Soils Inc.

We provide soil investigation services to evaluate the soils for septic designs, stormwater management designs, and geotechnical recommendations. We prepare septic permits for residential and commercial clients. We provide geotechnical reports for residential and light commercial construction as well as to support stormwater management facilities.

Soils Inc. has been evaluating ground conditions since 1988, working out of Marshall, Virginia and across the greater Washington, D.C. metro region. The firm’s work sits at the point where a building or system meets the earth it rests on, which is why its services lean technical rather than cosmetic. More than three decades of investigation in one region gives the company a long read on the soils of northern Virginia and the surrounding capital area, and that history informs how it approaches each new site.
Core services include soil testing and geotechnical investigations, the studies that tell engineers and builders what a site can actually support before design decisions are locked in. Alongside those, the company runs stormwater infiltration studies and stormwater management inspections, groundwater investigations, and septic system layout and inspection. Each of those addresses a different question about a site, from how water moves through the ground to whether a septic system can function where it is proposed.
Testing that supports permits
Much of this work exists to satisfy regulators. When a residential or commercial project needs approval, Soils Inc. provides full soil testing with septic layout suited to health-department submissions, so an application arrives with the field data behind it rather than gaps a reviewer will flag. Stormwater and groundwater investigations serve a similar role, backing up drainage and management designs with measured conditions instead of assumptions, which is exactly what a permit reviewer expects to see.
For developers, engineers and property owners across the region, that combination of testing and documentation turns a regulatory hurdle into a manageable step. The company’s focus stays on subsurface evaluation, which means the people running the tests do this work day in and day out rather than as a sideline to something else. In a region where development pressure runs high, having a firm that knows the local ground and the local approval process removes a good deal of guesswork from the early stages of a project.
