Adelaide Underpinning FAQs

What is underpinning? 

Underpinning is the process of strengthening and stabilizing house foundations or any existing structure. This is done by extending the foundation deeper into the ground or installing additional support around the perimeter of the foundation.

Why would I need underpinning? 

There are several reasons why you might need to underpin your structure or home’s foundation. The most common reason is that the original foundation was not built to support the weight of the structure it currently holds. Over time, this can lead to cracks in the walls and ceilings, doors and windows that won’t close properly, and floors that are uneven. Unattended foundation structure issues might cause your home or building to collapse.

Is underpinning worth it?

That depends on your particular situation. If your foundation is in good condition and you don’t anticipate any major changes to your property, then underpinning may not be necessary. However, if your foundation is in poor condition or you are planning to make changes to your property that would increase the weight on your foundation, then underpinning may be worth the cost.

What are the different types of underpinning?

There are several different types of underpinning, each with its own advantages and disadvantages. The most common types are steel piers, helical piers, and concrete piers. Regardless of your needs, we have the expertise, tools and experience to restore your home’s foundations, and we aim to prevent further cracks and movements.

Why is it critical to request quotes on underpinning or house foundation projects?

When undertaking any kind of building work, it is important to get multiple quotes from different contractors to ensure you are getting the best possible price. It is also worth bearing in mind that the cheapest quote may not always be the best value for money – be sure to check reviews and ask for references before making your final decision.

For the best underpinning yet affordably priced, contact John today.

How long does underpinning last? 

Underpinning is designed to be a permanent solution to foundation problems. With proper maintenance, your underpinned foundation should last as long as the rest of your structure.

What are the benefits of underpinning?

The main benefit of underpinning is that it strengthens and stabilizes the foundation of an existing structure. This can help prevent further damage to the structure and make it easier to sell in the future.

How long does underpinning take?

The length of time it takes to underpin a foundation depends on the size and condition of the existing foundation, the type of underpinning being done, and the accessibility of your property. Generally, you can expect the process to take anything from a few days to a few weeks.

The cost of underpinning a home in Adelaide varies widely, typically between $5,000 to $15,000. However, the price can escalate based on several influencing factors.

  • The extent of Underpinning Needed: If the issues with your home’s foundation are extensive, the cost of underpinning will be higher. The size and number of areas needing reinforcement significantly affect the overall pricing.
  • Access Difficulties: Working on sites with access issues requires additional time and resources, which can increase the project’s cost. Conditions with difficulties with access include but are not limited to narrow passages, steep gradients, or unstable terrains that may hinder machinery movement. Overhead obstructions such as awnings, utility lines, or low building eaves can complicate the process.

Additionally, properties with sensitive areas, such as heritage-listed parts or those with restricted modification permissions, pose unique challenges.

Lastly, high-traffic areas, both pedestrian and vehicular, may require special permissions and result in more complex operations due to public safety considerations.

  • Material Selection: The type of materials used for underpinning can impact the cost. High-quality, durable materials often come at a higher upfront cost but provide long-term savings through reduced maintenance and longevity. Concrete is the most durable and standard material used. Its strength and resistance to compression make it an ideal choice. Steel is another material frequently used due to its tensile strength and stability. Materials like grout and resins have also been gaining traction in recent years for their convenience and flexibility. These materials, when used correctly, can significantly enhance the structural integrity of a building.
  • Labour Costs: Labour cost is another crucial element that affects the overall cost of underpinning. It depends on the work’s complexity and the professionals’ expertise.

A variety of factors can influence labour costs for underpinning. These include:

    1. Geographical Location: The labour cost can fluctuate based on the region or country where the work occurs.
      Scope of Work: If the project is extensive and requires significant time, the labour cost will typically be higher.
    2. Labour Market: The availability and demand of skilled workers can impact costs.
    3. .Materials Used: The type and quality of materials used in the underpinning process can affect the labour cost.
    4. Site Accessibility: If the site is difficult to access, it may require more effort or specialised equipment, increasing the labour cost.
    5. Conditions of the Soil: The condition and type of soil being worked on can affect the cost due to potential complexities during the underpinning process.
  • Miscellaneous Factors: Other factors, such as soil conditions, administrative costs like building permits, and contingencies for unforeseen issues, can also affect the final cost of an underpinning project.

If you want accurate pricing information, contact John at JR Southern Underpinning.

In most cases, yes. Underpinning is typically considered to be a necessary repair to a foundation, and as such, is covered by most homeowners’ insurance policies. To ensure you have full coverage, contact your insurance company.

The type of underpinning you choose will depend on a number of factors, including the condition of your existing foundation, the type of soil you have, and the weight of your structure. A professional foundation repair company will be able to help you choose the best type of underpinning for your particular situation.

Contact John today if you have any questions about underpinning, house foundations, or structural restorations.

The risks of not underpinning a foundation are:

  • cracks in the walls and ceilings will get worse
  • doors and windows won’t close which can cause you more troubles
  • floors will continue to appear uneven and even collapse
  • Not underpinning a foundation can also lead to increased insurance rates and difficulty selling the property in the future.

Worried if your foundation needs underpinning? Contact John today if you need help.

If you notice any cracks in your walls or ceilings, doors or windows that won’t close properly, or floors that are uneven, it’s a good idea to have your foundation inspected by a professional. At JR Southern Underpinning we will tell you if underpinning is necessary.
