Underpinning is the process of strengthening the foundations of properties that suffer subsurface destabilization — which are movements in the foundation. House subsidence – the sinking of your home’s foundations – is common for properties built on reactive soils like clay, which are mostly unstable due to changes in moisture content.
Underpinning methods are used to increase the bearing capacity of the foundation to withstand destabilization. At times one side or corner of the house may experience more shrinkage or heaving than other parts, affecting the stability of the structure. If it’s subsidence, this will require house lifting techniques to level the foundation of the house.
House underpinning Brisbane foundations is a process that might involve house lifting, and excavation- removal of the surrounding soils – so that it can be replaced with firmer and stable footings, that will withstand underground destabilization, including changes in moisture content.
The techniques for foundation repair work may differ from one property to another and are very often site specific due to different factors. However, when you engage our reputable underpinning specialists, your house is restored to almost its former state, returning the beauty and stability of your property.
We are on a mission to provide reliable underpinning services Brisbane residents require for property restorations. We will not rest until your house foundation has been repaired.
There are various reasons why your house may need underpinning. These include:
Poor drainage
Poor drainage which results in water pooling near the foundation.
Large trees
Large treesnear the foundation suck moisture from the ground
Poor construction
If a property is poorly constructed, it can easily become unstable. Underpinning may be a better alternative compared to a total reconstruction of the property.
Adding a storey to the house
The foundation will require extra support to bear the additional weight of the storey added.
Type of soil your structure is built on
If the soil is reactive, like clay soils, its physical properties are easily affected by elements of weather. Clay expands when wet, and shrinks as it dries. These variations weaken the foundation of a house.

The Concrete underpinning process involves excavating the soils surrounding segments of the foundation in order to increase its strength (known as load-bearing capacity). After excavation, underpins are constructed and concrete is poured and left to cure before it is loaded with the foundation. As the concrete sets and stronger as it dries, it becomes the new foundation. That will increase the depth of the foundation, and the weight of the house is supported from a firm ground, increasing the stability of the property.
The technique has been around for over a century, and is considered to be more efficient and cost effective compared to resin underpinning method. For this reason, it is more commonly used in house underpinning Brisbane among other places around Australia.
There are two methods of concrete underpinning which are:
On the other hand, resin injection underpinning is a simple method that requires no excavation. The technique involves drilling holes into the ground around the foundation and injecting resin under pressure through the holes. It will expand as it dries, binding all the loose soils around the foundation, making it less reactive. However, this method is less preferred because of its associated high risks. For instance, the resin may block any damaged pipes underground, finding its way through any hairline cracks and filling up pipes. Also, if the method fails to stabilize the foundation, traditional methods of underpinning foundations cannot be used. That’s why traditional underpinning is mostly recommended for Brisbane restorations.
The underpins are constructed around the existing foundation. Concrete is poured and left to cure, which holds the structure in position, and stops any further movement.
Underpins are constructed around the foundation, followed by house lifting to level the foundation. Concrete is then poured to secure the structure into place
There are several reasons why foundation repairs are necessary for maintaining the stability of your home. Here are some of the reasons why we’re house underpinning Brisbane:
It is very important to understand the reason for underpinning the property before determining the ideal method for underpinning a house. Mistaking the causes could worsen the problem, complicating the foundation repair efforts. This may lead to an increase in the cost of underpinning a house. For this reason, when slab jacking Brisbane homes that have suffered house subsidence, we start with an inspection by a qualified engineer and order a geotechnical report.
The cost of underpinning a house is high, depending on the nature of the damage. A faulty foundation worsens over time, and could result in increased underpinning costs, or at worst, a reconstruction project. Here is a better way is to spot the warning signs, and fix them, before it’s too late:
If you notice some of these unusual signs, always carry further investigation before deciding on underpinning methods to use. Contact Brisbane Underpinning Group to inspect the property and determine whether foundation repair is necessary.
