Underpinning Melbourne

Have you noticed cracks in your walls or exterior brickwork? While minor cracks aren’t always a cause for concern, large cracks (wider than 3mm) that run diagonally in your brickwork could be a sign of subsidence. This means that your foundations have been compromised which can be caused for a wide variety of reasons. For example, leaky drains that have allowed moisture to get into your foundations and weaken them, trees that have caused the soil to shrink as the roots extract water, or even nearby building work that has damaged the ground around your foundations. If you live near a busy road or train track, then vibrations may have also damaged your foundations over time.
Repairing the foundations of your home will require a process called underpinning to take place. Underpinning involves digging beneath the existing foundations to add support, which will prevent any further movement. The load of the building will then rest on more secure ground, or be spread over a greater area to provide additional support. The work is essential as in the case of buildings with subsidence, the current foundations are not strong enough to hold the building in place. Underpinning is a complex process but one that will restore the integrity of structurally compromised homes.

Why Underpinning Guide Melbourne

We are experts in underpinning.
We work by expanding the base in depth and/or width (depending on the case) so that your foundation sits on a more supportive soil layer, or distributes its load across a larger area.
In underpinning the use of micropiles and jet grouting are common methods among many others that we use.
Cracked walls, jammed doors and warped floors are all signs that your house needs underpinning. Through the process of underpinning, the foundation of a building can be restored by replacing, restoring or adding stumps.
It is important that underpinning services be done by experts who have the skills and experience for the job.
Underpinning Guide Melbourne is your one stop solution for all your underpinning needs. Our skilled team of professionals are experts in stabilising structures and strengthening the foundation of any building.

The Benefits of Underpinning

When you select us to strengthen the weakened foundation stumps, you can look forward to the following benefits:

  • Quick and Easy

    Our contractors use a unique structural expanding material that can be injected into the worn out, cracked concrete stumps. This process can be completed with minimal invasion or excavation of the existing foundation. The contractors pierce tiny holes in the stumps that are around 16 mm in thickness to inject the material. Once the material seeps into the concrete stumps, it fills up cracks and strengthens the foundation. The new foundation then realigns the floors and walls of the house, providing additional support.

  • Clean and Budget Friendly

    The underpinning material that we use is not toxic, does not react to any substances that may be found in the soil, and does not leave any carbon footprint on the environment. There is no trace of the concrete dust that is usually found in the old restructuring method. The result is that your family and house inhabits a clean, clear home even while we work on its foundation. Once the material expands, the misaligned walls and the uneven flooring are re-levelled. This allows lowered project costs, which results in substantial savings for our clients.

  • The Advantage of House Underpining. 

    A house provides a strong, reliable shelter to the people who make it their home. As with any physical structure, the foundations of the house is prone to wear and tear. The concrete stumps of the foundation that support the structure can crack or depress, which leads to uneven flooring, cracks in the walls, or misaligned walls in the case of a brick veneer.

Our Results Speak For Themselves

Why House Underpinning in Melbourne

Most residential structures in Melbourne have been built on concrete slabs or concrete footings. If you are a homeowner in Melbourne, then the first thing you need to do is check the foundation. The structure of your house may be strong and sound, but because of the soil conditions in the city, the foundation stumps could have developed cracks or may have subsided into the soil.

Our team has encountered many underpinning projects where the stumps have subsided into the soil. This happens due to the following reasons:

  • Weather conditions

    Because of the hot and dry weather conditions, the clay content of the soil has dried out, leading to unstable ground conditions that put additional pressure on the foundation stumps.

  • Sandy Soil

    Certain areas of Melbourne have sandy soil, which does not provide a firm footing tot eh concrete stumps, causing them to subside.

  • Water Content in soil

    The shrinking and expanding of water content in the soil also leads to the uneven subsiding of foundation stumps, which causes the floors and walls of the house to lose their alignment. This can result in the doors and windows of the house not closing properly and getting jammed.

Underpinning FAQ

The underpinning knowledge and skills are the fundamental principles, methodologies and skills required to achieve performance outcomes. More specifically the knowledge identifies what a person needs to know to perform the work in an informed and effective manner.

The reasons for underpinning are generally: The existing foundations of the building have moved – this is caused by poor soil or changes to the soil conditions (e.g. subsidence has occurred).

The most common method of underpinning is the mass pour method. This process requires excavating sections in sequence to a pre-established depth below the footing and placing concrete in each pit. Then, this process is repeated until the entire affected area has been underpinned.

Explanation: Pile method is useful in clayey soils and for waterlogged areas and for walls carrying heavy loads. For underpinning very light structures, the piles are driven along the structure and then brackets or cantilever needles are provided to carry the structure.

Widening and strengthening of existing foundations may be carried out by constructing a concrete jacket to the existing footings. The new jacket should be properly anchored to the existing footing and column neck in order to guarantee proper transfer of loads.
