- Provides comprehensive reports
- Approachable and informative team

Structural Restoration Services Pty Ltd has 35 years of experience. They’ve proven themselves a great choice through several successful commercial and residential projects.
Their expertise is in using a variety of foundation repair techniques such as mini-piling (use of several tubes spaced for pumping resin underground) and mixing concrete after earth excavation.
This makes them compatible with many properties, especially those with restricted land access and space, such as the commercial district of Adelaide.
One of their previous clients commended the company for providing a comprehensive report and solution plan for an underpinning project on their property.
Moreover, many of their clients appreciate the approachability of their team. They offer detailed information about the property and provide valuable advice for maintaining the foundation’s integrity.
If there’s anything they can improve on, one is in making their fees a bit more affordable. Additionally, there have been instances when they struggled to follow up with some clients after the initial call.

Pros
- Expertise in treating salt damp issues
- Employs many techniques for foundation repair (such as undersetting, chemical injection, and gravity feed treatment)
- More than 30 years of experience
- Provides cost-effective solutions
Cons
- Sometimes has long delays between diagnosing properties and providing solutions
- Has cases of not attending appointment
What makes Tech-Dry SA a great choice for foundation repairs is their expertise in repairing heritage homes. A prevalent problem among these houses is salt damp, which the company has successfully dealt with many times.
Salt damp is a type of foundation damage where the soluble salt within the stone walls and plaster is weakened by moisture.
They employ several techniques, such as chemical injections, undersetting waterproof materials on the soil, and gravity feed treatment. With the latter, resin is fed into the soil beneath your foundation to strengthen it.
Furthermore, they have a thorough and fast process for inspecting properties. They can provide a solution after one visit.
With over 30 years of experience, they have successfully provided many effective solutions for their past clients.
They also aim to recommend cost-effective solutions first. One client said that they advised him to simply have increased sub-floor ventilation rather than do earth excavation to solve moisture problems. This was done within a couple of days!
That said, some clients said that the company had some delay between providing diagnosis and applying the treatments to the property. Also, they’ve had cases of not showing up to their appointments.

Pros
- Team of five for foundation repair
- Solid track record in providing long-lasting and durable underpinning
- Ensures that design of property isn’t compromised
- Good for both commercial and residential work
Cons
- Rude phone service
- Sometimes doesn’t follow up after first call with client
Allenco Construction has one of the largest teams for foundation repair, with 5 on their team working on all their underpinning projects.
What makes them a great choice for foundation repairs is their solid track record in underpinning, particularly with the use of reinforced concrete piers, a treatment suitable for both residential and commercial properties.
This solution, where piers are placed at an equal distance under the property’s foundation, proves to be highly stable, as it’s minimally affected by soil movement. The company further reinforces it by adding concrete and steel for additional support.
From their past work, I also noticed that they’re great at providing work that doesn’t disrupt the design of the property drastically. Specifically, the excavations they do are minimal, and they make sure to consult with clients thoroughly.
However, if there’s a downside to them, one is that some clients complained of receiving rude service from their phone receptionist. Another said that he received no follow-up after his first call with them.

Pros
- Long structural integrity warranty of 10 years
- Team collectively has more than 20 years of experience in underpinning
- Good track record with using two methods for foundation repair (resin injection and concrete underpinning)
- Collaborative with clients
Cons
- Pricey
- Takes about a week to answer website queries
Adelaide Underpinning Group is highly recommendable for those who want to ensure that repairs will be long-lasting. The company’s warranty lasts for up to 10 years.
In addition, their team collectively has more than 20 years of experience.
If you look at their past projects, one thing that is constant with them is that they can work on a tight timeline. This makes them handy for commercial property repairs.
They have a great track record of choosing methods with long-lasting impact on the structural integrity of the property. Specifically, they offer both traditional concrete underpins and resin underpinning, depending on the specific case.
One client who had concrete underpinning on her heritage house praised them for being collaborative throughout the whole process. She was always informed and consulted before steps were taken.
Because of their thorough communication, she was able to budget properly and decide whether the duration of the project was reasonable.
A client who had resin injection on her property at the CBD said that the treatment is still staying solid 3 years after installation.
A drawback with the company, however, is that their fees are pricey. Also, I noticed that they don’t respond fast to inquiries made through their website (takes about a week).

Pros
- Can work on residential and industrial properties such as factories
- 40 years of experience providing underpinning
- Can provide repairs in as fast as a week
- Great at explaining their services to clients
Cons
- Doesn’t respond quickly to requests for consultations
- Takes about a week to respond to emails
Urathane Solution is one of the most experienced foundation repairs in Adelaide, with more than 40 years in the business. They’re also one of the most flexible, as they’ve provided services for residential properties, mining companies, factories, and more.
What differentiates their treatments is their fast process. They can improve your foundation’s integrity within just a week!
They do this through the keyhole method where long pipes are inserted underground to pump resin into the soil.
The method doesn’t require earth excavation materials, ensuring that the floors and the garden’s design will not be destroyed in the process.
One client said that she was able to see instant improvements in her home after the repair. The team successfully patched the cracks in her walls which were brought by her home’s poor foundation.
Urethane’s team is also great with explaining industry terminologies and equipment readings for humidity so clients know what’s happening within their property.
If there’s anything they should improve, one is communication. Their response to consultation requests and emails could be faster.
