Methodology

Transparent calculation

BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.

Strips per slope and length segments per strip are rounded independently after accounting for side and end overlap. Those layout counts are multiplied by the number of slope sections, then the entered allowance is applied and the order is rounded to full rolls.

FAQ

Erosion Control Blanket Calculator questions

Should rolls run up-and-down or across the slope?+

Installation direction depends on the product and erosion-control detail. Follow the approved plan and manufacturer instructions.

Why is nominal purchased area larger than effective coverage?+

Overlaps, anchor trenches and full-roll rounding reduce the area that each roll can cover in the field.

Does the staple density stay constant?+

No. Steeper slopes, channels, loose soil and high-flow areas may require closer anchoring.
