Foundation fix Methods

Because each home and basal soil health can be different, there is no easy respond that applies to all concrete foundation heal situations. Each case needs to be examined individually by an independent structural engineer or professional foundation heal contractor.

Some contractors will have biases to one formula over an additional one because they only perform one type of service.

Leveling or underpinning a concrete foundation is performed using piers. The piers are used to contribute reserve for an area of the foundation that needs to be raised. The four main types of piers used in underpinning are drilled concrete piers, concrete pressed pilings, steel piers and helical piers. The type of soil under your home and the type of foundation determines which pier should be used. As always, use only as directed.

Here is a quick summary of the most coarse foundation heal techniques:

Resistance or push piers often have the best lifting possible for foundation repair. This is because these types of piers are "pushed" or "rammed" down into the ground, through the inadequate soil until they hit a hard surface or load bearing stratum. The weight of the buildings is used as a counter-force to hydraulically push these piers into the ground. Once they hit this bottom, they can be pushed even added so that they really lift the buildings back to their original level. The advantage of this type of pier is that a soils article is not really important to know how deep the piers must be pushed. It becomes self-evident. Once the "bottom" is reached the buildings can be lifted. These types of piers are typically used for heavier structures but are also excellent for singular story residential homes.

Helical piers are most often used to reserve a concrete slab but not lift it. These types of piers are twisted into the ground much like a corkscrew. Each pier has one or more "flights" that are like blades that do the pulling into the ground. These flights keep the pier in place after installation. The advantage of a helical pier is that is can be used on very light structures like a porch. However, to install a helical pier properly, a soils test should be performed by a geotechnical engineer to resolve how far down the soil is sturdy sufficient to reserve the structure. After all, if you turn a helical into loose soil, it loses most of its holding power and who wants a flaccid pier?

Helical piers are very beneficial in other applications such as tie-backs. Since they are screwed into the ground, and held in place with their flights, not only can they reserve downward pressure, but then can reserve an equal estimate of outward force. They can hold things like retaining walls into the ground. Helical piers can be used in pre-construction situations. They are installed before the foundation is located to prevent any hereafter foundation settlement. Also, helical piers can be used in conjunction with resistance piers on hillside homes to lift the buildings and keep it in place.

Both resistance and helical piers are made in a variety of configurations to reserve a variety of structures. The selection of the permissible pier is an important calculation the foundation heal undertaker of a package deal must make prior to quoting a job. There are steel pilings, and concrete pilings held together with steel cable or rebar. Pressed pilings can be held together with steel and concrete or just weight and friction. Weight and friction also describes one of my sister-in-laws.

The bell bottom or "drilled" pier method uses freshly poured concrete on-site that forms a bell shaped foot in load bearing soil and is reinforced with rebar. The depth, size and location of the shafts can be institution designed for your house. The bell bottoms are private pretty far private so your neighbors can't see them and make fun of you.
