Formula and assumptions
How this calculation works.
Estimate a measured strip area from irregularly spaced stations and left and right offsets. Measured planar area, not earthwork grade selection or drainage design.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.

Measured strip area: 12.5 m²
Offsets vary linearly between supplied stations. Curves and abrupt changes need extra measured stations.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
