This might have been understood or mentioned before in the forum but I could not find this basic information anywhere. How do we work out the slope of the block. As most builders say they cover for 300mm slope.
Our block is rectangularish. And engineering has 3 types of numbers for front two corners and 2 types of them at the rear. How does cut / fill affect this calculation? Any insight will be helpful.
- design surface level
existing surface level
top of batter level
Thanks
