GEOTECHNICAL LABORATORY ENGINEERING SERVICES
SOIL TESTING SERVICES
Laboratory soil testing is important both to adequately characterize subsurface soils and bedrock to ensure the ground can withstand the load of your building or other infrastructure and to help you adjust your building plans accordingly. Proper geotechnical testing helps ensure you build on a solid foundation for a structure that lasts.
CONCRETE TESTING SERVICES
PRI Engineering’s Canadian Council of Independent Laboratories certified concrete testing laboratory performs compression testing and common field tests to help you meet your quality goals. When you receive your concrete testing report, you can use that information to ensure your concrete meets the quality and consistency you need for your project’s success.
AGGREGATE TESTING SERVICES
Variation in aggregate size, shape, strength, and durability has a big impact on quality and consistency. Our aggregate laboratory testing services help ensure your roads and structures meet your requirements with lasting, consistent quality.
T-TIME ANALYSIS
Our T-Time Analysis service is essential for septic system design, providing detailed assessments of soil absorption capacities to ensure optimal performance of septic systems. By combining laboratory testing with in-situ evaluations, we offer a comprehensive understanding of soil conditions, facilitating the design and implementation of effective and reliable septic solutions.
THERMAL RESISTIVITY TESTING
Our Thermal Resistivity Testing service offers precise analysis of soil and material properties to evaluate thermal conductivity, critical for ensuring the efficiency and safety of underground power cables and other buried utilities. Utilizing advanced methodologies and equipment, we deliver accurate data that supports optimal design and installation decisions in infrastructure projects.
ASPHALT MARSHALL AND SUPERPAVE ANALYSIS
Our in-house laboratory for completing Marshall and Superpave testing of asphalt provides critical analysis of asphalt mix performance, ensuring compliance with industry standards and optimal durability for roadways. These tests evaluate key properties such as stability, flow, air voids, and volumetrics, helping to predict long-term pavement performance under traffic and environmental conditions. This testing is essential for quality control in new asphalt mixes, pavement design verification, and troubleshooting issues like rutting or premature failure.
MEDIUM COMPLEXITY SOIL ANALYSIS
Our in-house laboratory delivers a comprehensive evaluation of soil behavior through a suite of standardized tests (low and medium complexity), including grain size distribution, Atterberg limits, moisture content, standard Proctor compaction, unconfined compression strength, and one-dimensional consolidation. This level of testing provides critical insight into soil strength, compressibility, and drainage—essential parameters for designing safe and durable structures.

Environmental Engineering
OVERVIEW
Our clients are our number one priority at PRI Engineering. We offer a range of environmental engineering services that minimize and manage your project risk and build sustainable operations. To each project, we bring knowledge of best practices and extensive experience across Canada and the U.S. to develop solutions that fit your project’s requirements.
ENVIRONMENTAL ENGINEERING SERVICES
GROUNDWATER AND DEWATERING
A dewatering management plan mitigates the risk of and cost of excessive water on-site during construction while minimizing the environmental impact of activities.
PHASE I AND PHASE II ENVIRONMENTAL SITE ASSESSMENTS
At PRI Engineering, our ESAs are designed to provide you with a detailed understanding of your site's environmental condition. Whether you’re a real estate developer, construction company, or involved in public sector projects, our ESAs are a crucial step in ensuring environmental integrity and compliance.
EXCESS SOIL MANAGEMENT
The team at PRI Engineering understands the regulations to help reduce your overall construction costs and mitigate potential environmental risk at the disposal level.
SOIL MANAGEMENT AND PLAN DEVELOPMENT
Our experienced team of professional engineers and technologists understand the challenges faced by our clients and can help you create a cost-effective and sustainable Soil Management Plan.
REMEDIATION
Our remediation services focus on assessing and mitigating soil and groundwater contamination to restore environmental quality and ensure regulatory compliance. We conduct detailed site investigations, develop tailored cleanup strategies, and implement solutions such as soil treatment, groundwater remediation, and risk management. This process is essential for managing spills, industrial site rehabilitation, and land redevelopment, protecting both human health and the environment.
RECORDS OF SITE CONDITION
Our Records of Site Condition (RSC) services document the environmental status of a property, providing critical data for land transactions, redevelopment, and regulatory approvals. We conduct thorough site assessments, including soil and groundwater testing, to confirm compliance with environmental standards and identify potential contamination risks. This process is essential for property owners, developers, and municipalities to ensure safe, compliant land use and mitigate liability concerns.
UNDERGROUND STORAGE TANK (UST) LOCATION AND REMOVAL
Our Underground Storage Tank (UST) location and removal services identify, assess, and safely remove buried fuel or chemical storage tanks to prevent soil and groundwater contamination. We use advanced detection methods and follow strict environmental regulations to manage UST decommissioning, ensuring proper disposal and site remediation if contamination is found. This service is essential for property owners, developers, and industries looking to eliminate environmental risks, comply with regulations, and prepare sites for redevelopment.
CONSTRUCTION INSPECTIONS
Quality is PRI Engineering’s priority. Our professional construction inspection services, and Quality Assurance/Quality Control monitoring put project owners and investors at ease. Our rigorous engineering standards and results-driven approach to problem solving helps de-risk project management, so that the project is completed in a timely manner and on budget.
Ensuring the construction proceeds according to the design specifications is as important as the detailed engineering process. Our experienced onsite inspectors verify design, supervise contractors, conduct non-destructive testing supervision, control documents and documentation, in addition to customized reporting.

OUR CONSTRUCTION INSPECTION SERVICES
SUBGRADE CONSTRUCTION INSPECTION
PRI Engineering’s subgrade inspection ensures that the best practices for subgrade preparation are followed to help increase the structural capacity of the soil.
SUBGRADE EVALUATION
PRI Engineering’s subgrade inspection ensures that the best practices for subgrade preparation are followed to help increase the structural capacity of the bearing soil. Our subgrade construction inspection services include comprehensive testing and analysis to ensure that your project meets industry standards and specifications.
STRUCTURAL CONFORMANCE
Structural Conformance is completed on a variety of civil construction projects to confirm adherence to a design, specification or code. Conformance is confirmed through site inspection and document review of materials, methodology and design requirements. Engineers play a significant role in the verification that as built conditions align with requirements ensuring conformance, safety and longevity of the finished product.
CONCRETE FIELD TESTING
At PRI Engineering we can complete the field testing to prepare your concrete samples for laboratory testing. [hyperlink field material testing section] Our materials testing technicians will perform concrete compression testing by applying compressive axial load until the samples fail. This determines the concrete’s strength. To help us do this, our well-equipped geotechnical laboratory includes a concrete grinder for preparation and a concrete compressive machine.
COMPACTION TESTING
Granular compaction testing is a crucial process in civil engineering and construction, ensuring the stability and durability of various structures built on granular soils. By subjecting granular materials to controlled compaction efforts, engineers can determine their optimal density and moisture content for a given application." for the description and then the rest for the learn more portion.
