1. What is Paver Sand Calculation?

The paver sand calculation determines the amount of sand needed for proper bedding under pavers or stone tiles. A correct sand base ensures proper leveling, drainage, and stability for your paved surface.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Area — The surface area to be paved (in square meters)
• Depth — The depth of sand bedding required (in meters)
• 1600 — Standard density of paver sand (in kg/m³)

Explanation: The formula calculates the volume of sand needed (area × depth) and converts it to weight using standard sand density.

3. Importance of Proper Sand Bedding

Details: Proper sand bedding is crucial for paver installation. It provides a stable base, allows for proper leveling, facilitates drainage, and helps prevent shifting or settling of pavers over time.

4. Using the Calculator

Tips: Measure your project area accurately in square meters. Typical sand bedding depth is 25-50mm (0.025-0.05m). Always add 5-10% extra to account for compaction and spillage.

5. Frequently Asked Questions (FAQ)

Q1: What type of sand should I use for paver bedding?
A: Use coarse, sharp sand or specifically labeled "paver sand" that compacts well without becoming too hard.

Q2: How deep should the sand layer be?
A: Typically 25-50mm (1-2 inches), but check manufacturer recommendations for your specific pavers.

Q3: Do I need to compact the sand?
A: Yes, proper compaction is essential for a stable base. Use a plate compactor for best results.

Q4: Should I put anything under the sand?
A: A geotextile fabric and/or crushed stone base is recommended in many installations, especially in areas with poor drainage.

Q5: Can I use this calculator for other materials?
A: This calculates specifically for sand (1600 kg/m³). Other materials have different densities and would require adjustment.
