1. What is the Pebble Coverage Calculator?

The Pebble Coverage Calculator estimates the amount of pebbles required to cover a specific area based on depth and density. It is specifically designed for UK pebble measurements and standards.

2. How Does the Calculator Work?

The calculator uses the coverage formula:

Where:

• \( Area \) — Surface area to be covered (m²)
• \( Depth \) — Depth of pebble layer (mm)
• \( Density \) — Density of pebbles (kg/m³)

Explanation: The formula calculates the weight of pebbles needed by considering the volume (area × depth) and material density.

3. Importance of Pebble Coverage Calculation

Details: Accurate pebble coverage calculation is essential for landscaping projects, ensuring you purchase the correct amount of materials and avoid wastage or shortages.

4. Using the Calculator

Tips: Enter area in square meters, depth in millimeters, and density in kilograms per cubic meter. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density for UK pebbles?
A: Density varies by pebble type, but generally ranges from 1600-1800 kg/m³ for most decorative pebbles.

Q2: How do I measure the area accurately?
A: Measure length and width in meters and multiply them together. For irregular shapes, break into regular sections and sum the areas.

Q3: What depth is recommended for different applications?
A: For decorative purposes, 25-50mm is typical. For functional purposes like drainage, 50-75mm may be required.

Q4: Should I order extra pebbles?
A: It's recommended to order 10-15% extra to account for settling, compaction, and irregularities in coverage.

Q5: Can this calculator be used for other materials?
A: While designed for pebbles, it can be adapted for other granular materials by adjusting the density value accordingly.
