1. What is the Patio Paver Sand Calculator?

The Patio Paver Sand Calculator estimates the amount of sand needed for paver bedding based on the area to be covered, desired depth, and sand density. Proper sand bedding is crucial for a stable and long-lasting patio surface.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Area \) — Area to be covered in square meters
• \( Depth \) — Depth of sand bedding in meters (typically 0.03m or 30mm)
• \( 1600 \) — Standard density of paver sand in kg/m³

Explanation: The calculation accounts for the volume of sand needed (area × depth) multiplied by the density to convert to weight.

3. Importance of Proper Sand Bedding

Details: A proper sand base provides stability, helps with leveling, allows for drainage, and prevents shifting or settling of pavers over time. The standard depth is typically 25-40mm (0.025-0.04m).

4. Using the Calculator

Tips: Measure your area accurately in square meters. The default depth of 0.03m (30mm) is recommended for most patio applications. The standard sand density is 1600 kg/m³ but may vary slightly depending on sand type.

5. Frequently Asked Questions (FAQ)

Q1: What type of sand should I use for paver bedding?
A: Use coarse, sharp sand or concrete sand (not play sand or masonry sand) that compacts well.

Q2: How much sand do I need for a 10m² patio?
A: At 30mm depth: 10 × 0.03 × 1600 = 480kg (about 24 standard 20kg bags).

Q3: Should I use a sand calculator for gravel as well?
A: No, gravel has different density (typically about 1500 kg/m³) and different depth requirements.

Q4: How do I convert the result to number of bags?
A: Divide the total kg by the bag size (typically 20kg or 25kg bags are common).

Q5: Do I need to account for compaction?
A: The calculation includes typical compaction, but very sandy soils may require slightly more.
