What happened to backfilling with stone at the same rate as the water is filling the pool within 12"-18" of each other so that the walls don't bow in or out?
According to Latham: First, 6” of sand or 6” of ½” gravel is placed around the bottom radius of the pool. The pool is then filled with 6” of water. To ensure that pressure on the outer and inner walls of the pool remains equal throughout backfilling, your builder will alternate between locking in the pool with six inches of gravel, then filling the pool with six inches of water. Working with care and precision, your builder will continue to alternate between these procedures until backfilling and pool filling is complete.
