Geo Canada Rex is dedicated to providing a wide range of specialized services to construction companies, ensuring the success of their projects through precise and reliable geotechnical, geophysical, and geological solutions. Our team of experts employs state-of-the-art technology and methodologies to deliver exceptional results. Below is a detailed overview of the services we offer:

Geotechnical Surveys

• Site Investigation: We conduct comprehensive analyses of soil and rock conditions through drilling, sampling, and testing. This is essential for understanding subsurface conditions and involves drilling boreholes, collecting soil and rock samples, and conducting in-situ tests such as Standard Penetration Tests (SPT) and Cone Penetration Tests (CPT). Results inform foundation design and identify potential issues such as soil instability, high groundwater levels, and contamination.
• Soil Testing: Laboratory testing of soil samples determines their physical and mechanical properties, such as grain size distribution, moisture content, density, shear strength, and compressibility. These parameters are crucial for designing foundations, retaining walls, and other structural elements.
• Rock Testing: Laboratory testing of rock samples assesses their strength and durability through tests such as uniaxial compressive strength, triaxial tests, and slake durability tests. This information is necessary for designing structures in or on rock formations.

Geophysical Surveys

• Ground Penetrating Radar (GPR): This non-invasive method uses radar pulses to image the subsurface, detecting buried utilities, voids, and changes in material properties. GPR provides high-resolution data, making it ideal for urban construction sites.
• Electrical Resistivity Tomography (ERT): ERT measures subsurface resistivity distribution to identify variations in soil and rock properties, such as moisture content and contamination. It is useful for site characterization, locating groundwater, and assessing contamination.
• Seismic Refraction: This method analyzes the travel times of seismic waves through the subsurface to map subsurface layers and determine material properties such as density and elasticity. It is particularly useful for identifying bedrock depth and quality, and assessing rippability.

Foundation Engineering

• Foundation Design: Based on site investigation data, we design suitable foundations such as shallow footings, deep piles, or raft foundations. This involves considering load-bearing capacity, settlement, and soil-structure interaction to ensure stability and safety.

Ground Improvement

• Soil Stabilization: Techniques such as chemical grouting, compaction, and reinforcement improve soil properties, enhancing load-bearing capacity and reducing settlement of weak or loose soils. Methods include the use of cement, lime, or other additives, mechanical compaction, and the installation of geosynthetics.
• Vibro-Compaction: This method uses vibratory probes to densify granular soils, increasing their density and shear strength, reducing the risk of liquefaction, and improving foundation performance. It is suitable for large-scale projects such as industrial facilities and port structures.

Construction Monitoring

• Geotechnical Instrumentation and Monitoring: We install and monitor instruments to measure ground movement, stress, and other parameters, providing real-time data on the behavior of soil and structures during construction. This helps in managing risks and ensuring safety.
• Structural Health Monitoring (SHM): Continuous monitoring of structural integrity using sensors and data acquisition systems detects structural changes and potential failures in real-time, allowing for timely maintenance and repair, critical for ensuring the longevity and safety of bridges, buildings, and other infrastructures.

Geospatial Services

• Topographic Surveying: Using GPS, total stations, and drones, we provide detailed mapping of land surface features. This is essential for grading, drainage design, and infrastructure layout, providing accurate elevation data and maps for site planning, design, and construction.
• Geographic Information Systems (GIS): Our GIS services manage and analyze spatial data to support construction planning and decision-making. This integrates various datasets, including topography, utilities, and environmental data, into a single platform, enhancing project planning, resource management, and environmental monitoring.

Geotechnical Consulting

• Geotechnical Risk Assessment: We evaluate the potential geotechnical risks associated with construction projects, identifying risks such as landslides, soil erosion, and settlement, and providing recommendations for risk mitigation to ensure project safety and stability.
• Slope Stability Analysis: Using computational models and field data, we evaluate the stability of natural and artificial slopes, determining the potential for slope failure and providing design recommendations for slope reinforcement and stabilization. This is critical for projects involving embankments, cuttings, and retaining structures.

Remote Sensing and Imaging

• LiDAR (Light Detection and Ranging): Our LiDAR services use laser scanning to create high-resolution topographic maps, providing precise 3D models of terrain. This is essential for site planning and infrastructure design, helping identify terrain features, vegetation cover, and potential hazards.
• Thermal Imaging: We capture infrared images to detect heat variations in structures, identifying issues such as thermal leaks, insulation defects, and moisture ingress. This is useful for building inspections and energy efficiency assessments.

Training and Capacity Building

• Technical Training Programs: We offer courses on geotechnical engineering, geophysics, and related disciplines to enhance the skills and knowledge of construction professionals. This includes hands-on training, workshops, and seminars.
• Workshops and Seminars: Our sessions share knowledge and best practices in geotechnical and geophysical engineering, promoting continuous learning and professional development, fostering innovation, and improving operational efficiency in construction projects.
