The Perma Jack® System Foundation Piers
At the beginning of each steel foundation pier is a friction-less end which increases the surface bearing to bedrock and displaces a greater volume of soil as the piering pipe is being driven, resulting in less wall friction during the drive.
Each component utilized in the Perma Jack System is manufactured in the United States of the highest quality material.
Because of the advanced design and simplicity of the Perma Jack System, the lifting of a structure is performed using the same technique, manpower, and procedure. Although some additional time may be required, these advantages with the Perma Jack System make lifting a normal capability of the Perma Jack System.
