How Soil Instability Develops

Soil instability is a major concern at every excavation site, but installing an appropriate shoring system allows workers to complete projects safely. As you watch the accompanying video, take note of the main causes of soil instability. Soil instability occurs when the downward stress and horizontal support are not balanced.

Unequal horizontal and vertical stresses often occur because of water saturation of the soil, the effects of frost, or vibrations emitted from machinery near the excavation site. It can also occur due to defective shoring systems or poor maintenance of shoring.
