1. What is the Sand Calculator For Round Pool?

This calculator determines the amount of sand needed to create a level base for a round swimming pool. It calculates based on the pool's radius, desired sand depth, and sand density.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \pi \) — Mathematical constant (approximately 3.14159)
• \( \text{Radius} \) — Radius of the pool in meters
• \( \text{Depth} \) — Depth of sand layer in meters (typically 0.05m or 5cm)
• \( \text{Density} \) — Density of sand (typically 1600 kg/m³)

Explanation: The formula calculates the volume of a cylinder (πr²h) and multiplies by density to get mass.

3. Importance of Accurate Sand Calculation

Details: Proper sand base is crucial for pool stability and leveling. Too little sand can lead to uneven settling, while too much is wasteful and expensive.

4. Using the Calculator

Tips: Measure pool radius carefully in meters. Standard sand depth is 5cm (0.05m). Sand density typically ranges from 1500-1700 kg/m³ (default is 1600).

5. Frequently Asked Questions (FAQ)

Q1: Why is sand used under pools?
A: Sand provides a smooth, level surface that protects the pool liner from punctures and helps distribute weight evenly.

Q2: What if my pool isn't perfectly round?
A: For oval pools, calculate as if it were round using the longest radius, then add 10-15% extra sand.

Q3: Can I use this for rectangular pools?
A: No, rectangular pools require length × width × depth calculation. A different calculator would be needed.

Q4: How do I convert kg to bags of sand?
A: Divide total kg by bag size (typically 25kg or 50kg). Always round up to whole bags.

Q5: What type of sand should I use?
A: Use masonry or pool base sand (not play sand). It should be clean, sharp, and free of debris.
