1. What Is Techniseal Polymeric Sand?

Techniseal polymeric sand is a high-quality jointing material used for filling the joints between pavers. While Techniseal doesn't have a unique formula, this calculator uses the standard polymeric sand calculation method.

2. How Does the Calculator Work?

The calculator uses the standard polymeric sand formula:

Where:

• \( Area \) — Paving area in square feet
• \( Joint Width \) — Width between pavers in inches
• \( Joint Depth \) — Depth of joints in inches
• 162 — Conversion factor (cubic inches to pounds)
• 1.1 — 10% safety factor

Explanation: The formula calculates the volume of joints and converts it to weight with a safety margin.

3. Importance of Proper Sand Calculation

Details: Accurate calculation ensures you purchase the right amount of polymeric sand, preventing waste or shortage during installation.

4. Using the Calculator

Tips: Measure your paved area accurately. Typical joint widths are 1/4" to 1/2". Joint depth is usually equal to paver thickness minus 1/2".

5. Frequently Asked Questions (FAQ)

Q1: How much extra sand should I buy?
A: The calculator includes a 10% safety factor. You may want additional 5-10% for complex patterns.

Q2: What's the average coverage rate?
A: Approximately 1 lb per 1-2 sq ft for 1/4" joints, but varies significantly with joint dimensions.

Q3: Can I use this for irregular patterns?
A: Yes, but measure carefully. For very irregular patterns, add 15-20% extra.

Q4: Does joint depth affect stability?
A: Yes, joints should be filled to within 1/2" of the paver top for proper locking.

Q5: How does Techniseal compare to other brands?
A: Techniseal offers premium quality with reliable performance, though calculation method is standard across brands.
