I know this has been probably beat to death, but I need to order my material tomorrow and need some quick suggestions. I am installing a new 18x48 Intex Ultra Frame on a small grade. I built a small retaining wall out of PT 6x6's, although it is not holding back much of a slope. I am building the grade up to level, not digging into the slope.
I will be adding another 6x6 at the bottom, I just left it out for now so I can get my tractor in there to fill the area. I was planning on getting some 2" gravel and compacting with a plate compactor. Then using sand for the last couple inches. There is around 8-9 inches to be added at the lowest spot. I have heard about class 5, but don't know what that is. What type of sand would I need, beech(dead), washed, etc????
Any help would be appreciated. Thanks.
