Types of Drilled Piers Used in North Texas

When it comes to foundation repair, a variety of solutions are available in the Dallas-Fort Worth area. No one solution is better than another; it comes down to what is best for a particular building type and the soil condition it rests on. Usually, this includes some form of pier. We’ll go over the three main types of piers and how they work as a foundation reinforcement.

1. Concrete Piers

This is the most common pier type with a wide range of applications due to their durable reliability and affordability. This is also known as “pressed concrete piers” or simply “pressed piers.” Installers use a hydraulic press to drive the concrete cylinder into the ground. For additional stability and load-bearing capacity, the concrete caps are reinforced with steel plates.

2. Drilled Piers

Drilled concrete piers are quite versatile. This is because the piers do not rely on the weight of the structure to press them down and keep them stable. This makes it a popular solution for pier and beam and slab foundations.

With drilled piers, a hole is dug using an auger. A rebar is installed in the hole and is filled with heavy-duty concrete. Despite the durability of drilled piers, the use of an auger does create a more invasive installment process. This includes heavier noise traffic and possible foundation disruption in adjacent areas.

3. Steel Piers

Steel piers offer even more durability than concrete piers and are usually recommended as support for extremely heavy structures, such as public multi-story facilities. Some steel piers are installed outside the foundation perimeter using hydraulic rams and a bracket that transfers the weight of the structure to the piers. Other steel piers are installed right under the perimeter grade beam.

The piers consist of hollow steel pipes that can be filled with cement and grout to protect against rust and upheaval. Like concrete piers, steel piers may also be reinforced with steel cables.
