Geotechnical Engineering in Campbell County, WY

Northeast Wyoming soils commonly include fine-grained clays and silts with variable plasticity, which can exhibit shrink-swell behavior. Where expansive soils are confirmed through Atterberg limit testing (ASTM D4318) and swell-consolidation testing (ASTM D4546), foundation design typically addresses potential heave through over-excavation and replacement, moisture conditioning, or structurally isolated slabs. A site-specific investigation determines which condition applies to your project.

Sites near historic surface or underground coal operations may require investigation for disturbed fill, subsidence potential, or irregular subsurface conditions not detectable by standard borings alone. Investigation scopes in these areas often include deeper borings, closer spacing, and review of available mine maps. The geotechnical engineer of record determines the appropriate scope; we collect the subsurface data and perform the laboratory testing needed to support that evaluation.

Gillette's semi-arid climate brings cold winters and significant diurnal temperature variation year-round. Earthwork and proof-rolling are best completed when soils are near optimum moisture and not frozen. For concrete work tied to geotechnical recommendations—such as lean concrete fills or grade beams—cold-weather concrete procedures per ACI 306R apply when ambient temperatures fall below 40°F, which is common from October through April in this region.

Field work in Campbell County is dispatched through the Denver, CO regional hub, about 316 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Campbell County projects.

Field sampling and testing in Campbell County are performed by our ACI- and NICET-certified technicians. Geotechnical engineering and professional services are delivered with professionals licensed in Wyoming, coordinated under one proposal.
