Our Services

At GS Geotechnical, we deliver tailored geotechnical engineering services with a focus on precision, safety, and compliance. From site investigation to design and construction monitoring, our experienced team ensures every phase meets the highest standards.

We conduct geotechnical site investigations to evaluate subsurface conditions and gather essential data for design and construction. Our services include drilling, test pitting, in-situ testing, and groundwater monitoring supporting residential, commercial, and industrial projects, as well as municipal permitting and development requirements.

We provide foundation engineering services tailored to site-specific soil conditions and structural requirements. Our expertise includes shallow and deep foundation design, settlement analysis, and bearing capacity assessments. We support residential, commercial, and industrial projects with practical, code-compliant solutions that optimize performance and cost.

We perform laboratory and field testing of soil and aggregate materials to assess strength, compaction, classification, and suitability for construction. Our testing supports foundation design, earthworks, and quality control on residential, commercial, and infrastructure projects. 

We provide geotechnical evaluations for residential projects from the early feasibility and permitting stage through to construction and project completion. Our services support single-family homes, duplexes, townhouses, multi-family developments, and subdivision projects.

We provide geotechnical evaluations for commercial projects from initial planning and permitting through to construction and final occupancy. Our services support office buildings, retail plazas, institutional developments such as schools and hospitals, and mixed-use buildings—helping ensure code compliance, cost-effective foundation solutions, and construction efficiency.

We provide geotechnical evaluations for industrial projects from site selection and feasibility through to construction and operational readiness. Our services support warehouses, manufacturing plants, utility infrastructure, and other heavy-use facilities, delivering solutions focused on load-bearing performance, ground stability, and long-term durability to meet the rigorous demands of industrial operations.

We provide geotechnical evaluations for agricultural developments and farm use structures, including barns, greenhouses, silos, storage buildings, and equipment shelters. Our services are tailored to support projects on Agricultural Land Reserve (ALR) lands, where site conditions and regulatory considerations often require specialized solutions. We offer ground improvement techniques such as preloading to manage settlement and improve soil performance, ensuring long-term stability and functionality of agricultural facilities.

We specialize in geotechnical solutions for sites underlain by soft or compressible soils, where conventional construction methods may lead to excessive settlement or instability. Our services include detailed site characterization, settlement analysis, and the design of ground improvement techniques such as preloading, lightweight fills, and pile foundations. Whether supporting roadways, buildings, utilities, or infrastructure, we provide cost-effective strategies to enhance ground performance, reduce construction risk, and ensure long-term stability in challenging soil conditions.

We provide geotechnical assessments and engineering solutions for natural and man-made slopes to ensure long-term stability and safety. Our services include detailed slope stability analyses, setback assessments, and design of stabilization measures such as retaining walls, soil anchors, geogrid reinforcement, and regrading. We support residential, commercial, and infrastructure projects on sloped terrain and steep sites. Our work helps mitigate landslide risks, reduce erosion, and meet municipal development requirements particularly in geotechnically sensitive areas.

We provide geotechnical design and review services for temporary excavation support systems to ensure safe and efficient construction below grade. Our services include shoring design for a variety of systems such as shotcrete with anchor tiebacks, soldier pile and lagging walls. We evaluate soil conditions, groundwater levels, and adjacent structures to develop practical and cost-effective solutions that minimize ground movement and protect surrounding infrastructure. Our work supports deep basements, parkades, utility trenches, and other excavations.

We offer comprehensive geotechnical services for pavement design, evaluation, and condition assessment across municipal, commercial, and industrial projects. Our expertise in transportation geotechnics allows us to provide cost-effective pavement structures tailored to subgrade conditions, traffic loading, and performance requirements. Services include new pavement design, rehabilitation strategies, and visual condition surveys. Whether for roads, parking lots, or heavy-use yard areas, we help clients extend pavement life, reduce maintenance costs, and meet design standards.

We deliver detailed geotechnical reports, drawings, and technical specifications to support permitting, design, tendering, and construction phases of your project. Our reports include subsurface characterization, foundation recommendations, slope stability analysis, seismic site classifications, excavation and shoring guidelines, and construction considerations. Our documentation is developed to facilitate coordination with the full design team including architects, civil engineers, and structural engineers, while meeting municipal, provincial, and regulatory requirements.

We provide geotechnical design and drawings for a variety of retaining wall systems, including gravity, cantilevered concrete, and geogrid-reinforced walls. Our services cover stability analysis, drainage, and coordination with the design team to ensure safe, cost-effective solutions that meet municipal requirements and support efficient construction.

We provide geotechnical construction monitoring and field reviews to confirm that site conditions align with design compliance and minimize project risks. 

We offer geotechnical consulting and advisory services to support planning, design, and construction decision-making. Whether you need preliminary input, peer review, or project-specific guidance, we work closely with clients and design teams to provide practical, experience-based solutions.

FAQs

Have questions about our services or how geotechnical engineering supports your project? We’ve answered some of the most common inquiries to help guide you through the process. 

Geotechnical engineering is the study of soil, rock, and groundwater to assess how they interact with structures like buildings, roads, and retaining walls.

It helps ensure structures are built on safe and stable ground, reducing risks like settlement, foundation failure, or slope instability. 

Geotechnical engineers evaluate ground conditions, conduct soil and rock testing, and provide design recommendations for foundations, retaining walls, slopes, and other earth-related structures. 

We offer geotechnical engineering services for residential, commercial, and infrastructure projects, including foundations, retaining walls, shoring, pavement design, slope stability, and site servicing tailored to your project’s needs.  

A geotechnical site investigation involves soil sampling, testing, and analysis to assess ground conditions. It’s essential for determining the most suitable foundation design and for identifying potential risks such as settlement, slope instability, or soil liquefaction. Proper investigation helps reduce construction risks and costly delays. 

Yes. We provide detailed, professional geotechnical reports that are sealed by a licensed Professional Engineer (P.Eng.), which are accepted by municipalities across British Columbia for building permit submissions.

Yes. We can provide geotechnical related drawings such as typical sections, retaining wall details, shoring layouts, and excavation plans. For structural or civil drawings, we may coordinate with other consultants as needed. 

Site plans, proposed building layouts, and any available site history are helpful. If not, don’t worry we can still assist and will guide you through the process.

Turnaround times vary based on project complexity, but we typically deliver geotechnical reports within 1 to 2 weeks after completing the field investigation. Expedited options may be available for time sensitive projects. 

We serve clients throughout the Lower Mainland, Fraser Valley, Sunshine Coast, and Vancouver Island. If your project is outside these areas, feel free to contact us to see how we can help.
