Commence picture dump..
2 old foundations and a huge lump of concrete where an old doorway used to be, must have been used for elephants or something.. And also the old concrete apron infront of the door..
Tried my best to remove it with a sledge hammer and steel pins but 20 minutes of hammering resulted in a little tiny piece that broke off.. so gave up
Meanwhile material arrived... 3x 150mm ytong + 1x ytong floor blocks and 4 beams ontop
Next day approx 9 tonne aggregate for concrete arrived..
after those holes were filled and approx 20cm was above it I placed reinforcement in there as well to tie it all together to stop it cracking hopefully!
These panels were also reinforced, and had to have the metal removed..
