1. What is the Sand Calculation For?

This calculator determines the amount of sand needed to create a proper base for a swimming pool. The sand layer (typically 5cm/0.05m deep) provides a smooth, level surface that protects the pool liner.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Area — Pool base area in square meters
• Depth — Sand layer depth in meters (typically 0.05m)
• 1600 — Sand density in kg/m³

Explanation: The calculation accounts for the volume of sand needed and converts it to weight using standard sand density.

3. Importance of Proper Sand Base

Details: A properly prepared sand base prevents liner damage, ensures even weight distribution, and helps maintain proper pool structure. Too little sand can lead to punctures, while too much can cause settling issues.

4. Using the Calculator

Tips: Measure your pool's area accurately. For rectangular pools: length × width. For round pools: π × radius². The default depth of 0.05m (5cm) is standard for most above-ground pools.

5. Frequently Asked Questions (FAQ)

Q1: What type of sand should I use?
A: Use masonry sand or pool filter sand - it's washed, graded, and free of debris. Avoid play sand or beach sand.

Q2: Is 5cm depth always sufficient?
A: For most above-ground pools, yes. For uneven ground or heavy pools, consult your pool manufacturer's recommendations.

Q3: How do I measure an oval pool?
A: Calculate as rectangle (length × width) then multiply by 0.8 for approximate area.

Q4: Does sand density vary?
A: Standard density is 1600 kg/m³. Very wet or compacted sand may be slightly denser.

Q5: Should I add extra sand?
A: It's recommended to purchase 10-15% extra to account for compaction and leveling.
