Adjustable Steel Column
Adjustable stumps are a threaded rod added to the top of a steel column. The image below is a house restumping job that required new foundations. The house is not being raised to legal height, but instead is remaining a couple of meters above the ground. In this situation, independent footings are subject to some movement, even with machine dug holes up to 2m deep. This movement is more common in reactive soil types, particularly around Ipswich and further west. These soil types are often referred to as black soil and are notorious for the movement they create inside the house. Hence, this is where adjustable steel columns are very useful, in that they can be moved up or down to allow for changes in soil movements.
