub-base below the 150mm MBC layer, but once we started digging the ground was perfect so we only went down 450mm and not 1250mm as had been suggested by MBC. Building inspector was more than happy and we saved on 180m3 muck-away and hardcore! BTW, MBC standard detail for foundations now seems to be type 2 + sharp sand rather than type 3 + fine gravel. I beleive this change is due to a change in the SE doing their foundation designs.
