Drilled Piers

DRILLED PIERs: A versatile solution for constructing strong foundations

When it comes to foundation installation, repair and replacement, there are a number of options for completing projects. Drilled piers are a common approach. Sometimes called caissons, drilled piers are the perfect foundation solution for structures with heavy lateral and axial loads.

How are Drilled Piers Installed?

Drilled piers are a deep foundation system that uses large concrete cylinders to spread a structure’s load down through the surrounding ground. To install a drilled pier, we start by augering and cleaning a hole of the right depth and diameter for your project. Boulders discovered along the way need to be removed or drilled through because they can affect the pier’s strength. Depending on the project, a permanent or temporary casing may be inserted into the hole at this point. Once a hole is drilled, a rebar cage is placed inside to offer reinforcement. With the cage in place, the concrete can be poured. . Once that’s completed, we can remove temporary casings. Because much of the work of installing a drilled pier happens underground, they can be installed in a variety of conditions, including sites with low headroom or limited access. In fact, drilled piers are often the preferred approach for projects based on difficult or unsteady soil, or for locations with a high water table.

What Projects Call for Drilled Piers?

An engineer will recommend using drilled piers for a number of concrete projects because of their strength and versatility. Drilled piers can support a wide range of structures and be used in a number of applications, including:

  • Buildings
  • Retaining Walls
  • Tanks
  • Bridges
  • Towers
  • Foundation Repairs

Because the process of drilling the hole and pouring the support is fairly quiet, drilled piers are an excellent choice when local conditions are a consideration. Drilled piers can also be used in a wide range of soil types.
