What is Underpinning?
Underpinning helps stabilise your home’s foundation and arrest further movement. With underpinning, our experts strengthen your home’s foundation to ensure it rests on supportive and stable soil while evenly distributing the house’s weight. The end result is a stable foundation ready for a renovation project.
Underpinning is critical for homes that are built on unstable soils. If your foundation has weakened due to flooding or erosion over time, Underpinning can strengthen the foundation of your house and offer peace of mind. However, it is a comprehensive and complex procedure that should only be performed by underpinning specialists who are trained and equipped for the job.

Benefits of Underpinning
The Foundation Repair Options
Our foundation repair services are designed to make underpinning transparent and easy to understand right from start to finish –
Underpin & Hold
The underpinning process starts with ground preparation and excavation of the foundation. Once it is completed, we start pouring the concrete underpins. In the case of underpin and hold, the structure is supported where it is and is not lifted. This will arrest any further movement.


Underpin & Lift
The second stage involves lifting the section being underpinned to close up cracking. Once it is completed, our experts concrete the foundation at the new height, locking it firmly in place.

Does my House Need Underpinning?
Before we get into whether your house needs Underpinning, let’s quickly check some of the causes why your house may move:

Tree roots near foundation

Soil Moisture Content Changes

structural design for soil type

Broken water pipes

Poorly compacted soil

Soil Consolidation
Now that you understand some of the causes why the house footings might be loose, you might be curious about learning how to recognise the signs that your building needs underpinning. Typically, the first signs that underpinning is needed for your house include –
- External cracked bricks
- Internal cracks in the plaster
- Uneven or cracked floors, slab or tiles
- Gaps between walls and windows
- Doors and windows jamming
- Cracks in the concrete surrounding your house
- Water pooling around the house
If you face any of the issues above, our qualified experts are here to help! We can arrange a site inspection and provide a no-obligation quote for the foundation repairs you might need.
Concrete Underpinning vs. Resin Underpinning

Underpinning Contractors use different methods for underpinning, but the reason for the works is the best indicator of the type of method to be used. Two of the most popular ones are concrete underpinning and resin underpinning.
When it comes to foundation repairs, traditional concrete underpinning has been the trusted choice for many years. In concrete underpinning,, underpins are dug and poured below the existing footing and is used to support the structure.. In resin underpinning, the resin is injected into the holes bored into the ground around the foundation that is absorbed by the surrounding soil and makes them less reactive.
You need to be cautious of using any method for repairing foundations that have been around only for a short while. Resin underpinning may sound like a simpler and faster underpinning method, but it does not guarantee your foundation issues are resolved permanently the very first time. A failed resin injection procedure means the additional cost as it creates further movement to previously repaired internal walls and tiled areas. Thus, you need to be aware of these critical factors when deciding which method to use for underpinning. It’s worth noting that once resin injection is performed, traditional concrete underpinning cannot be used.
How Much Should Underpinning Your House Cost?
When you discover your home might be suffering from subsidence, it can be unsettling and leave you panicking about the underpinning cost. But it does not always spell disaster. The good news is that most subsidence issues can be solved quickly.
The total underpinning cost will depend on a number of factors such as –
- Location of your house
- Type and profile of building footings
- The actual cause of the problem
- Nature and the condition of the foundation soil
- House surroundings
- The volume of materials needed
- Amount of time the work will take
