Sorry to repost this, but I am desperate to sort it, as the footings are due to be poured first thing on Tuesday, so I will have to speak to the builder tomorrow if there are any alterations.
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. The floor level will be 210mm above the top of the trench at the high side. The floor spec is 100mm hardcore, DPM, 100mm steel reinforced slab, 75mm Celotex insulation, and 75mm (give or take) screed. say 350mm. The wall is to be brick and Celcon block, with a 50mm cavity.
Any help out there tonight?
Thanks
