ok i am having a huge think here, snakes and moisture, but, and like me its a big butt
, can i get away with a fully integrated slab which would be 800mm thick in the middle for 1.8m2 and then the overall thickness would be 200mm on the outer edges for a total size of 3x3m. the 2.3m dome would sit on this and the pier mounted in the middle? would this be stable enough?
