INVESTIGATING THE GROUND BENEATH EVERY PROJECT.
Site Investigation Services
We provide geotechnical site investigation services across urban, mountainous, and remote or northern environments, planning and executing complex subsurface exploration programs under demanding environmental, logistical, and safety constraints. Programs begin with a desktop review of regional geology, mapping, imagery, and well data, then are tailored to site conditions and project objectives. Field work is directed by PRI engineers and geoscientists, with drilling, in-situ testing, and geophysical services delivered by qualified specialty contractors, and the resulting data is interpreted to characterize subsurface conditions, evaluate risks, and inform design recommendations.
Talk to an ExpertFoundations & Soil-Structure Interaction
Our foundation engineering and soil-structure interaction services support buildings, bridges, transportation infrastructure, substations, transmission facilities, renewable energy projects, and heavy industrial developments. We evaluate how soil and rock conditions influence foundation performance and develop practical, cost-effective solutions suited to each project's loading requirements, performance criteria, and constructability considerations.

WHERE EVERY STRUCTURE FINDS ITS FOOTING.
TRANSPORTATION & INFRASTRUCTURE
Slopes, Embankments & Earthworks
We provide slope engineering, embankment design, and earthworks services for infrastructure, resource, transportation, and development projects, focusing on how ground behaves under construction and operational conditions to develop solutions that achieve the required safety, performance, and constructability. These services apply wherever stability, settlement, deformation, groundwater conditions, staged construction, or long-term performance govern project design and risk.
Talk to an ExpertRetaining Structures & Excavation Support
We provide retaining structure and excavation support services for developments, transportation infrastructure, industrial facilities, and constrained urban sites, managing earth pressures, groundwater conditions, deformation, and constructability requirements while safeguarding the safety and performance of adjacent infrastructure and existing development.

STABILITY WHEN THE MARGIN FOR ERROR IS ZERO.
PAVEMENT SOLUTIONS DESIGNED TO GO THE DISTANCE.
Pavement Engineering & Transportation Infrastructure
We provide pavement engineering services for transportation, municipal, industrial, commercial, and resource sector projects, covering investigation, design, rehabilitation, and performance assessment for new and existing infrastructure. Recommendations are developed based on subsurface conditions, material properties, traffic loading, environmental factors, and project performance requirements.
Talk to an ExpertGeohazard Assessment & Mitigation Planning
We provide geohazard assessment and mitigation planning services for infrastructure and development exposed to terrain, slope, and erosion-related hazards, focusing on hazard mechanisms, spatial extent, triggering conditions, and consequences to develop proportionate, risk-informed mitigation strategies. These services are typically applied where standard geotechnical design approaches are insufficient to address site-specific hazard exposure or consequence.

READING THE TERRAIN. ANTICIPATING THE RISK.
WHERE WATER MEETS GROUND, WE ENGINEER THE BALANCE.
Hydrogeological, Hydrotechnical & Climate Resilience
We provide geotechnical support for dams, dikes, levees, tailings facilities, and other water-retaining structures, including foundation characterization and treatment, stability and deformation assessment, seepage evaluation, groundwater and surface water interactions, flood and inundation studies, and support for rehabilitating or upgrading existing infrastructure. Climate-related effects — including changes in groundwater conditions, flood hazards, and sea level rise — are considered where relevant to support long-term resilience and performance.
Talk to an ExpertSeismic Design & Geotechnical Earthquake Engineering
We provide geotechnical earthquake engineering services for infrastructure in seismically active regions, with seismic capability integrated across municipal, transportation, water resources, energy, and building projects to support new construction, rehabilitation, and upgrade works.

BUILT TO STAND WHEN THE EARTH SHIFTS.
TURNING DESIGN INTENT INTO BUILT RESULTS.
Construction Services
We provide construction-phase geotechnical services to support safe, efficient, and compliant project delivery, managing ground-related risks, verifying that subsurface conditions and constructed works align with design assumptions, and providing practical solutions when field conditions differ from those anticipated. These services span the full project delivery cycle, from pre-construction planning and tender support through construction, commissioning, and close-out.
Talk to an ExpertField and Laboratory Testing
We provide field and laboratory testing services to support geotechnical investigations, engineering design, construction quality assurance, and performance verification, tailoring testing programs to project requirements and integrating them with our geotechnical engineering services to develop representative design parameters and verify material performance.
