Services
Dam Engineering
Our dam engineering services focus on remediation, stability analysis, and construction monitoring for hydroelectric, flood control, and water supply infrastructure. We address challenges like seepage, erosion, and structural integrity through tailored solutions. With expertise in both new construction and rehabilitation, we ensure compliance with safety standards while extending asset lifespan for public and private clients.
Foundation Design
We provide comprehensive foundation design services including subsurface exploration, load-bearing analysis, and construction recommendations. Our approach integrates geotechnical data to optimize shallow and deep foundation systems for commercial, industrial, and infrastructure projects. By addressing soil-structure interaction challenges, we ensure structural stability and long-term performance across diverse subsurface conditions.
Slope Stabilization
Our slope stabilization expertise addresses rockfall mitigation, landslide remediation, and embankment reinforcement. Using techniques like soil nailing, grouting, and drainage control, we enhance geotechnical stability for transportation corridors, residential areas, and industrial sites. We conduct detailed failure analysis and implement permanent solutions to mitigate risks from unstable soil and rock formations.
Environmental Remediation
We specialize in remediation of petroleum-contaminated sites, hazardous waste containment, and groundwater protection. Our services include site assessment, risk evaluation, and design of containment systems like slurry walls and soil vapor extraction. We collaborate with regulatory agencies to develop cost-effective solutions that meet environmental compliance requirements while minimizing ecological impact.
Excavation Shoring
Our excavation shoring designs ensure safe and stable temporary support for deep excavations in urban and challenging geotechnical environments. We employ methods like soldier pile walls, sheet piling, and hydraulic shoring systems tailored to soil conditions and project constraints. These solutions enable safe construction of foundations, utility installations, and infrastructure projects while protecting adjacent structures.
