1. What is Pool Sand Base Calculation?

The sand base calculation determines how much sand is needed to create a proper foundation for an above-ground pool. A typical depth of 5 cm (0.05 m) is recommended for most installations.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Sand (kg)} = \text{Area (m²)} \times \text{Depth (m)} \times \text{Density (kg/m³)} \]

Where:

\( Area \) — The area covered by your pool (π × radius² for round pools)
\( Depth \) — Recommended depth is 0.05 meters (5 cm)
\( Density \) — Standard sand density is 1600 kg/m³

Explanation: The calculation multiplies the volume (area × depth) by the density to get the weight of sand required.

3. Importance of Proper Sand Base

Details: A proper sand base provides a smooth surface, protects the pool liner from punctures, helps with leveling, and provides cushioning for the pool floor.

4. Using the Calculator

Tips: Measure your pool's area accurately. For round pools, use π × radius² (radius = diameter/2). The standard depth is 0.05 m unless specified otherwise by your pool manufacturer.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate area for a round pool?
A: Area = π × radius² (π ≈ 3.1416, radius = diameter/2). For a 4.5m diameter pool: 3.1416 × (2.25)² ≈ 15.9 m².

Q2: Can I use less than 5cm depth?
A: Not recommended. Less sand may lead to an uneven base and potential liner damage.

Q3: What type of sand should I use?
A: Use masonry or concrete sand (not play sand). It should be clean, sharp, and free of debris.

Q4: How many bags of sand will I need?
A: Divide the total kg by bag size (typically 25kg bags). Example: 1275 kg ÷ 25 kg/bag = 51 bags.

Q5: Should I compact the sand?
A: Lightly level but don't over-compact. The sand should remain slightly loose for comfort underfoot.
