1. What is a Self-Binding Gravel Calculator?

Definition: This calculator estimates the volume of self-binding gravel needed based on the area dimensions and desired depth.

Purpose: It helps landscape professionals and homeowners determine how much self-binding gravel is required for pathways, driveways, and other outdoor surfaces.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of self-binding gravel (cubic yards)
• \( L \) — Length (feet)
• \( W \) — Width (feet)
• \( D \) — Depth (feet)
• 27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator multiplies length by width by depth (converted from inches to feet) and divides by 27 to convert cubic feet to cubic yards.

3. Importance of Self-Binding Gravel Calculation

Details: Accurate volume estimation ensures proper surface preparation, adequate material purchasing, and cost-effective project planning.

4. Using the Calculator

Tips: Enter the length and width in feet, and depth in inches. All values must be > 0. For best results, self-binding gravel is typically installed at 2-3 inches depth.

5. Frequently Asked Questions (FAQ)

Q1: What is self-binding gravel?
A: A specially formulated gravel that binds together when compacted, creating a stable surface without the need for additional binders.

Q2: How deep should I lay self-binding gravel?
A: Typically 2-3 inches for foot traffic, 3-4 inches for vehicle traffic. Always compact thoroughly.

Q3: How much does self-binding gravel weigh?
A: Approximately 1.4-1.6 tons per cubic yard, depending on moisture content and compaction.

Q4: Do I need a sub-base for self-binding gravel?
A: For driveways or heavy use areas, a compacted hardcore sub-base is recommended beneath the gravel.

Q5: Does this include waste or overage?
A: No, consider adding 5-10% to the calculated volume for compaction and project contingencies.
