1. What is Paver Bedding Sand?

Paver bedding sand is a specially graded sand used as a base material for laying pavers. It provides a stable, level surface that allows for proper compaction and drainage.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Sand (kg)} = \text{Area (m²)} \times \text{Depth (m)} \times \text{Density (kg/m³)} \]

Where:

\( Area \) — The surface area to be paved (in square meters)
\( Depth \) — Recommended depth is 0.03 meters (3 cm)
\( Density \) — Standard sand density is 1600 kg/m³

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

3. Importance of Proper Sand Bedding

Details: Correct sand bedding is crucial for paver stability, preventing settling, ensuring proper drainage, and maintaining a level surface over time.

4. Using the Calculator

Tips: Measure your area accurately in square meters. The default depth of 0.03m (3cm) is typical for paver bedding. Adjust density if using special sand types.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical depth for paver bedding sand?
A: Most projects use 25-50mm (0.025-0.05m), with 30mm (0.03m) being most common for residential applications.

Q2: Can I use regular beach sand?
A: No, paver bedding requires coarse, sharp sand that compacts well. Beach sand is too fine and will wash away.

Q3: How much extra sand should I order?
A: Add 10-15% to account for compaction and spillage during installation.

Q4: Does this include joint sand?
A: No, this calculates only bedding sand. Joint sand is additional and calculated separately.

Q5: How many bags will I need?
A: Divide total kg by bag size (typically 25kg or 40kg). Example: 800kg ÷ 25kg = 32 bags.
