Basically the current plan is to dig down to a depth of 215cm with a length of 4.5m and width of 3m
I plan to lay concrete forms and place slab foundation around the perimeter of the hole, (20 inches wide and with a bed of 6 inches of gravel underneath a slab of 6 inches concrete) directly under where i will be building the walls using 440 x 215 x 215 hollow concrete blocks. My question is, when i backfill the hole and re bury the room, will the structure hold the weight of the earth? If it would not could someone please give me advise on how best to make it work, also please dont try and talk me out of it, i have taken safetey into account and im willing to take the risk, like with any building project.
Ok to sum up, here i go, basically the building will be made by 8x8x16 inch hollow blocks, reinforced with rebar every other cell, the ceiling will be made from 2 inch thick c16 timber, and treated and felted, there will only be 6-8 inches of soil on top of the building so no problem with supporting the weight from above, i shall be installing a french drain around the perimeter of the foundations, and backfilling with 40mm limestone, oh and the soil is quite heavy clay based, hope that helps, so do you think this should stand the test of time and the tensions from the soil.,
