CDI Services
CDI specializes in delivering advanced pile-driving services, supporting a wide range of structural foundations for commercial, industrial, and infrastructure projects. With expertise in driving steel H piles, steel pipe piles, concrete piles, and timber piles, CDI leverages its experience and diverse equipment to ensure safe, precise, and stable installations in even the most challenging environments.
Construction Drilling offers extensive design services for deep-foundation, heavy civil and general construction. We can provide value-added engineering for your foundation and earth retention requirements at the concept stage of your project. In many instances, a single drilled shaft can replace a cluster of piles, eliminating the need for (and cost of) a pile cap.
Construction Drilling has an extensive background in marine construction and in supplying marine contractors with drilling equipment. We have successfully installed drilled piles and rock-socketed drilled piles along the Pacific Coast from San Francisco to Alaska, and also on the Atlantic Coast. We also install drilled shafts in fresh water, and have done so over rivers, in hydroelectric dams and on lakes.
Construction Drilling has the experience to place reinforcing steel and concrete for piling and drilled shafts on your project. We can provide custom-engineered lift and placement plans that are specific to your needs. We have successfully tremie-poured thousands of drilled shafts and piles in all conditions including artesian.
We can also provide various grouting services such as consolidation and annular grouting. In certain geological formations pre-stabilization grouting is required to bind the formation together.
Construction Drilling owns many types of temporary work platforms and over 300’ of temporary work bridges, with access to an additional 300’.
CDI provides comprehensive solutions for earth retention and excavation support through the installation of shoring walls, cofferdams, and cutoff walls. We offer various types, including secant pile walls, soldier pile walls, sheet pile walls, O-pile walls, and passive walls. These systems are essential for stabilizing excavation sites, preventing soil movement, and ensuring the safety of surrounding structures. Our expertise in these methods ensures that your project remains secure and stable throughout its duration.
CDI specializes in the installation of drilled shafts, which are critical for the foundations of buildings, bridges, and industrial installations. Utilizing advanced techniques such as down hole hammers, rotary bits, and reverse circulation, CDI can handle various ground conditions, from hard rock to soil. Our drilled shafts provide stability and load-bearing capacity, ensuring the structural integrity of your project. Whether for commercial or industrial applications, our expertise in drilled shafts guarantees precise and reliable foundation solutions.
