1. What is Kiln Dried Sand?

Kiln dried sand is a specially prepared sand used for filling joints between paving stones. It's dried to remove moisture, making it flow easily into joints, and often contains additives to improve stability and prevent weed growth.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Area — The total area to be paved in square meters
• Depth — The depth of the sand layer in meters
• 1600 kg/m³ — The standard density of kiln dried sand

Explanation: The calculation determines the weight of sand needed to fill the joints between paving stones based on the area to be paved and the desired depth of the sand layer.

3. Importance of Proper Sand Calculation

Details: Accurate sand calculation ensures you purchase the right amount of material, avoiding waste or shortage. Proper joint filling is crucial for the stability and longevity of paved surfaces.

4. Using the Calculator

Tips: Measure your paving area accurately in square meters. Typical joint depth is 2-5mm (0.002-0.005m). For irregular areas, divide into rectangles and calculate separately.

5. Frequently Asked Questions (FAQ)

Q1: Why use kiln dried sand instead of regular sand?
A: Kiln dried sand flows better into joints, is free from moisture that could cause shifting, and often contains stabilizing additives.

Q2: What's the typical depth for paving joints?
A: Most paving joints require 2-5mm of sand, but this depends on the paver size and type. Always check manufacturer recommendations.

Q3: How do I convert square feet to square meters?
A: Multiply square feet by 0.0929 to get square meters (1 ft² = 0.0929 m²).

Q4: Should I order extra sand?
A: It's wise to order 10-15% extra to account for spillage, compaction, and irregularities in the surface.

Q5: Can I use this for other types of sand?
A: This calculator uses the density of kiln dried sand (1600 kg/m³). Other sands may have different densities and would require adjustment.
