Deep Foundations
Beaty Construction designs, installs and tests a wide range of deep foundations.
Drilled Shafts
Drilled shafts or caissons consist of concrete and reinforcing steel. This is typically the solution when high axial and/or lateral capacity or a rock socket are required for a foundation system. Beaty has drilled shafts up to 108” diameter and can handle difficult soil conditions requiring cased shafts or slurry drilling. Beaty’s drilling equipment fleet also offers the ability to drilled shafts with limited access and low headroom.
Driven Piling
Driven piles are the most common and generally most cost-effective type of deep foundation. Beaty Construction installs driven steel structural shapes (W and HP shapes) and shell or pipe piles, as well as timber piling. These types of piles are generally installed using crane mounted impact or vibratory hammers.
Augered Cast-in-Place Piles
Augered Cast-in-Place piles – also simply known as “augercast” piles – are concrete piles that are installed by drilling into the soil using a continuous auger with a hollow stem. When the auger reached the desired tip elevation, the tool is withdrawn as structural grout is pumped through the hollow stem. This method of construction permits concrete piles to be installed in soft, loose and wet soils without having to use casings – or producing large vibrations.
Helical Piers
Helical piers are steel elements consisting of solid or hollow posts with one or more levels of helical flights attached to the tip. This type of foundation is drilled in to the required depth, adding additional post sections as required. Since helical piers are entirely made of steel, they may be placed into service immediately. Unlike driven piles, the installation method does not produce large vibrations.
Micropiles
Micropiles are a specialty drilled-in foundation element generally used in very challenging situations requiring placement in limited space or unusual geometries. These elements are typically used to augment or replace the capacity of existing foundations.
Ground Improvements
Ground Improvements, including stone columns and rigid inclusions, are a lower cost solution for increasing soil bearing pressures for foundation systems, building floor slabs, or other applications where bearing pressures of native soils do not meet project needs. Beaty Construction offers a design-build ground improvement system using various techniques designed to match the characteristics of the soil and the design needs of the structures to be supported.
