Polymeric Sand Calculation:
From: | To: |
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 the joints between pavers, bricks, or natural stone in hardscape projects.
The calculator uses the following equation:
Where:
Explanation: The equation calculates the volume of joints in cubic feet, then converts this to weight based on the sand density.
Details: Accurate calculation ensures you purchase the right amount of material, avoiding waste or project delays from insufficient supplies.
Tips: Measure your paved area accurately. For irregular shapes, divide into rectangles. Typical joint widths range from 0.25" to 0.5". Standard density is 100 lb/ft³ unless specified otherwise.
Q1: How much extra sand should I buy?
A: It's recommended to purchase 10-15% more than calculated to account for settling, waste, and uneven joints.
Q2: Can I use this for regular sand?
A: Yes, but density may vary (regular sand is typically 90-100 lb/ft³). Check your product specifications.
Q3: What if my joints are different sizes?
A: Calculate each size separately and sum the results, or use an average width if variations are minor.
Q4: How do I measure joint depth?
A: Measure from the top of the paver to the base material. This is typically slightly less than paver thickness.
Q5: Does this account for compaction?
A: No, the calculation gives loose volume. Polymeric sand compacts about 10-15% when activated with water.
