Screwed to a torque value, a helical pier finds competent soil below the layer that softens when wet.
Under Warner Robins the sandy loam sits on a clay hardpan, and that hardpan softens considerably when it is saturated. A footing bearing on it is fine in October and carrying less in March, which is where a lot of the settlement here begins.
A helical pier goes past that. It is turned into the ground with a torque motor until the resistance says it has reached material that carries the load in any season, and that value is recorded for each pier individually.
The install suits this town for a second reason. Access is often tight around base-era homes, and the equipment for helical piers is compact enough to work in a side yard. It also needs no structure weight to react against, which makes it the right answer for porches and additions that a driven pier cannot support.
Here is what our helical pier installation work includes on a Warner Robins home, in town or out toward the Houston County line.
