Helical piers utilize steel shafted screw piles. The section of lead with one or more attached helixes offers the required bearing capabilities. We at M-3 Enterprises then use
a hydraulic torque motor to screw the piers into the foundation of commercial buildings.
With each method, one or more steel piers get pressed into rock or an adequate soil bearing layer and use a metal head assembly to join to the foundation. After the right bearing layer is reached, every pile gets tested at a force greater than is needed to hold the building.
Hydraulic jacks connect to the fixed steel piers and are utilized to elevate the foundation to its initial position. After the edifice is replaced back to the desired place, the piles are affixed (welded or bolted) with wall brackets—securing the new height of the construction.
Piers offer a cost-effective solution for smaller structures as well as pre-fab buildings.
Benefits of Concrete Foundations Piers in Chicago
The advantages of making use of piers to restore a foundation include:
• Reduced expenses—up to ten times more cost-effective than reconstructing the foundation
• No disturbance or loss of the building’s use
• The restoration is handled while the building is being used normally
• Fixes both the origin of the settlement problem (shifting soil) and the outcome (building being out of level) in a single step
• The equipment’s transportable and can easily be used in cramped spaces or moved manually when access is an issue
• No heavy equipment
• No yard destruction
Helical Piers in the Greater Chicago Area
Helical piers utilize screw piles that have steel shafts. One or more helixes attaches to the lead section to offer suitable bearing abilities. Such piers are turned into the foundation using hydraulic torque. Extensions with no helixes are incorporated throughout the driving process.
This process has been proven to work successfully in supporting structures in almost every soil condition. This system can be utilized for stabilizing foundations with slabs constructed on problematic soil as well as tieback anchoring, seismic protection, fixture anchoring and deadman anchoring.
