There’s different types of concrete piers. There’s the true drilled shaft concrete pier with concrete poured into it. These piers are drilled down to refusal, 15, 20 feet deep. Concrete’s poured in. Rebar’s put in. Then the house is jacked up off of those piers.
The most common nowadays are steel piers. It’s a lot less invasive. A lot quicker, where we put the steel brackets under the foundations, and then we hydraulically push the pipe in the ground.
There’s the concrete segmented type piers. Which, some people use nowadays, are not really the best type of application for our part of the country because the clay soil is you cannot push the concrete deep enough.
