Foundations & Earth Retention

Deep foundations are structural elements that transfer loads from a building or structure to deeper, more competent soil or rock layers when the shallow soil near the surface cannot support the load adequately. Several deep foundation types are designed to cater to specific soil conditions and structural requirements. Pile foundations are one of the primary deep foundation types. These are installed by driving piles into the ground using impact hammers, vibratory hammers, or hydraulic presses. Common materials for driven piles include concrete, steel, and wood. Bored piles are another type created by drilling holes into the ground and then filling them with reinforcement and concrete or grout.

Pier foundations consist of individual piers that support the load of a structure and are often used in bridge construction or elevated structures. Cofferdams are temporary structures built to create a dry work environment for constructing foundations in bodies of water. Sheet piles are thin, interlocking sheets of steel, vinyl, or wood driven into the ground to create continuous barriers to retain the earth. Diaphragm walls are constructed by excavating a trench, filling it with concrete, and reinforcing steel to create a continuous vertical wall. Caisson foundations are large, watertight chambers sunk into the ground and filled with concrete or other materials, often used in bridge piers and underwater structures.

Walbec’s Zenith Tech (ZTI) team provides various earth retention solutions to support excavation, including sheet piling, trench box, soldier piles, and lagging. We provide fully engineered solutions from our in-house licensed Structural Engineers, and our master operators and skilled tradesmen are equipped with state-of-the-art equipment to handle the construction of all types.

Choosing the most appropriate deep foundation type depends on factors such as soil conditions, magnitude of loads, site access, and project requirements. Each type of deep foundation has advantages and limitations, and engineers select the most appropriate type based on carefully considering these factors. The ZTI team can help you determine your project's best deep foundation type and provide expert installation services. Our team's knowledge and professionalism ensure we design, engineer, manage, and effectively implement your vision while delivering the highest quality results.

• Driven Piles: These piles are installed by driving them into the ground using impact hammers, vibratory hammers, or even hydraulic presses. Common materials for driven piles include concrete, steel, and wood.
• Bored Piles (Drilled Piles): These piles are created by drilling holes into the ground and then filling them with reinforcement and concrete or grout. They are suitable for various soil conditions and can be used for deep foundation needs.

Our private industry partners value the collaborative relationship Zenith Tech cultivates by implementing a proven process to ensure success. Our clients rely on our knowledge and professionalism to safely and effectively design, manage, and implement their vision.
