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.
690+ projects built on trust
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
Analysis, rockfall, and remediation for natural and cut slopes.
Geotechnical Site Investigations
Drilling, CPT, mapping, and reports sized to the problem.
Foundations & Earthworks
Shallow, deep, and improved ground for real BC soils.
Deep Excavation & Shoring
Staged shoring, adjacent-structure protection, and FEA.
Seismic & Ground Improvement
Liquefaction, Cascadia hazard, and ground treatment.
Mining Geomechanics & Tailings
Pit slopes, underground support, and TSF support.
One 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.
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.
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.
