Hi,
Posting here because all of the online calculators seem to want me to have a height of 1 meter minimum - which is too high.
Can I just check Im not being thick.... Although anything is possible
I have a total height from the top of the footings to meet the top of the existing slab of 890mm
I have taken away 100mm for Celotex 155mm for the block and beam height leaving me 635mm for trench blocks (I might need to reduce the 100mm of Celotex to compensate for the screed over the block and beam plus the floor finish).
Trench blocks are 215mm in height which gives me just under 3 courses of block required. At a total "L" shaped length of 8.2 meters I will need 19 blocks a course * 3 = 60 Trencheroos in total?
Does this sound right?
Thanks and sorry for the stupid question
