Planning estimates only
Every result on Terrainity is an estimate built from the measurements and options you enter and from typical values for material weight, coverage, waste and compaction. Real projects differ. Confirm quantities, sizes and prices with your supplier or contractor before you order.
Not professional advice
The calculators and guides are general information. They do not replace a licensed surveyor, engineer, landscape architect, contractor or your local building department. Fences on a property line, retaining walls, decks, driveways, pools and grading can need permits, inspections or engineering. Call 811 before you dig.
Accuracy and sources
We source our numbers from university extension services, industry institutes, government agencies and manufacturers, and we try to keep them current. We can't promise that every figure is free of error or fits your site, so check a result that looks wrong against your supplier's data sheet.
Limit of liability
Terrainity is provided “as is”, without warranty. We are not responsible for losses, extra materials, delays or damage resulting from the use of a result. See also our terms of use.
