Now that gravel has become the accepted standard (over sand) as the backfill and base material used in the fiberglass pool industry, many persons often inquire with our company as to the type of gravel/stone that should be used as well as the amount typically required when installing a fiberglass pool.
Although this information is fully explained in the video, here are a couple of bullet points to make a note of:
The type of gravel used is #68 stone (clean, no fine dust)
Most installs will use 40–60 tons of gravel
Never mix your gravel with other materials, especially dirt
