Key takeaways
- Helical piers are screwed in, push piers are pushed down and slab piers support interior floors.
- The right choice depends on soil, structure weight and access.
- A good plan uses measurements, not a one-size-fits-all system.
Helical piers
A helical pier is a steel shaft with screw blades that is rotated into the ground. The torque used to install it tells the crew how well the soil is carrying the load. They install quietly with small equipment and can be loaded right away.
They suit lighter structures, soft soils and tight access.
Push piers
Push piers are steel tubes driven section by section using the weight of the structure as resistance. They are driven until they reach a firm layer, so the house cannot settle past that depth.
They suit heavier homes where a firm layer or rock is within reach.
Slab piers
Interior slab piers support a settled slab foundation from below, often with a small pit and a bracket. Combined with foam or leveling they restore floors from inside.
A full repair may mix methods around the perimeter and under the slab.

Quick answers
Which pier type is best?
There is no single best. Soil, load, access and the foundation type decide, and an inspection tells which fits.
How many piers will I need?
They are usually spaced every six to eight feet along affected footings, and the count depends on the loads and the movement.
