Expertise
Expertise represents what we know how to do at a professional and technical level. These categories describe the core disciplines and problem domains—such as environmental remediation, groundwater control, ground improvement, foundations, marine services, and preconstruction support—that guide how projects are evaluated, designed, and executed.
What Makes Us Different
The Geo-Solutions Approach
Groundwater Control
Groundwater control refers to methods that address seepage, hydraulic pressure, and subsurface water movement that affect excavation safety and structural performance. Cutoff walls and deep drains are common solutions used to manage groundwater in complex site conditions.
Environmental Remediation
Environmental remediation refers to methods for isolating, stabilizing, and treating contaminated soil, sediment, and groundwater. In situ stabilization and solidification performed using soil mixing is a common environmental remediation approach.
Ground Improvement
Ground improvement refers to methods used to improve (often strengthen) weak, compressible, variable, or undesirable soils for specific performance enhancement. Soil mixing and rigid inclusions are common ground improvement solutions used to control settlement and improve subsurface behavior.
Foundations & Shoring
Foundations and shoring refer to systems used to support excavations and structures in difficult ground or groundwater conditions with elements that do not rely heavily on the soil. Auger cast piles are a common deep foundation technology and secant pile walls are a common earth retention technology.
Marine Services
Marine services refer to construction and remediation activities performed in rivers, harbors, and waterfront environments. In-water soil mixing performed from barges, dredging, and in-water capping are common marine construction approaches.
Preconstruction Services
Preconstruction services refer to early‑stage contractor involvement to address constructability components to inform project planning. Bench scale studies, constructability reviews, and pilot programs are commonly used to support design and solution selection.
