Secant pile walls are interlocking concrete-filled piles designed for deep excavations requiring high strength and impermeability. Tangent piles, with slight separations between each pile, are suited for less critical applications. We conduct detailed geotechnical investigations to select the optimal system, ensuring both structural integrity and cost-effectiveness.

Engineered from high-grade steel or composite materials, sheet pile walls are used in marine applications, embankments, and urban excavations. These walls provide vertical soil retention while minimizing lateral deflection. Our designs factor in soil-structure interaction and corrosion potential, using advanced modeling software to optimize wall thickness and driving depth.

Our design of soldier pile and lagging walls integrates steel H-piles driven (or drilled) into the ground at precise intervals, with timber or precast lagging placed between them. We analyze lateral earth pressures, structural load distribution, and material strength to ensure the system meets the demands of deep urban excavations.

We design sprayed concrete (shotcrete) for applications requiring flexibility and fast construction. Shotcrete is applied to stabilize soil or rock in tunnel portals, slopes, and retaining walls. Our expertise ensures that mix designs, spraying methods, and curing processes meet engineering standards for both temporary and permanent support.

To provide lateral stability for retaining systems under high loads, we design comprehensive tieback anchor systems as well as internal bracing elements like rakers and struts. Our designs accommodate both short-term and long-term load demands and incorporate corrosion protection measures to enhance the durability of the support system.

For underground projects, we specialize in the design of shaft structures and rock support systems, including rock bolts, shotcrete linings, and ring compression shafts. Our engineering solutions factor in rock mass classification, groundwater conditions, and tunnel geometry, ensuring stability throughout the excavation and operation phases.

These large precast modular blocks create gravity retaining walls that resist earth pressure through their own mass. We provide designs that optimize block size, layout, and reinforcement to meet the required loading conditions while ensuring a visually appealing structure.

These systems use soil reinforcement (typically geogrids or strips) to stabilize the retained soil mass. Our MSE wall designs are optimized for performance in high-load environments, including highways, bridges, and industrial sites. We integrate detailed geotechnical analysis to determine the appropriate reinforcement layout and material selection.

This type of retaining wall combines the principles of gravity walls and reinforced structures. We design these systems to handle substantial lateral loads by incorporating internal reinforcements within the wall structure. These walls are ideal for applications where space is limited, and high-strength retaining structures are necessary.

Micropiles are small-diameter, high-strength foundations ideal for constrained spaces and challenging soil conditions. Our design process begins with detailed geotechnical investigations to determine the most suitable pile diameter, length, and load capacity. We consider factors such as soil stratigraphy, groundwater levels, and structural loads to ensure the micropile system is tailored to meet project needs. Installation is carefully planned to minimize disruption, and we use advanced modeling techniques to predict pile behavior and ensure long-term performance.

Driven piles provide high-capacity foundation solutions for deep load transfer. Our team designs driven piles to meet the specific requirements of each site, considering factors such as soil conditions, pile material, and required load-bearing capacity. We perform detailed analyses to determine the optimal pile length and spacing, ensuring that the piles are driven to the correct depth to reach competent soil or bedrock. During installation, we monitor and adjust the process to optimize pile performance, avoiding potential hazards such as excessive vibrations.

Drilled shafts, or caissons, offer deep, large-diameter foundation solutions, especially in complex or variable soil conditions. We begin by assessing the geotechnical characteristics of the site, considering factors such as soil profiles and groundwater levels. Based on this data, we design drilled shafts with the appropriate diameter, length, and reinforcement to meet the structural loads. Our design includes considerations for lateral and vertical stability, as well as safety factors for excavation and concreting operations, ensuring that the shaft will perform optimally under expected loads.

Structural caissons provide a robust solution for heavy-load applications, particularly in marine environments. Our design process begins with an in-depth analysis of the environmental conditions and load requirements. We assess factors such as water depth, tidal influence, and soil properties to determine the appropriate caisson type and dimensions. We ensure that each caisson is designed to withstand harsh conditions, including hydrostatic pressures, corrosion, and long-term wear. During the design phase, we also consider constructability and environmental impact to ensure a cost-effective, sustainable solution.

Auger-cast piles are drilled into the ground and filled with reinforced concrete, providing a continuous foundation with minimal disturbance to surrounding soil. Our engineers select the optimal auger size and reinforcement layout based on detailed soil tests. The system’s design ensures high load capacity and reduced risk of settlement, and we utilize advanced modeling tools to assess the expected performance of the piles under various loading conditions. We also consider environmental factors, such as noise and vibration, ensuring that the installation process is both efficient and environmentally friendly.

Each project presents unique challenges, and at Reliance Engineers, we take a custom approach to every deep foundation system. We begin with a comprehensive geotechnical analysis and collaborate with clients to develop tailored designs that account for specific soil conditions, structural loads, and environmental factors. Our team uses cutting-edge software and advanced modeling techniques to ensure optimal performance and long-term stability. From conceptual design to final implementation, we deliver cost-effective, efficient, and reliable deep foundation solutions that exceed expectations.
