Lay and Roughly Level the Gravel Sub-Base

What happens here

While the video already shows workers with a layer of gravel, this step in a DIY sequence would involve introducing and roughly leveling the initial layer of crushed stone or gravel into the excavated pit. This material provides a stable, free-draining foundation. The material should be spread relatively evenly, aiming for a base thickness specified by the pool manufacturer or local building codes, typically 4-6 inches. Use shovels to distribute the gravel and rakes to spread it out.

Goal: Establish a primary layer of gravel for drainage and initial support.
