1. What is Kiln Dried Sand?

Kiln dried sand is a specially prepared sand used for block paving joints. It's dried to remove moisture, making it free-flowing and perfect for filling gaps between paving blocks.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Area \) — Paving area in square feet
• \( Depth \) — Depth of sand layer in feet
• \( 100 \) — Density of kiln dried sand (lb/ft³)

Explanation: The calculation accounts for the volume of sand needed and its standard density to give weight in pounds.

3. Importance of Proper Sand Calculation

Details: Accurate sand calculation ensures proper joint filling, prevents weed growth, and maintains the stability of your block paving.

4. Using the Calculator

Tips: Measure your paving area accurately in square feet. Typical sand depth is 0.02-0.04 feet (¼-½ inch) for block paving joints.

5. Frequently Asked Questions (FAQ)

Q1: Why use kiln dried sand specifically?
A: Kiln dried sand is moisture-free, preventing weed growth and ensuring it flows easily into joints.

Q2: How much sand do I need for standard block paving?
A: Typically 25-50 lb per 100 ft² for ¼-½ inch joints, but always calculate for your specific project.

Q3: Can I use regular sand instead?
A: Not recommended - regular sand may contain moisture and organic matter that can lead to weed growth.

Q4: How do I apply the sand?
A: Spread evenly over the paved area and sweep into the joints with a stiff brush.

Q5: Should I compact the sand?
A: Light compaction with a plate compactor is recommended after initial brushing to settle the sand.
