What is a helical pier foundation?
Installing helical piers by hand is not overly simple and should be done by a professional. Helical pier installers in Springfield, MO have made a list of installation steps and techniques:
- Holes are to be dug at all of the helical placement points, this way you can actually access the foundation. Generally, this is to be done from the outside of the structure but can be done on the inside.
- If necessary, concrete on the foundation will be chipped away to make sure the proper transfer of the loads to the piers.
- The piers are driven to an embedment or torque as specified by a trained professional, or to final torque refusal or until you find the bedrock. Pier depth will not be the same for every project but depends on the soil.
- Brackets are to be attached to the foundation and pier to allow lifting.
- Holes are the re-compacted and the area where the job took place should be cleaned up
Are helical piers good?
A lot of the best structural engineers in the area have given their stamp of approval to the use of helical piers. They are a modern and innovative solution to foundation damage occurring in a home. Helical piers are a popular repair method that differ from push piers in a variety of ways. The steel tubes are first fitted with helical plates, this make them have the appearance of a giant screw. These plates act to pull, rather than push, the pier deep into the ground. The next step consists of these piers being hydraulically drilled into the ground until they reach competent soil, helical piers are turned until they reach the proper depth. Lastly, these steel brackets that connect to the piers, are to be secured at the end of the instalment instead of the beginning. Helical pier contractors in Springfield, MO have agreed that there are actually many similarities between push piers and helical piers, such as:
So which methods should a homeowner choose? The first step is to consider the structure you are dealing with. Helical piers are perfect when the soil conditions are known, this is because an installer can know the exact depth the piers can reach. Since the piers don’t rely on the weight of a heavy structure to press them into the soil, these piers are ideal for structures that are not as heavy such as stoops or decks.
- They both can be installed all year-round
- Can be installed from both the interior and the exterior of the foundation
- Are both permanent solutions to structural issues
- Can elevate the foundation back to its original position
- Create next to zero disturbance during the installation
- Are capable of restoring the property’s value
- They are both generally faster installation methods then most methods

How long do helical piers last?
A helical pier is simply put as a foundation pin made entirely of steel that contains helices like a screw does. It is driven deep into the ground, to depths that are deeper than the frost line by a system that is hydraulic. These piers are primarily used for support, they support structures especially where soil conditions are not ideal, making it difficult to set up a traditional foundation system. Instead of a huge excavation, they are thread deep into the ground. They are used to repair the existing foundation that have issues like cracks or are just simply weak. Helical piers minimize the time spent installing a foundation, they cause little to no disturbance in the soil and they transfer the heavy weight of the structure far into the earth to bear the load.
Helical piers can be used for commercial and residential applications. They are often using in caissons, driven piles, and mini piles. They can be very beneficial when the games are to the foundation or the structure is built on soil that is unstable. Such cases where the soil contains a lot of water is a perfect example. You can tell the structure is damaged by the following signs:
Helical piers might also be useful to repair industrial floors. This is because they take a short amount of time, they do not cause a lot of disruption to the daily operations of the factory.

You can tell the structure is damaged by the following signs:
- The plaster walls are beginning to crack on the interior.
- Floors begin to sag and become uneven.
- Window and door frames leave giant gaps when they are closed. You might discover that it is difficult to close the windows and doors.
- Nail pop up in the ceilings
- Basement walls will begin it crack letting in water and creates serious basement flooding.
- You may discover that the chimney is beginning to lean.
