How the Underpinning Process Works

Underpinning works by strengthening and stabilising a building’s foundation to address issues like settling, soil movement or structural instability.


The process begins with a detailed assessment to identify problem areas and determine the appropriate technique. Common methods include excavating beneath the existing foundation and adding additional support through concrete, steel or piles.


These reinforcements extend the foundation to more stable soil layers or spread the building’s weight more evenly.


By improving the foundation’s load-bearing capacity, underpinning prevents further movement and damage. This ensures the structure remains safe, durable and capable of withstanding environmental stresses for years to come.

  • Did you know drought can affect your piers?

    During a long drought clay soils expand and contract. In the cooler, wetter weather they expand but when it’s hot and dry they contract.

    As we have been experiencing a long drought, clay soil under your home may have contracted, causing sinking of your piers

  • Did you know vibrations can affect house piers?

    Many houses in suburban areas are built near construction sites, main roads and railways. Underneath homes located in these areas their piers are constantly absorbing a tremendous amount of impact from vibrations.

    Heavy vehicles like excavators, concrete mixing trucks, trains and planes can cause the ground to quake. These vibrations can weaken soil to the point of house piers losing stabilisation in the soil.

  • Have you checked your house piers recently?

    When was the last time you checked your house piers ? House piers can move or sink for a number of reasons.

    In order to find the correct solution to raise, stabilise or stop them from sinking further you need to understand what happened to the piers in the first place

  • Do you have leaking pipes?

    Soil becomes saturated and weak from excess water. Soil erosion, soil aeration and voids can be caused from water leaking out of broken or unconnected pipes, quite often bathroom and kitchen pipes are the most common culprits.

    This excess water from the leaking pipes will reach the ground causing pooling around your piers which will lead to movement and destabilisation
