Exploring from the surface down to help build from the ground up

Geotechnical Engineering

Legacy Engineering provides comprehensive subsurface explorations across a wide array of project types, specialized laboratory soil analysis, and actionable geotechnical design recommendations across Virginia.

Our engineering team evaluates cost-effective strategies, recommendations, and designs for what and where you want to build. Whether you're looking to capture a specific view from a residential window, establish a market square on a hillside, or redevelop a site to create a new community, Legacy’s engineering team explores what can’t be seen to help your vision come to life.

Problems We Solve

Uncertain Ground Conditions: We identify problematic soil conditions early, including high groundwater, expansive (shrink-swell) soils, shallow rock, acid-sulfate soils, existing fill, and complex natural or man-made site conditions. This allows us to reduce the risk of unexpected site development costs and provide actionable options long before issues arise on site.
Complex Site Conditions: We analyze site plans and environmental conditions to provide targeted engineering solutions and designs for steep slopes, retaining walls, complex foundations, soil stabilization, shallow groundwater, and acid-sulfate mitigation.
Stormwater Management & Regulatory Alignment: Legacy is proud to have participated in updating the Virginia Stormwater Management Handbook. Our combined civil and geotechnical expertise puts us at the forefront of innovative design solutions and construction guidance, helping developers, contractors, and civil engineers meet evolving regulations while mitigating risk. We also perform detailed stability and failure analyses for existing regulated or unregulated ponds and embankment dams.
