Helical Piers - Underpinning
Helical Piering in a nutshell: Helical Piering is a method of lifting or stabilizing a sinking or settling foundation. Your structure relies on the the footing for support, as well as establishing a level platform for building. When the footer stability is compromised, Wall Anchors of Northern Ohio can install Piers much deeper, in a more solid, adequate lifting soil. Once piers are installed in a load bearing stratum, the footer / foundation can be lifted and supported back to normal.
Using the lifting bracket and jacking system, the foundation can be lifted. Once the foundation is lifted back to the desired result, it can then be locked into place. If you have more questions regarding this procedure, please contact one of our consultants for a more detailed explanation.
Wall Anchors of Northern Ohio's piers consist of one or more helical-shaped circular steel plates welded to a central steel hub. The depth of the helical steel piers into the soil is typically extended by adding one or more steel hub extension shafts mechanically coupled together to form one long, continuous pier. Extensions can be with or without attached helical-shaped steel plates. Each helical steel plate is 3/8-inch or 1/2-inch thick and has an outer diameter ranging from 6 to 15 inches.
The central steel hub of both lead sections and extension sections are 2-7/8 inch diameter rounded tube steel.
Wall Anchors of Northern Ohio's piers are available in single, double, triple helix configurations. Helix sizes and bar sizes may be custom ordered in any combination as required for the application. Extension bars are available in 3, 5, 7 foot lengths.
