FAQ · Washington County

Do I need a geotechnical report before building?

Most commercial permits, lenders, and structural engineers require a geotechnical report to establish allowable bearing pressure and foundation type. It is the least expensive insurance a foundation can have.

How long does a geotechnical investigation take?

A typical light-commercial site runs one to two weeks from drilling to final report, depending on lab test turnaround and access conditions.
