Brisbane Underpinning

Underpinning services are crucial when the foundation of your property is unstable or has been weakened due to factors like soil subsidence, tree root invasion, or inadequate original construction. These services help strengthen and stabilise the foundation, ensuring the safety and longevity of your building.

At Raise + Relevel, we understand the importance of maintaining your home’s or commercial property’s structural integrity. We are a leading provider of Brisbane underpinning services, delivering high-quality solutions to homeowners, businesses and public buildings throughout Queensland.

Every building is unique, so we tailor our approach to your needs. With Raise + Relevel’s underpinning contractors, you can trust that your property’s foundation is in good hands.

What is underpinning?

Underpinning is a process that involves strengthening the building foundation of an existing structure. This becomes necessary when the initial foundation lacks the strength to bear the building’s weight, perhaps due to changes in the soil’s bearing capacity or moisture content or when additional floors are added to a structure. It is a crucial aspect of building defect repair and foundation solutions.

Think of underpinning as providing your building’s foundation with additional support. Various techniques are involved, each tailored to address a specific foundation issue. The chosen technique depends on the problem at hand, the nature of the soil, and the building’s structure.

Underpinning is a job for professionals; it needs precision and experience. That’s where we come in. Our team at Raise + Relevel is equipped to handle any underpinning project, ensuring your building’s foundation is solid and secure.

Why is underpinning important?

Underpinning helps keep your property safe and preserves its value. It fixes subsidence, leading to unlevel buildings, cracked walls, sinking concrete slabs, and jammed doors or windows. These small problems can become bigger, more serious structural issues if not addressed.

By reinforcing your foundation through underpinning, you can stop these problems from worsening. This keeps your property safe and helps maintain its market value. A well-kept building with a strong foundation is more attractive to buyers than one with unresolved structural issues.

Plus, underpinning can also make your property look better. Cracked walls and uneven floors aren’t just safety hazards; they also take away from your building’s aesthetics. Fixing these problems through underpinning can enhance your property’s appearance, making it more appealing to potential buyers or tenants.

For efficient house raising and house subsidence solutions, our underpinning services in Brisbane, Gold Coast, and Sunshine Coast can definitely help with fixing any underpinning structural issues and assist with strengthening the foundations.

How much does underpinning cost in Brisbane?

The cost of underpinning Brisbane and surrounds can vary depending on several factors, including the project size, the type of underpinning method used, and the complexity of the work involved. At Raise + Relevel, we pride ourselves on providing cost-effective solutions without compromising quality.

Different types of underpinning

Underpinning is a technique used to strengthen and stabilise the foundation of a structure. Several underpinning methods are suited to different types of projects and soil conditions.


Micropiling is an innovative underpinning method that involves drilling small, deep holes into the ground beneath the structure. These holes are then filled with cement grout to create a “mini piles” network. This network acts as a new foundation, helping to distribute the structure’s weight more evenly across the ground. 

Micropiling is particularly useful when the soil is unstable or the access to the site is restricted. It is also preferred when vibration and noise need to be minimised.

Concrete slab underpinning

This is one of the most traditional methods of underpinning. It involves excavating sections beneath the existing footing and pouring concrete to create a new, stronger foundation. The process is repeated in sections around the building, or ‘pins,’ until the foundation is reinforced.

Concrete slab underpinning is a tried and tested method often used in residential properties. It’s best suited for structures where the original foundation is shallow and the underlying soil can support the additional weight of the concrete.

Pier underpinning

Pier underpinning, or pile underpinning, is a more modern approach. This method uses hydraulic jacks to lift and stabilise the building, relieving pressure on the compromised foundation. 

Once the structure is secure, concrete or steel piers are driven into the ground at key points around the foundation. These piers act as new supports for the structure, transferring the load from the existing foundation to more stable underground soil layers.

Pier underpinning is often used in cases where the soil beneath a building’s foundation is highly unstable or where a significant increase in foundation depth is required.

When do you need underpinning?

There are several signs your property may need underpinning repairs:

  • Subsidence: If your house or building is sinking or tilting, it could be due to poorly compacted soil or leaking pipes beneath the foundation.
  • Uneven floors: If your floors are not level, it could indicate an issue with your house’s foundation.
  • Cracked walls: Wall cracks, particularly large, horizontal ones, often suggest a problem with the building’s foundation.
  • Doors and windows that don’t open and close properly can signify a shifting foundation.
  • Leaks in the basement or foundation: Persistent leaks could indicate a problem with your property’s drainage system, which can cause erosion and weaken the foundation.
