Although there are lots of complicated things about underpinning, the basic concept is pretty simple — it’s the process of strengthening and supporting a foundation. With proper design and installation, underpinning can be used to lift structures to an acceptable elevation and provides vertical support to prevent the area from additional settling.
Here are some examples of why you might need to consider underpinning:
But even the best design and installation is generally not a “fix-all” — there are certain limitations to be considered, such as:
We use a customized approach with superior design and materials. By extending the foundation in depth so the foundation rests on a more stable bearing stratum
which distributes its load to a deeper zone, we are able to
secure and hold the load on a “Rock Solid” foundation.
Power Lift’s piles are driven deep. Unlike shallow concrete methods-pressed concrete segments, drilled or hand dug piers-Power Lift’s piles penetrate unstable soil and provide deep unmatched permanent support. Also, when it comes to restoring a structure, Power Lift is unmatched due to our synchronized lifting systems. By interlinking all our hydraulic lifting points we uniformly raise the foundation to the desired elevation without causing additional distress to the structure and generally greatly reversing damage caused from the original settlement.
