We offer a full range of geotechnical solutions for projects big and small.
One solution does not fit all—we have a deep toolkit of techniques and custom applications for every type of project.
Carry loads deep underground or behind an earth retention wall. Anchors are used to support walls against lateral earth and water pressures in earth retaining structures, to secure landslides, tunnels, shafts, dams and deep excavations.
A cast-in-place deep foundation solution that uses a hollow stem continuous flight auger. Augercast piles are cost effective alternative to other deep foundation systems. They cause minimal disturbance and vibrations and are suited for low noise and/or environmentally sensitive areas.
Load-bearing elements that are excavated rectangular piles used as foundations to resist large vertical and support significant horizontal loads. Barrettes can accompany the construction of diaphragm walls because they utilize the same equipment.
Chemical grouting is a technique used to fill small cracks and voids found in rocks as well as to solidify granular soils en masse by injecting a flowable solution or grout between the soil particles.
A very stiff homogeneous low slump, low mobility grout mix is injected under relatively high-pressures and at low injection rates to subsurface locations in pre-designed patterns in order to displace and compact loose soils.
Used to create temporary or permanent deep foundations and earth retention walls for deep basements, shafts, parking garages, marine structures, dams and permanent cutoff walls.
Used to support structures with large axial and lateral loads by excavating cylindrical shafts into the ground and filling them with reinforced concrete. Drilled shafts are an economic solution that can be installed in a variety of different ground conditions.
The process of breaking up the soil with a high-pressure jet in a predrilled borehole and mixing the loosened soil with a cement grout. Nicholson’s jet grouting method is suitable for a large variety of soil conditions.
High-capacity drilled deep foundation elements typically between 5–12 inches in diameter that can extend to depths of over 200 feet and achieve working loads of over 200 tons. Micropiles are comprised of high-strength steel casing, rebar and grout.
Introduces cement or chemical-based grout into soil pores without significantly changing the original soil volume and structure, improving the strength and bearing capacity of granular soils without disturbing them.
Improves the ground's strength or reduces permeability using injections of specially formulated cement based mixes. Rock grouting can be used to decrease water flow through fractured rock, plus it can be performed in areas with space constraints.
The drilling or augering of a series of overlapping concrete piles reinforced with steel beams or rebar to form a wall. Secant pile walls can be successfully installed in virtually any ground conditions, including grounds that are typically difficult to work with.
Breaks up the soil in situ and mixes it with a cement/bentonite grout in place to create a strong homogenous and impermeable, reinforced mass. Soil mixing can be used to create walls and plugs and for mass treatment and ground improvement.
Used for stabilizing slopes and landslides, limiting ground settlement and providing earth retention systems for deep excavations.
