For many low walls, the weight of the VERSA-LOK units alone resists soil loads sufficiently to work as unreinforced gravity walls. The pinned-unit interlock and frictional forces between units hold the units together so the wall behaves as a coherent structure. The setback, or batter, of the wall face offers additional stability.

The maximum height of an unreinforced Mosaic wall will vary depending on soils, loading and slopes. Generally, with level backfill, good soil and no additional loading, unreinforced Mosaic walls are stable up to heights of 4 feet.
