3. how many kg of sand i need if my slope is about 6 cm and the gage is 3.05
thanks for the help
and agian sorry about my mistakes in my english
Sand will wash out most likely. Your frame will sink into the sand making it uneven again.
I would use some landscape timbers and build the low end up even (use a long board with a level taped to it to make you get ground even -- not good at explaining this hopefully someone else can help) with the high end.
That might let you use sand to level it out and pack it down then place paver blocks under your frame supports. Still not sure how good that would be as I am still learning on here myself.
