Techniseal Polymeric Sand Calculator For Pavers

Polymeric Sand Formula:

\[ \text{Sand (lb)} = \text{Area (ft²)} \times \left(\frac{\text{Joint width (in)} \times \text{Joint depth (in)}}{144}\right) \times 100 \]

1. What is the Polymeric Sand Formula?

The Techniseal polymeric sand calculator estimates the amount of sand needed for paver joints based on area, joint width, and joint depth. This specialized sand hardens when activated with water, creating a durable joint between pavers.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ \text{Sand (lb)} = \text{Area (ft²)} \times \left(\frac{\text{Joint width (in)} \times \text{Joint depth (in)}}{144}\right) \times 100 \]

Where:

\( Area \) — Total area of paved surface 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 — Density factor for polymeric sand (lb/ft³)

Explanation: The equation calculates the volume of joints in cubic feet, then multiplies by the density of polymeric sand to get weight in pounds.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the right amount of polymeric sand - too little won't fill joints completely, while too much is wasteful and expensive.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is polymeric sand better than regular sand?
A: Polymeric sand hardens to resist erosion, weed growth, and insect infestation, while regular sand washes out over time.

Q2: How much extra should I buy?
A: It's recommended to purchase 10-15% more than calculated to account for waste, spillage, and uneven joints.

Q3: Can I use this for different brands of polymeric sand?
A: While designed for Techniseal, this calculator works for most polymeric sands which have similar densities (around 100 lb/ft³).

Q4: What if my joints are irregular?
A: For irregular joints, calculate based on average width and depth, or divide your project into sections with different joint sizes.

Q5: How does joint depth affect sand quantity?
A: Deeper joints require significantly more sand - doubling joint depth doubles the sand required, all else being equal.
