Helical Piers offer security and stability like no other new foundation product
But what are Helical Piers?
A helical pier is a steel pier used for additional foundation support when pouring a concrete slab. It is installed before the foundation has been poured, and driven into the ground until it hits load bearing strata. Helical piers are an exceptional way to lock in the foundation of your new home or commercial building.
Put simply, helical piers are the premiere option for securing the foundation of your home.
Who Should Have Helical Piers Installed?
Anyone building a new structure, whether that be commercial buildings or your dream home.
If you’re looking to truly minimize any chance of having foundation problems, we recommend installing a helical pier before your foundation is poured. Combining helical piers with our water management solutions is the best insurance you can have that your foundation will be solid for years to come.
An added benefit of helical pier installation is that it may help you save money while preparing your lot for construction. Specifically, helical piers can minimze the depth required for dirt excavation, installation, and compaction – saving you time and money. In some instances, what you save by not having to excavate will pay for the helical piers in their entirety.
Alongside proper water management, helical piers will give you the peace of mind that you have done everything in your power to limit foundation problems in the future.
How is a Helical Pier Installed?
Superior Foundation Services works closely with your foundation contractor, general contractor, and engineer to develop a Foundation Plan that ensures these piers are placed exactly where they need to be for maximum support. We work seamlessly with these subcontractor groups to ensure no additional downtime is incurred on your build project. This means less headache and oversight required from you.
For the install, we drive down until we hit load bearing strata. Other states may have bedrock to anchor their foundations, but Mississippi has blue clay. Calculated in the Foundation Plan, we will drive the piers to the desired depth in the blue clay and anchor the pier’s footing with concrete for added support and durability.
When installation day arrives, the helical piers are installed via a machine and drive head – similar to an auger – that drives the pier deep into the ground (remember that the deeper the pier can go into the ground, the more stable it will be for supporting the foundation). Then, each pier is connected with two stainless steel bolts, and they are ready to have the footings of your new home poured around them for maximum support.
After the install has taken place, you should have even more peace of mind knowing that our helical piers are backed with a 10-year warranty. This warranty is for the address – not just the customer – so if a homeowner sells their house, the warranty will transfer to the new owner.
Foundation Piers Installation Process
Drilling the hole
The installation process begins with digging a 2-foot square hole with a shovel. The hole is typically 4-5 feet below the ground level and extends beneath the grade beam.
After digging the hole and exposing the grade beam, the next step is to place a pre-fabricated concreted cylinder at the hole’s bottom, directly under the grade beam. Following this step is the placement of a hydraulic ram between the top of the cylinder and the grade beam’s bottom.
The hydraulic ram will help press the cylinder into the ground. Additional cylinders are added and pressed to the point of refusal. Namely, more force is needed to press the piers deeper than is necessary to elevate the house.
Fitting a concrete cap
Once the cylinders are pressed to the point of refusal, they are fitted with a concrete cap, in addition to more cylinders. Afterward, the house is raised using bottle jacks as close to its initial position as possible. The process of which is done while minimizing unnecessary damage to the structure.
After the house is successfully raised, the gap between the piering and the grade beam is filled using steel shims or concrete blocks.
