In this video, Michael Masserang is showing us a Charlotte NC commercial building Helical Pier installation but easily could be in the Hickory, NC area.

HELICAL PIER INSTALLATION PROCESS

To stabilize the perimeter of this commercial building (could also be a residential home), 7 Helical Piers(See below) will be hydraulically driven past the looser soils and deep down into the harder load bearing strata. The weight of the structure will then be transferred off of those weaker soils and onto the installed Helical Piers. The process begins by hand digging holes at each point to allow access to the footer. Once the footer is chiseled and prepared, it’s time to place the spreader beam. The spreader beam is placed underneath the foundation and will be connected to the bracket later in the Helical Pier installation process. After the spreader beam has been placed, it’s time to install the Helical Lead Section (also called a “flight”). The Helical Lead is a steel pipe with multiple twisted helix plates ranging in size from 8 inch to 16 inches in diameter. The Helical Lead is placed in the footer hole in preparation of the hydraulic torque drive. At this point the Helical Lead will be connected to a hydraulic drive assembly in the process of driving the helical begins. Designed to withstand 8500 foot-pounds of torque pressure the Helical Lead drills through the weakened soil, typical in the Charlote , NC area, driving the Helical Lead deep into competent load bearing strata. Once the helical has been driven, helical extensions will be added one at a time, until the helical is firmly and securely at the desired depth of installation. Once drilling is complete the excess helical pipe will be cut and be made ready for the bracket installation. The bracket is now placed in position to the helical pipe and set underneath the spreader beam. Once the bracket assembly T pipe is installed we will be able to seat the bracket directly onto the footer. The bracket is now connected to the footer and foundation is ready to be lifted. The bracket is the industry’s strongest foundation bracket, each series of brackets are tested at the manufacturer and provide an unparalleled holding capacity of up to 120,000 pounds. Using a specially designed 20 ton jacking assembly, we begin to jack and slowly lift the home’s foundation. As the commercial building (could also have been a house) is lifted the weight of the commercial buildings foundation is shifted off the damaged soil structure and onto the helical pier. Once we reach the desired correction, the jacking assembly will be removed and the footer hole filled in. This process is then repeated across the perimeter of the commercial building with each pier establishing an immovable connection between the commercial buildings foundation and the deeper load bearing strata deep beneath the commercial building placing your foundation on solid ground.

HELICAL PIER INSTALLATION – WHAT ARE HELICAL PIERS

Helical piers may also be know as screw piles. As both “helical” and “screw” imply, this method employs a spiral-shaped head that is literally screwed into the ground using a high-torque hydraulic motor. The screw provides a bearing surface that transfers the load from the structure to the underlying soil or rock bearing strata. The piers are screwed into the ground in “fights” as needed to provide structural remediation. A “flight” is a section of helical pier. Helical piers have a variety of uses, including slope stabilization and structural underpinning. In slope stabilization, the helical pier may be screwed into the slope past he fault line and attached to a suitable retaining wall to maintain slope stability. In structural underpinning, the failed footings are exposed and helical piers are place underneath the failed footings, which are raised to the desired elevation. Footings, building and piers are secured together using a bracket and the foundation is covered.
