Crushed/Chipped Stone Backfill Material

Crushed/Chipped Stone Backfill Material

What is backfill material?

It is simply the  material  that we place  under the pool  and a round the outside of the pool shell after it is set in the excavated hole.

The use of  clean, crushed stone backfill  is imperative to the long-term success of a fiberglass pool installation.

Sand is the traditional material used in the industry, and it works well in areas with pure sandy soils. But it doesn’t take a soil specialist to understand what happens to sand when it becomes saturated with water: it  liquifies.

Consequently, we’ve experienced a much higher percentage of fiberglass pool installation issues when using sand as a backfill material: The pool shell  settles  after installation Leaks  develop from pressure on plumbing as a result of sand settlement The side walls of the pool shell  bulge

These are challenges we faced and fixed early on, but they virtually  went away overnight  the moment we stopped using sand and began using clean, crushed stone as our backfill material.

The plumbing is encased in stone as well, which  prevents plumbing settlement.

Unlike sand, the right stone backfill  will not move or settle. This creates a condition for long-term plumbing success.

It  drains better, it  doesn’t move, and  doesn’t change its properties when wet.
