I am getting bids for a new inground pool. Two builders place drain tile at base of pool and backfill with stone or sand. Another backfills with dirt, then about 6" from grade places drain tile. He says this is the only way to get a proper slope away from the pool to drainage easement. This builder uses the excavated dirt to backfill, which in my area is very heavy, sticky, clumpy clay. My concerns with each are: will backfilling with stone/sand encourage water to accumulate and will a proper slope be obtained with the base of the pool at 3' below grade? Will backfillling with this clumpy clay leave big pockets for water to sit?
Though my yard is bone dry in summer, I do get a LOT of water in the spring from snow melt so this is a great worry to me. Water behind the liner can cause it to float.
Which of these methods is the better?
Thanks.
