1. What is Polymeric Sand?

Polymeric sand is a mixture of fine sands combined with additives that form a binding agent when activated with water. It's used to fill paver joints, creating a durable, weed-resistant surface that prevents insect infestation and washouts.

2. How the Calculator Works

The calculator uses the following formula:

\[ Cost = Area \times \frac{Joint\ width \times Joint\ depth}{144} \times 100 \times Price\ per\ lb \]

Where:

\( Area \) — Total paver area in square feet
\( Joint\ width \) — Width between pavers in inches
\( Joint\ depth \) — Depth of joints in inches
144 — Conversion factor (square inches to square feet)
100 — Standard density of polymeric sand (lb/ft³)
\( Price\ per\ lb \) — Cost of polymeric sand per pound

Explanation: The formula calculates the volume of sand needed based on joint dimensions, then multiplies by the sand density and price to determine total cost.

3. Importance of Proper Calculation

Details: Accurate calculation ensures you purchase the right amount of polymeric sand, preventing project delays from under-ordering or unnecessary costs from over-ordering.

4. Using the Calculator

Tips: Measure your paver area accurately. Typical joint widths range from 1/8" to 1/2". Joint depth is usually equal to paver thickness minus 1/2" to allow for proper compaction.

5. Frequently Asked Questions (FAQ)

Q1: How much sand do I need per square foot?
A: For 1/4" joints, about 0.17 lb/ft²; for 1/2" joints, about 0.35 lb/ft² (assuming standard depth).

Q2: Can I use this for irregular paver patterns?
A: Yes, but measure average joint width for best results in irregular installations.

Q3: Does joint depth significantly affect cost?
A: Yes, doubling joint depth doubles sand requirements. Always measure actual joint depth.

Q4: Should I add extra for waste?
A: Add 5-10% extra to account for spillage and compaction, especially for large projects.

Q5: How does polymeric sand compare to regular sand?
A: Polymeric sand costs more initially but provides long-term stability and requires less maintenance.
