THE LIFESAVER OF FAILING FOUNDATIONS
CMI installs underpinning to restore sinking buildings or add additional support to failing foundations.
The underpinning process involves excavating to the bottom of the failing foundation and installing helical piles through the unstable soil into stable material. The counterforce bracket system is then installed on the pile and attached to the foundation. Hydraulic jacks are used to lift the foundation to its original state, or stabilize it against future settlement. With the counterforce system, most structures can be lifted to their original elevation. CMI has installed the counterforce system successfully on a variety of projects, from electrical duct banks to very large buildings, and effectively restored foundation soundness.
LIMITED ACCESS SPACES
CMI uses compact equipment when installing Counterforce Underpinning Systems so we are able to work in very tight conditions without adding additional stress to the foundation.
Underpinning using helical piles is optimal for foundation restoration because they are installed without any potentially damaging vibrations or pounding.
