Yes it's me again.
Conservatory footings have now been dug to support a dwarf wall 450mm high. Footings have been dug to 580mm deep and 400mm wide all round. There is 450 mm difference in height from top to bottom of slope, over the 6.2 m length of structure.
Is this depth and width OK? (my plan spec reads 1000mm x 450mm) The difference in height will clearly affect the footings depth, as, by my calculation, given level foundations, the depth of concrete on the high end of the building will only be 130mm, unless the footings are stepped up, which I hope is the plan.
Any comments gratefully received.
