Drilled Caissons up to 54”

Large-diameter cylindrical shafts drilled into the ground and filled with concrete to provide foundational support for bridges, buildings, or other structures, offering stability and load-bearing capacity.

Drilled caissons, also known as drilled shafts or drilled piers, are large-diameter cylindrical excavations drilled into the ground and filled with concrete to provide foundational support for bridges, buildings, or other structures. They are used in areas with high loads or challenging soil conditions, offering stability, durability, and resistance to lateral and uplift forces.

Additional Areas of Expertise

Secant Walls

Constructed by overlapping concrete or grout-filled piles to create a continuous wall, offering structural support and groundwater containment for underground structures or excavations.

Soil Nail Walls

Constructed by installing steel rods (nails) into the soil and grouting them to create a reinforced earth structure, providing stability for excavations, slopes, or retaining walls.

Grouting

Injection of grout into the ground to improve soil stability, fill voids, or seal fractures, offering reinforcement and waterproofing for various construction applications.

Rock Anchors

Installed in rock formations to provide stability and support for slopes, retaining walls, or other structures, preventing soil erosion and enhancing safety.

Low Vibration Applications

Techniques and equipment designed to minimize ground vibrations during construction activities, reducing potential damage to nearby structures or disturbances to the environment.

Noise Wall Foundations

Foundations designed to support noise barriers or sound walls along highways or railways, reducing noise pollution and enhancing community comfort.

Marine Bulkheads

Structures built along shorelines or waterfronts to prevent erosion, manage water levels, or facilitate maritime activities, providing stability and protection against waves or currents.

Drilled Shafts up to 72”

Deep cylindrical excavations drilled into the ground and filled with concrete to support structures in challenging soil or geological conditions, offering versatility and reliability in foundation construction.

Drilled Caissons up to 54”

Large-diameter cylindrical shafts drilled into the ground and filled with concrete to provide foundational support for bridges, buildings, or other structures, offering stability and load-bearing capacity.

Driven H Piles

Steel piles driven into the ground to support structures or transfer loads to deeper soil or rock layers, offering high load-bearing capacity and durability.

Tie-backs

Structural anchors installed to provide lateral support for retaining walls or excavation shoring systems, enhancing stability and preventing soil movement.

Underpinning

Method of reinforcing or stabilizing existing foundations by extending or strengthening them, typically used to prevent settlement or structural damage in buildings or infrastructure.

Timber Piles

Wooden piles driven into the ground to support structures, particularly in marine environments or areas with soft soil, offering a cost-effective and environmentally friendly foundation solution.

MTBM (Microtunnel Boring Machine)

Utilizes advanced machinery to create precise tunnels with minimal surface disruption, ideal for installing pipelines, conduits, or cables beneath obstacles like roads, rivers, or buildings.

Slurry Walls

Constructed by excavating a trench and filling it with a slurry mixture to support the surrounding soil, providing structural integrity and preventing water infiltration, commonly used in environmental remediation or underground construction.

Deep Soil Mixing

Technique involving mechanical blending of soil with cementitious materials to improve its strength, stability, and load-bearing capacity, often used for foundation reinforcement or soil stabilization.

Mini/Micropiles

Small-diameter piles drilled and filled with grout or concrete to support structures in areas with limited access or challenging soil conditions, offering versatility and efficiency in construction projects.

Drilled CFA Piles

Continuous Flight Auger (CFA) piles are installed by drilling into the ground with a rotating auger, then filling the hole with concrete, providing load-bearing support for structures like buildings or bridges.

Steel Sheet Piling

Installation of interlocking steel sheets to provide temporary or permanent support for excavations, seawalls, or waterfront structures, offering stability and erosion control.

Shaft Construction

Construction of vertical or inclined shafts to provide access to underground facilities, such as mines, tunnels, or utility networks, using specialized techniques and equipment for safety and efficiency.

Products Pipe Pressure Testing

Testing the integrity and durability of installed pipes through pressurized water or air, ensuring they meet industry standards and can withstand operational conditions.

Horizontal Directional Drilling (HDD)

Allows for the installation of underground utilities along a predetermined path with minimal surface disruption, making it suitable for crossing obstacles like rivers, highways, or densely populated areas.

Jack and Bore

Non-disruptive method for installing underground utilities by pushing pipes through pre-drilled holes, avoiding surface disturbance and minimizing environmental impact.

Annular Pressure Grouting

Technique for strengthening and sealing the surrounding soil or rock formations during tunneling or boring operations, enhancing stability and preventing water infiltration.

Conventional Tunneling

Traditional method involving excavation and support systems to create tunnels, suitable for various underground constructions such as transportation passages or utility conduits.
