TL;DR
Footing underpinning is the structural repair that extends or strengthens an existing foundation's bearing, either by excavating and pouring new concrete in staged pits beneath the original footing or by transferring the load to steel push piers or helical piles driven to competent strata. It addresses footings that settled on poor fill, expansive clay, or eroded soils, and supports adding stories where original bearing is inadequate.
What it means
Footing underpinning is the structural repair that extends or strengthens an existing foundation's bearing, either by excavating and pouring new concrete in staged pits beneath the original footing or by transferring the load to steel push piers or helical piles driven to competent strata. It addresses footings that settled on poor fill, expansive clay, or eroded soils, and supports adding stories where original bearing is inadequate. The work proceeds in alternating segments so the wall is never undermined along its full length, and a structural engineer's design typically backs the permit.
