Underpinning

Professional Underpinning Services

High-quality property underpinning services

Underpinning is the process of strengthening and stabilising the foundation of an existing building or other structure. There may be any number of reasons why a building may require underpinning, which involves repairing or reinforcing the area underneath the load of the foundation. At JHA Australia, we have an experienced team qualified to provide reliable and sturdy underpinning services to residential and commercial customers in Queensland and New South Wales.

There are a range of underpinning methods and techniques available, depending on the requirements of the particular job. To ensure you make the right choice, it’s important to understand the structure of the foundation, the supports it uses, and what has caused the damage.

For all your underpinning requirements

Underpinning may be necessary for a variety of reasons:

  • The original foundation is not strong or stable enough e.g. due to decay of wooden piles under the foundation
  • The usage of the structure has changed
  • The properties of the soil supporting the foundation may have changed or may have been misjudged during planning
  • The construction of nearby structures necessitates the excavation of soil supporting existing foundations

If you suspect that underpinning might be necessary for your building, then there are certain signs you can look for which indicate a problem. These include:

  • Cracked brickwork
  • Gaps between the window edge and the brickwork
  • Cracked slabs, tiles or floors
  • Floors that aren’t level
  • Misaligned locks and door/window jamming 

It should be noted that not all types of foundation damages can be repaired by underpinning, which is only necessary if the foundation cannot fully support the structure that rests upon it.

Weak and unstable soil is one of the most common factors that leads to unstable foundations, as it may weaken due to weathering or necessary excavations. Changes in the structure might also cause the foundation to lose its structural support.

While underpinning remedial work is intensive and involves some messy procedures, our years of experience at JHA Australia mean we leave almost no trace of our work process. This is the same even when working in small spaces, so if you spot the signs of structural instability, give us a call right away before the damage gets any worse.

It’s always important to establish the cause of the problem and to take remedial action, and JHA is ready to help if you need assistance.
