Concrete Drilled Piers

Drilled Piers, or Concrete Drilled Piers, are systems of foundation repair that involve drilling a 8 inch or 12 inch diameter pier to a depth of 10 to 15 feet deep. This is accomplished using an auger or a bobcat. Once the hole is dug, rebar is placed in the hole and then filled with 3,500 psi cement mixture. The cement then has to cure for 7–10 days. After the cement has cured, the leveling process can be done. Leveling is accomplished using the same method as Pressed Concrete Piles and Steel Piers.

Drilled piers have been used in the Dallas area for over 40 years, and can be an effective method of repair. Most structural engineers approve of this foundation repair method.

Advantages and Disadvantages

The advantages of a Drilled Pier is that it does not use the weight of the structure to install the pier. This is important for lighter structures such as older frame constructed homes that are not heavy enough for pressed piles or steel piers to be installed to proper depths.

The disadvantage is that because of the cement curing time, most jobs will take at least 10 days to complete.
