What is Underpinning?

Underpinning is a building technique that is used to repair and restore building foundations that have become unstable. It is a specialised process that should only be carried out by a foundations expert. It involves investigative digging to identify the cause and location of the problem, engineering expertise to design and certify an appropriate solution, and building expertise to lay the new structural elements that will underpin the house.

This instability could present itself as:

  • Cracks in interior or exterior walls

  • Cracks in the concrete slab surrounding your house

  • Sticking doors and windows that have become difficult to open and close

  • Gaps opening up around door frames and windows

  • Floors that appear to no longer be level in some areas of the house

  • Walls have a visible lean to them

There a number of underpinning methods, all of which are aimed at strengthening the foundation in key areas around the house where the instability has been identified. However, not all provide the same results and not all are suited to every foundation problem.

Find out more about when underpinning is needed. 

What Underpinning method is best?

Having some knowledge of underpinning methods will help you make an informed decision when it comes time to get quotes. There are three methods commonly used to provide underpinning:

  1. Concrete slab

  2. Screw piering

  3. Resin injection

Traditionally, concrete underpinning was used to increase the size of foundations and in the process strengthen them. It is still used a lot today.

Screw piles (piers) is the main method used by Foundation Solutions, which combines steel piers with concrete footings to secure the building and lift is back to its original position, closing up gaps and cracks. The use piers is considered a permanent solution - one that will not be affected by further changes in the ground surrounding the house - which is why we use it.

Grout injection is the newest method available. It involves injecting resins into the ground which fill up gaps and expands, compressing the ground. It is the least reliable method in terms of final cost (the amount of resin required can blow out) and suitability to all ground conditions.

Do I need Underpinning on my house?

The most common question people want answered is "when is underpinning necessary". Most people asking this usually have one or more of the following problems:

  • Soil subsidence has led to sinking foundations.

  • Natural causes such as flooding has effected the foundations.

  • The original foundation design was inadequate.

  • Excavations nearby have affected the foundations.

  • Additional weight was added to the building (e.g. a second storey), requiring a stronger foundation.

In each case there will be visible symptoms, such as those listed to the left (e.g. cracks, sinking, etc). The only way to be sure if your house requires underpinning is to talk to an expert. It is a complex matter and can be expensive, so it is not to be taken lightly. Which is why Foundation Solutions readily provides this information up front and at no cost. 

How much does Underpinning cost?

Before you can estimate the cost, you need to understand the extent of the problem with your foundations. That means talking to a few experts first to get some reliable information.

Broadly speaking, the cost of underpinning can range from a few thousand dollars, to tens of thousands, depending on the method used and extent of damage to foundations.

Resin injection is often cited as the cheapest and least intrusive, however the costs can escalate due to the unknown amount of resin needed and there is no guarantee the treatment will work.
