Achieve Precise Base Leveling for Fiberglass Pool

What happens here
This is the most crucial step, extensively shown in the video. Workers are seen meticulously raking and smoothing the gravel layer to achieve a perfectly flat and level surface. Given that the pool is fiberglass with a flat bottom, the narrator stresses that *every single point* of the base must make perfect contact with the pool shell. This prevents air gaps, which could lead to stress points, cracking, or settlement issues over time. Use a long, straight screed board (like a 2x4) and a spirit level or laser level to check for high and low spots. Add or remove gravel as needed, raking smoothly to maintain consistency. This process is iterative and requires patience and precision.
Goal: Create a perfectly flat and level foundation to support the entire flat bottom of the fiberglass pool.
Tools and materials
- Long Straight Edge — A long, straight piece of lumber (e.g., a 2x4 or aluminum screed) used to scrape and level the gravel
- Rakes — For fine-tuning the distribution of gravel and smoothing the surface
- Shovel/Trowel — For adding or removing small amounts of gravel for fine adjustments
- Spirit Level — To check the levelness across the straight edge and the entire base
- String Line and Stakes — To establish reference points and guide the desired finished grade
- Additional Crushed Stone/Gravel N/A — To fill any low spots identified during the precise leveling process
