Every load of soil that leaves a construction site carries a compliance obligation — and if you can't prove where it went, that exposure lands on you.
California holds owners and contractors accountable for the soil they move. CALGreen requires 65% construction and demolition diversion. SB 1383 and CalRecycle mandate C&D recovery. DTSC expects documented, clean imported fill. County ordinances in Los Angeles, Orange, and San Diego push toward 100% accountability for excavated soil — with refundable deposits, performance guarantees, and compliance reports gating project closeout. Miss the documentation and the consequences are real: forfeited deposits, projects that can't close, cross-contamination liability, and cradle-to-grave responsibility that can follow you for years.
Dirt ID is the compliance chain of custody for soil. It replaces paper haul tickets with a verified, tamper-evident record for every load, from the approved source to the receiving facility, retained for the life of the project and beyond.
At the center of every load is GPS-verified proof of where the soil actually went. When a load departs the approved source and arrives at the approved facility, Dirt ID captures GPS coordinates and a timestamp, then validates each against the correct approved location — coordinate-and-time evidence that holds up under audit. This is verification, not surveillance: it proves the load reached the right place; it does not track drivers or monitor routes.
One QR-based Soil Passport ties it together — permits, lab testing, environmental approvals, GPS location verification, and facility validation in a single auditable record owners, contractors, consultants, agencies, and facilities can defend long after closeout.
Built for California. Ready for everywhere. Proof over paper. Certainty over risk.
