The process of restoration for equalization of residential concrete foundations usually includes the basics of plate with piers or concrete or steel. Just as there are two basic types of concrete piers, drilled or bell bottom, and secondly, pressed the berths, which use ready-made sections, you will also find a couple of variations of steel pier.

There are generally two types of steel piers used to support a concrete slab foundation. They are the resistance and screw. Both have their advantages and best use.

Resistance piers hydraulically shoved or driven straight down through the soil using the weight of the structure as opposed to. Berths are pushed to the bottom reaches the soil it is difficult to maintain the building.

Resistance piers are best suited for structures that must be raised, or have very high demands on load. Common usage would be to maintain and raise the foundation of a house.

Spiral piers hydraulically turned or twisted in the soil much like a corkscrew. Berths may contain one or more “flights” that pull the pier into the soil. These piers are screwed down until they reach the soil that is heavy and thick enough to maintain the desired result. Since they’re twisted, they can not be pushed or pulled. They can be used either to support the fund, or save the structure from coming out of the soil. Examples include retaining walls and houses built on the hillside. These types of supports are also used during the pre-construction in order to prevent further failure reason.

Both resistance and screw bearings are made in various configurations to support different types of structures. Selecting the proper calculation of the pier is an important independent engineer and the contractor should make reference to the work.

As a homeowner you may be given to select the type of supports offered by an engineer or contractor to repair your foundation. Now you have a better understanding of two basic types of bearings and steel it uses.
