1. What is the Sharp Sand Calculator?

The Sharp Sand Calculator helps determine the amount of sharp sand needed for patio bedding based on the area to be covered, desired depth, and sand density.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Area \) — The surface area to be covered (in square meters)
• \( Depth \) — The depth of sand layer (typically 0.03m or 30mm for patio bedding)
• \( Density \) — The density of sharp sand (typically 1600 kg/m³)

Explanation: The formula calculates the volume of sand needed and converts it to weight using the sand's density.

3. Importance of Accurate Sand Calculation

Details: Proper sand calculation ensures you purchase the right amount of material, avoiding waste or shortages during patio construction.

4. Using the Calculator

Tips:

• Measure the area accurately in square meters
• Standard depth for patio bedding is 30mm (0.03m)
• Sharp sand typically has a density of 1600 kg/m³
• All values must be positive numbers

5. Frequently Asked Questions (FAQ)

Q1: What is sharp sand used for in patio construction?
A: Sharp sand is used as a bedding layer under paving slabs to provide a stable, well-draining base.

Q2: Why is 30mm the typical depth for patio bedding?
A: 30mm provides adequate support for most paving slabs while allowing for proper compaction and drainage.

Q3: Can I use this calculator for other types of sand?
A: Yes, but you'll need to adjust the density value according to the specific sand type you're using.

Q4: How do I convert the result to bulk bags?
A: Divide the total kg by the weight of a bulk bag (typically 800kg or 850kg per bulk bag).

Q5: Should I order extra sand to account for compaction?
A: It's recommended to add 10-15% to your total to account for compaction and spillage during installation.
