Geo-Solutions, Inc (Geo-Solutions, GSI) helps contractors, owners and engineers select and implement cost-effective and practical construction solutions to environmental and civil engineering problems involving soil and groundwater. Geo-Solutions specializes in the construction of slurry trench cutoff walls, soil mixing, and jet grouting.
Geomechanica develops simulation software and provides consulting and laboratory testing services for rock engineering applications. These applications include hydraulic fracturing, assessment of excavation damaged zone around underground openings, rock slope and dam stability, and block caving.
Geomechanica's engineering simulations are based on an advanced finite-discrete element method (FDEM), known as Irazu. Irazu is a numerical code which combines principles of continuum mechanics with discrete element algorithms to simulate multiple interacting deformable and fracturing bodies. A unique feature of this technique is its capability to capture the transition of a solid from a continuous to a discontinuous state by directly simulating fracturing and fragmentation processes.
Besides simulations software and simulation-aided consulting services, Geomechanica offers standard rock mechanics laboratory testing services. Based in the Greater Toronto Area (Ontario, Canada), these testing services include: uniaxial and triaxial compression test, Brazilian disc tensile test, direct shear test, Cerchar abrasivity test, Slake durability test, and point load test, to name a few.
