Expansive clay opens cracks every wet season and closes them every dry one, until they stop closing.
On Lizella clay a crack often behaves seasonally before it becomes permanent. It opens through the wet months as the soil swells and pushes, closes partway through a dry August, and each year it comes back a little wider than before.
That pattern matters for the repair. A crack that is still cycling will break an injection seal, so sealing while the movement is active gives a short-lived result. The clay has to be dealt with, or at least evened out, before the crack is closed permanently.
So we measure and observe first. Where movement is still active we address the moisture around the foundation with drainage and roof water control, and brace or pier where the wall has moved structurally. Once it is stable, injection fills the crack through the full depth of the wall.
Here is what our basement crack repair work includes on a Lizella home, in town or out toward the Bibb County line.
