The toe of a wall is the base of a retaining wall, the front bottom edge where the wall meets the ground in front of it and where the wall's weight ultimately bears on the soil below.
Masons and engineers pay close attention to the toe because it's the pivot point for a wall's stability. A wall resists being pushed over by soil pressure behind it partly through its own weight bearing down at the toe and partly through friction along its base; if the soil in front of or under the toe is soft, disturbed, or eroded away, the wall loses that resistance first, before the rest of the structure shows any sign of trouble. That's why the ground in front of a retaining wall matters just as much to its long-term stability as the backfill behind it, even though it gets far less attention.
On sloped lots around the Blue Ridge foothills, we make sure the toe sits on undisturbed or properly compacted soil, not loose fill left over from grading, and we keep an eye on drainage in front of the wall too, not just behind it. Water that erodes soil away from the toe over time, whether from runoff, poor grading, or a downspout aimed at the wrong spot, is one of the quieter ways a wall that was built correctly can still end up leaning or shifting years down the road.
