Yes, you can put sand under an above ground pool, and it's often the recommended base! However, the type of sand matters.
Using Sand as a Base for Your Above Ground Pool
Sand provides a smooth, level surface to protect the pool liner and ensure a comfortable swimming experience. It helps prevent rocks or roots from damaging the liner over time.
Choosing the Right Type of Sand
While sand is a great option, not all sand is suitable. Avoid using just any sand you find.
-
Play Sand: This is generally the worst choice. It's often too fine and can easily wash away or compact unevenly.
-
Moulding Sand (Foundry Sand): This type binds together more closely when moisture is added. While it might seem ideal, it can become too hard and unyielding over time, potentially causing problems if the ground shifts slightly.
-
Concrete Sand (Coarse Sand): Concrete sand is a good choice. It's clean, relatively inexpensive, and compacts well without becoming too hard. It allows for some drainage.
-
Masonry Sand: Another option, however check the specific type, as some masonry sand may be too fine.
Why Sand is a Good Choice
- Leveling: Sand is excellent for creating a perfectly level surface.
- Protection: It cushions the pool liner from rocks and debris.
- Comfort: It provides a softer surface to walk on around the pool's edge.
Installation Tips
-
Prepare the Ground: Remove all grass, rocks, and debris from the area where the pool will be located.
-
Level the Ground: Use a level and shovel to create a perfectly level surface. This is crucial for the stability of the pool.
-
Add the Sand: Spread a layer of sand (typically 2-3 inches thick) evenly over the leveled area.
-
Compact the Sand: Use a hand tamper or roller to compact the sand, creating a firm and stable base.
-
Check for Level Again: Double-check that the surface is still level after compacting.
-
Protect the Sand: Consider using a geotextile fabric (weed barrier) underneath the sand layer to prevent weeds from growing through and to help stabilize the sand.
By using the right type of sand and following proper installation techniques, you can create a solid and reliable base for your above ground pool.
