WHAT IS GROUND INSTABILITY?
Ground instability is a propensity for the ground to experience upward, downward or lateral movement. This can cause soil movement and slippage which often requires stabilisation prior to conducting excavation for buildings.
WHAT CAUSES GROUND INSTABILITY?
Instability often occurs naturally as a result of the Earth’s constantly shifting crust. However, instability can also be caused or exacerbated by soil compaction, a reduction in ground moisture, excessive excavation or erosion.
