Which foundation pier is best in Houston?
There is no single best pier. Pressed pilings are common and cost-effective; drilled piers and steel piers are often chosen for deeper support or heavier loads. An engineer can specify the right system.
Pressed Pilings vs. Drilled Piers vs. Steel Piers
Most slab repairs in the Houston area use one of three pier types. Here is how they differ and why a specialist might recommend one over another.

Why piers are used
Piers transfer the weight of a house past the most active clay near the surface to firmer soil deeper down. Once piers are set, the foundation can be lifted and supported on them. The right pier depends on soil, load, access, and the engineer's or specialist's findings.
Pressed concrete pilings
Short pre-cast concrete cylinders are stacked and pushed into the ground with a hydraulic jack, using the weight of the house for resistance, until they stop moving (refusal). A cap is set and the slab is shimmed.
- Pros: widely used in Houston, relatively fast, typically less expensive, less excavation.
- Cons: depth is limited by how much the house weighs; segments may not be connected unless a cable or rebar is used.
Drilled concrete piers (including bell-bottom piers)
A hole is drilled to a specified depth, often with a wider “bell” at the bottom, reinforced with steel, and filled with concrete. The slab is then lifted onto the new piers.
- Pros: depth and size can be engineered, strong for heavy loads, commonly specified by engineers.
- Cons: more excavation, concrete needs time to cure, usually higher cost.
Steel piers
Steel pipe sections are pressed or driven to deeper, load-bearing soil, sometimes much deeper than concrete pilings.
- Pros: can reach greater depths, quick to install, connected sections.
- Cons: cost, and corrosion protection matters in wet soils.
Questions to ask about any pier plan
- How deep will the piers go, and how is depth verified?
- How many piers, and where? Can I see a pier layout drawing?
- Does an engineer design or approve the plan?
- What does the warranty cover, and is it transferable?

Frequently asked questions
How deep do foundation piers go?
It varies. Pressed pilings go until refusal, drilled piers go to an engineered depth, and steel piers can go deeper to reach load-bearing soil.
How many piers does a house need?
It depends on the size of the home and the area that has moved. A written layout from an evaluation shows exact counts and locations.
