Sand as Steel Wall Backfill

[DoDo1975]

Hi,

PB is recommending backfill of steel walled vinyl inground pool with sand. Most recommendations I have seen have been for 3/4 inch clean rock. There isn't alot of discussion I can find on using sand, except for fibreglass pools. Is sand a good choice? Why or why not? We are in an area with mild, but real winters.

Sand exhibits some liquid properties and can flow and wash out......not a good choice and am mildy surprised a PB would suggest it. 3/4 clean rock is the VERY best in my opinion. I back filled a 2' perimeter of a 25 x 54 pool and 12 years later, no settling whatsoever.......3/4" clean rock.
