Engineering stability for British Columbia's most demanding terrain.
Site investigation, analysis, and construction support for builders, municipalities, and industry — from Fraser delta silts to Coast Mountain rock.
Geotechnical professional services
Local knowledge of BC geology and the permit process — from a single-lot investigation to pit-wall modelling.
Slope Stability & Landslide Risk
Slope stability analysis, rockfall hazard assessment, and remediation design for natural and cut slopes in the Lower Mainland corridors and coastal mountains.
DetailsGeotechnical Site Investigations
Borehole drilling, CPT, geophysical surveys, and in-situ testing. Detailed geotechnical reports for foundations, tunnels, pipelines, and major infrastructure.
DetailsFoundations & Earthworks
Shallow and deep foundation design, ground improvement, excavation shoring, and dewatering for urban, industrial, and hillside sites.
DetailsDeep Excavation & Shoring
2D and 3D finite-element analysis and design of complex deep excavations and shoring systems in tight urban sites.
DetailsSeismic & Ground Improvement
Site-specific seismic hazard, liquefaction triggering, and performance-based design for infrastructure in the Cascadia subduction zone.
DetailsMining Geomechanics & Tailings
Pit slope design and optimization, underground ground support, tailings storage facility support, and regulatory compliance for BC mines.
DetailsOne practice, four kinds of site
Builders & developers
Building permits, steep-slope DPAs, foundations, and construction reviews that keep housing moving.
Municipal & infrastructure
Watermains, chambers, roads, and public works where constructability and neighbour impact matter.
Mining & industrial
Pit slopes, tailings, heavy tanks, and plant foundations — from investigation through monitoring.
Energy & marine
LNG, terminals, and waterfront works on soft deltaic soils and high-seismicity ground.
Featured projects
Representative assignments across mining, municipal works, energy, and steep terrain.
Slope Stabilization Program
Full geotechnical investigation, design, and construction support for 2.4 km of high-risk rock cuts — rock bolting, draped mesh, and drainage.
Pit Wall Optimization & Monitoring
3D limit-equilibrium and numerical analysis to steepen final pit walls by 8°, with real-time radar and prisms for safety-critical monitoring.
Watermain Chamber & Shoring
Excavation and installation of a slide-rail shoring system with vibration and acoustic monitoring next to live municipal infrastructure.
Ground Improvement & Seismic Analyses
CPT and sonic drilling campaign with liquefaction triggering assessment for a critical LNG facility expansion on soft deltaic soils.
Local expertise. Global standards.
Founded in 2015, Earthtec is a Vancouver-based firm of professional engineers and geoscientists who live and work in the landscapes we study. Our experience, knowledgeable staff, and high level of support have made us a top choice for British Columbia's construction and development industries. Additionally, our local affiliations allow us to draw on a fully equipped CCIL-certified materials testing laboratory as well as support staff for our projects.
We combine rigorous technical analysis with practical construction experience. Our clients include major mining companies, provincial agencies, municipalities, and leading developers who rely on us for technically sound, regulatorily defensible, and constructible solutions.
Working together with our clients and community, our goal is to develop geotechnical engineering solutions that are cost-effective and delivered in a timely manner.
From brief to field review
A short path that matches how building departments and contractors actually move.
- 01
Brief
Send drawings or call the office. We confirm scope, timeline, and what the municipality actually needs signed.
- 02
Investigate
Test holes, CPT, mapping, or a focused desktop review — sized to the risk, not to a template.
- 03
Analyze & design
Limit equilibrium, FEA, seismic, or bearing calculations. Complexity only where the ground demands it.
- 04
Report & assure
Clear recommendations, drawings, and Letters of Assurance that building departments will accept.
- 05
Field support
Excavation reviews, monitoring, and prompt redesign when soil conditions change during construction.
