Hi folks,
Im doing a totally DIY freeform steel wall pool with an 8 foot deep end, 9radius sloping to 5 foot radius at the bottom. On the deep end, i had to remove several very large sand stone rocks from my heavy clay soil that were simply too thick to break. Most of the wall looks pretty good and shelf integrity is good. But where i pulled out the big rocks (20 x30 inch) sized rocks there are sunken in cavities where the rocks once rested.
My question is how to bring those cavities back up to wall? Is it ok to Use existing clay soil, wet it a bit and tamp it in? Or maybe tamped 2RC or washed 2B? Concrete maybe? or is it ok to go heavy on the pool base?
Any help is appreciated and thank you!
