Deep Foundation Works

DAT Foundations General Contracting LLC – OPC specializes in providing comprehensive deep foundation solutions to support structures in challenging soil conditions and ensure structural stability. Our expertise in deep foundation techniques, including cased piling, CFA (Continuous Flight Auger) piling, and micro piling, combined with advanced equipment and skilled personnel, enables us to deliver efficient, cost-effective, and reliable foundation solutions. Here’s a detailed overview of our deep foundation capabilities:

Cased Piling

Cased piling, also known as drilled casing piles or casing oscillator piles, is a deep foundation technique used to construct large-diameter piles in difficult soil and groundwater conditions. DAT Foundations utilizes specialized equipment and casing systems to drill boreholes, install steel casings, and fill them with concrete or grout to form structural piles. Cased piling provides high load-bearing capacity,  making it suitable for various applications such as bridges, high-rise buildings, and industrial facilities.

CFA Piling

CFA piling is a versatile deep foundation technique that combines drilling and concrete placement in a continuous process. DAT Foundations utilizes CFA rigs equipped with augers to drill into the ground while simultaneously injecting concrete through the hollow stem of the auger. As the auger is withdrawn, it leaves behind a concrete pile with high axial capacity and minimal soil disturbance. CFA piling is ideal for soft to medium soil conditions and can accommodate various pile diameters and lengths, making it suitable for a wide range of foundation applications, including buildings, bridges, and infrastructure projects.

Micro Piling

Micro piling, also known as mini piles or pin piles, is a specialized deep foundation technique used in restricted access and low headroom environments or areas with difficult soil conditions. DAT Foundations employs small-diameter steel or concrete piles, typically ranging from 100mm to 300mm in diameter, to provide support for structures where conventional piling methods are impractical. Micro piles are installed using hydraulic rigs and are often reinforced with steel reinforcement or grouted to enhance load-bearing capacity.
