1. What is a Paver Base Gravel Calculator?

Definition: This calculator estimates the weight of gravel needed for paver base based on area, depth, and gravel density.

Purpose: It helps landscape professionals and DIYers determine how much gravel is required for paver installation projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of gravel (tons)
• \( A \) — Area to be covered (square feet)
• \( D \) — Depth of gravel base (feet)
• \( \rho \) — Density of gravel (pounds per cubic foot, typically 100-130)

Explanation: The area multiplied by depth gives volume, multiplied by density gives weight in pounds, divided by 2000 converts to tons.

3. Importance of Paver Base Calculation

Details: Proper gravel base ensures stable paver installation, prevents settling, and provides proper drainage beneath pavers.

4. Using the Calculator

Tips: Enter the area in square feet, depth in feet (typically 0.25-0.5 ft for paver bases), and gravel density (default 100 lb/ft³). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical depth for paver base?
A: Most paver installations require 4-6 inches (0.33-0.5 ft) of compacted gravel base.

Q2: Why does density vary?
A: Gravel density ranges from 100-130 lb/ft³ depending on material type (crushed stone vs. rounded gravel) and moisture content.

Q3: Should I account for compaction?
A: Yes, the calculated amount is for compacted gravel. You may need 10-15% more material to account for compaction loss.

Q4: How do I measure the area?
A: For rectangular areas: length × width. For irregular shapes, break into rectangles or use our Area Calculator tool.

Q5: Does this include sand for leveling?
A: No, this calculates only the gravel base. You'll need additional sand (typically 1 inch) for the leveling layer.
