Total Weight of Rock: pounds
The French Drain Rock Calculator is an invaluable tool designed to streamline the process of determining the amount of rock needed for a French drain installation. French drains, known for their effectiveness in redirecting water away from structures, require specific calculations to ensure optimal performance. This calculator simplifies the complex task of estimating the volume and weight of rock required for a given drainage project.
Formula of French Drain Rock Calculator
The calculation involves two crucial steps:
Volume of Trench (in cubic yards): V=(L×W×D) / 27
Where:
V is the volume of the trench in cubic yards.
L is the length of the trench in feet.
W is the width of the trench in feet.
D is the depth of the trench in feet.
Total Weight of Rock (in pounds): Total Weight = Volume of Trench × Weight per Cubic Yard of Rock
The weight per cubic yard varies based on the type of rock:
Crushed Stone: ~2,750 pounds per cubic yard.
Limestone (Solid): ~2,500 pounds per cubic yard.
Sandstone (Solid): ~2,300 pounds per cubic yard.
Granite (Solid): ~2,750 pounds per cubic yard.
Basalt (Solid): ~2,950 pounds per cubic yard.
River Rock: ~2,600 pounds per cubic yard.

Example of French Drain Rock Calculator
Let’s consider a practical example to illustrate the usage of the French Drain Rock Calculator:
- Input:
- Length (L): 20 feet
- Width (W): 5 feet
- Depth (D): 3 feet
- Rock Type: Crushed Stone
- Calculation:
- V=(20×5×3) / 27 ≈ 37.04 cubic yards
- Total Weight = 37.04×2,750 pounds
- Output:
- Total Weight of Rock: Approximately 101,810 pounds
