About Us

Founded in 1981, So-Deep is recognized as the original Subsurface Utility Engineering company. Our vision then and today remains the same: to provide accurate and reliable data on the existence and location of underground utilities. Through our refinement of how utilities are mapped and documented, we created the engineering profession known as SUE.

As part of our ongoing effort to expand services, capabilities, and geographic range, in 2016 So-Deep became part of the SAM family of companies. Along with our sister companies Surveying And Mapping, LLC (SAM), SAM–Construction Services, LLC, (SAM-CS), and SO-DEEP | SAM NC, Inc., we're now part of a team that delivers a full range of geospatial services, from above ground and below.
