1. What is Binding Sand for Pavers?

Binding sand (such as polymeric sand) is used to fill joints between pavers, creating a stable, permeable surface that prevents weed growth and insect infestation while allowing for proper drainage.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Area — Total surface area of the paved area in square meters
• Depth — Depth of the sand layer in meters (typically 0.02-0.05m for paver joints)
• 1600 kg/m³ — Standard density for polymeric binding sand

Explanation: The calculation accounts for the volume of sand needed to fill all joints at the specified depth, using standard density for polymeric sand.

3. Importance of Proper Sand Calculation

Details: Accurate sand calculation ensures proper joint filling, which is crucial for paver stability, preventing weed growth, and maintaining proper drainage between pavers.

4. Using the Calculator

Tips: Measure your paved area accurately in square meters. Typical joint depth is 2-5 cm (0.02-0.05 m). The density is fixed at 1600 kg/m³ for standard polymeric sand.

5. Frequently Asked Questions (FAQ)

Q1: How deep should the sand layer be?
A: Typically 2-5 cm (0.02-0.05 m) depending on paver size and joint width.

Q2: Can I use regular sand instead of polymeric sand?
A: Regular sand can be used but won't provide the binding and weed prevention of polymeric sand.

Q3: How do I convert square feet to square meters?
A: Multiply square feet by 0.0929 to get square meters.

Q4: Should I order extra sand?
A: It's recommended to add 5-10% to account for settling and waste.

Q5: How does joint width affect sand quantity?
A: Wider joints require more sand. The calculator accounts for this through the depth parameter.
