Foundation Underpinning

What Does Underpinning Involve?

Foundation underpinning is structural foundation and/or footing support, which LEVELIFT SYSTEMS accomplishes using helical pier screw anchors. Our foundation repair services involve a variety of strengthening and stabilization products including the A. B. CHANCE® Helical Pier Foundation System and FORTRESS® carbon fiber products.

Typical Foundation Repair Applications

When building foundations are placed in problem soils or subjected to extreme moisture conditions or lack of proper drainage, they can shift and settle. Sinking foundations in unstable soil, cracked or buckled walls and uneven floors are problems commonly faced by some quarter-million property owners, often resulting in the need for foundation repairs.

How Underpinning Works…

The Helical Pier Foundation Repair System is founded on the principle of turning an extendible screw-anchor through the unstable upper soil and into the stable, subsoil strata. The load-bearing ability of the underlying soil is continuously measured by monitoring the torque applied to the Helical Pier as it screws through the layers of soil. Once the desired torque is reached, adjustable brackets link the end of each pier shaft to the building foundation or wall it is securing.

When soils below the footing are capable of reasonable lateral shaft support, square shaft (SS) anchors provide required performance.
Where soil strength below the footing is known to be exceptionally poor, pipe shaft (HS) anchors can be used. The Helical Pulldown Micropile or Combo Pile can also be used for extra-high capacity loads or other special applications.
