Gravity Stone Wall Material Estimate

Range: at least 0.01 ft

Measured wall run.

Range: at least 0.01 ft

Average wall height.

Range: at least 0.01 in

Width at base of trapezoidal section.

Range: at least 0.01 in

Width at top of trapezoidal section.

Range: 0–100 %

Estimate open void area in dry-stack construction; this is not stone porosity. Enter 0 only when intentionally estimating no voids.

Range: at least 0.01 lb/ft3

Use supplier/test data for solid stone, not loose-wall bulk density.
