Should I use vermiculite or sand in an Above ground pool base base?

The best material to use for an above ground pool base is crushed stone.

Crushed stone is a great option because it is:

- Leveling: Crushed stone can be easily leveled to create a smooth and even surface for the pool.

- Drainage: It allows for proper drainage, preventing water from pooling and causing damage to the pool.

- Compacting: Crushed stone can be compacted to provide a stable and solid base for the pool.

Vermiculite and sand are not recommended as they can be more difficult to level and compact, and they may not provide adequate drainage.
