1. What is Paver Sand?

Paver sand is a specific type of sand used as a base material for installing pavers. It provides stability, proper drainage, and helps level the surface before laying pavers. Home Depot recommends using this calculation for proper paver installation.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Area \) — The surface area to be covered with pavers (square meters)
• \( Depth \) — The depth of sand layer needed (meters)
• \( 1600 \) — Standard density of paver sand (kg/m³)

Explanation: The calculation determines the weight of sand needed based on volume and standard density.

3. Importance of Proper Sand Base

Details: A proper sand base is crucial for paver stability, preventing shifting, ensuring proper drainage, and creating a level surface for your pavers to rest on.

4. Using the Calculator

Tips: Measure your project area accurately in square meters. The typical sand depth for paver bases is 25-50mm (0.025-0.05m). Always round up your sand quantity to account for compaction and settling.

5. Frequently Asked Questions (FAQ)

Q1: What type of sand should I use for pavers?
A: Use coarse, granular sand specifically labeled as "paver sand" or "base sand" - not play sand or masonry sand.

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

Q3: Do I need to compact the sand?
A: Yes, after spreading, the sand should be lightly compacted before laying pavers to prevent settling.

Q4: Should I put gravel under the sand?
A: For most installations, a gravel base (75-100mm) is recommended beneath the sand layer for better drainage and stability.

Q5: How much extra sand should I buy?
A: It's recommended to purchase 10-15% more than calculated to account for compaction, spillage, and leveling adjustments.
