Geotechnical engineering is a branch of civil engineering focused on understanding the behavior of soil, rock, and groundwater beneath the Earth’s surface. It applies principles of soil mechanics, rock mechanics, and geology to evaluate ground conditions and design safe, stable infrastructure.
Geotechnical engineers play a critical role in projects involving foundations, slopes, retaining structures, embankments, tunnels, and earthworks, ensuring that everything built above ground is supported by what lies beneath.
At DMC, geotechnical engineering is at the core of what we do. Our team delivers expert support across all project phases from desktop studies and site investigations to design development and construction oversight. We specialize in:
A geotechnical desktop study is a preliminary review of existing information to understand subsurface conditions before any fieldwork begins. It helps identify potential constraints, guide investigation planning, and provide early context for design decisions.
Foundation design is the process of determining how a structure will safely transfer its loads to the ground. In geotechnical engineering, this means understanding the interaction between soil, rock, groundwater, and structural demands—then selecting a foundation system that suits both the site and the project.
Retaining walls are engineered structures that resist lateral earth pressures and maintain differences in ground elevation. In geotechnical design, they serve a wide range of functions—from supporting road cuts and basement excavations to stabilizing slopes and creating usable flat areas on steep terrain.
Geohazards are natural or human-influenced geological processes that pose risks to infrastructure, ecosystems, and public safety. In British Columbia, where steep terrain, seismic activity, and variable climate converge, identifying and managing these hazards is essential for safe development and long-term resilience.

Slope stability assessments are a core part of geotechnical engineering, especially in regions like British Columbia where terrain varies from steep coastal bluffs to glacial valleys and urban embankments. These evaluations help determine whether natural or constructed slopes are likely to remain stable under current and future conditions.
Soft soils are extensive across BC from compressible Still Creek peat and marine clays to soft glaciolacustrine deposits in Northeast BC. These soils require a comprehensive understanding of settlement analysis. This is the process of estimating how much and how quickly the ground beneath a structure or embankment will compress under load.
Seismic design is a critical component of geotechnical engineering, especially in seismically active regions like British Columbia. It focuses on how soil and rock respond to earthquake-induced ground motion—and how those responses affect the stability and performance of foundations, slopes, and retaining structures.
Retaining walls are engineered structures that resist lateral earth pressures and maintain differences in ground elevation. In geotechnical design, they serve a wide range of functions—from supporting road cuts and basement excavations to stabilizing slopes and creating usable flat areas on steep terrain.
Embankment design involves constructing raised earth structures—typically for roads, railways, flood protection, or site grading that safely support loads and resist deformation over time.
In British Columbia, embankments can be supported on a diverse range of geotechnical conditions, from peat/muskeg soils to soft marine clays and organic silts to dense glacial tills and fractured bedrock.
Rock mechanics is the study of how rock masses behave under stress—essential for designing safe excavations in tunnels, slopes, foundations, and underground structures.
