I am fairly new to site and definitely new to pool ownership so I have been scouring site for months and have found that there is a wealth of knowledge represented; therefore, I come humbly seeking advice.
We are in process of building Versa-lock wall which will be abt 10' at tallest point and 130 ft long with avg depth of 6'. We have had it engineered and will, of course, be using geogrid for reinforcement. Bacically we are creating back yard which pool can be built. PB would like compacted crusher run under pool but we do have to back fill the 8' or so from wall with something. Engineer recommended #57 stone which takes very little compaction but does cost more per ton than crusher run. Crusher run is less but what I don't know is what all is involved in compacting. Obviously it will increase cost but not sure if I would be just as well off to use the 57's.
I appreciate any thoughts or opinions. At this point, I feel we are building the Great Wall of China! DH has put me in charge of contracting which I am not a novice; however, in the arena of pools and retaining walls....So much to learn.
I will post photos of progress but change topic to "have we lost our minds!"
