|Transferable Warranty Available on Helical and Resistance Pier Repairs
Helical piers are used to transfer loads from the soil near surface to deeper, more suitable load bearing stratum. Helical piers may be used in tension such as for tower guy wires, for tieback retaining walls and in compression for repairing building settlement, and for shear/overturn such as lighting poles or self supporting tower foundations.
Helical piers are round or square, tubular or bar steel shafts with round helix plates welded to them. When the pier is rotated into the ground the helix plates generate an axial thrust, causing the advancement into the ground much like a wood screw into wood.
Brackets are then attached, allowing us to raise the building to a maximum practical recovery.
Although there are additional methods to determine the bearing capacity of the installed piers, the most common is the torsional resistance method which can be monitored during installation.
