When the soils supporting your foundation system are not providing adequate support, underpinning the foundation system may be necessary. Underpinning usually refers to structurally reinforced concrete beams, pilings (pipe piles), columns (caissons) which are placed under your foundation system to provide adequate vertical or lateral support. Underpinning and other types of stabilization methods are used to mitigate fill settlement, expansive soil, and improperly compacted soil under the foundation.
