The short version: the calculators are free planning tools. Their numbers are screening-level estimates built from public data and your inputs, not a survey, not a geotechnical report, and not engineering advice. Verify everything with licensed professionals before you bid, buy, or build.
1. What the calculators are
The Soil Depot calculators (Quick, Full, Earthwork, and Pad and Lot, including plan uploads, AI sheet reading, soil and strata estimates, haul planning, cross sections, phasing, and design file exports) are free planning tools. They produce screening-level estimates to help you scope a job quickly. By using the calculators, or by downloading, sharing, or exporting anything they produce, you agree to these terms.
2. Where the numbers come from, and their limits
Results are computed from public data and from what you enter:
- USGS LiDAR ground elevations, at about 1 meter resolution. LiDAR is a planning surface, not a stamped survey.
- USDA SSURGO soil survey data, mapped at survey scale for a region, not measured at your parcel. It is not a geotechnical investigation.
- Your own inputs: dimensions, depths, outlines you draw, boring logs you type, and files you upload. The tool trusts them as entered.
- AI sheet reading, when you use it, extracts values from your documents. AI can misread a drawing, and every extracted value must be checked against the plan.
- Uploaded plans and design files are read as drawn, which may not match conditions on the ground.
3. Not a survey, not engineering, not professional advice
Nothing the calculators produce is a survey, a geotechnical report, or engineering, architectural, or other professional advice, and using them creates no engineer-client or other professional relationship. Material suitability calls, for example whether a cut can be reused as structural fill, are screening-level classifications from survey data or from the boring logs you type. They are not a substitute for a licensed geotechnical engineer.
4. Machine-control and design file exports
Files you export, including LandXML surfaces for machine control, are generated from planning surfaces, not from a stamped design. Do not stake, grade, or build to an exported file until a licensed engineer or surveyor has reviewed and approved it for construction.
5. As is, no warranty
The calculators and everything they produce are provided as is and as available, without warranty of any kind, express or implied, including any warranty of accuracy, merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that results are correct, complete, or current, or that the tools will be available or error free.
6. Your responsibility to verify
You are solely responsible for verifying every quantity, elevation, soil classification, and cost with a licensed surveyor, a licensed geotechnical engineer, and your own professionals before you bid, purchase, order material, or begin construction. Do not make financial or construction decisions on calculator output alone.
7. Limitation of liability
To the maximum extent permitted by law, Soil Depot and its owners, employees, contractors, and suppliers are not liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, or business, arising from or related to the calculators or these terms, and are not liable for decisions made in reliance on calculator output. To the same extent, Soil Depot's total combined liability arising from the calculators is capped at one hundred US dollars. Some jurisdictions do not allow certain of these limitations, so parts of this section may not apply to you.
8. Estimates are not quotes
Delivered pricing and final quantities are confirmed by Soil Depot for each job. An estimate from the calculators is not a quote, an offer, or a contract. Material purchases and hauling services are separate transactions with their own terms.
9. Governing law and venue
These terms are governed by the laws of the State of Texas, without regard to its conflict of law rules. Any dispute arising from the calculators or these terms must be brought in the state or federal courts located in Collin County, Texas, and you consent to that venue.
10. Changes to these terms
We may update these terms from time to time. Changes take effect when posted on this page, and your continued use of the calculators after changes are posted constitutes acceptance. Questions are welcome at (817) 632-5787.
