Raise and Relevel are Australia’s Specialists in Subsidence-related Remedial Technologies
Need a building raised, relevelled, or stabilised? Raise and Relevel are Australian specialists in subsidence-related remedial technologies for residential, commercial, industrial, and civil structures. The team helps repair sinking floors, cracked walls, unlevel buildings, jammed doors, and unstable foundations using advanced resin injection solutions, void filling, underpinning and foundation repair solutions, water stopping, specialised grouting solutions and structural repair techniques. With teams based in Sydney, Melbourne, and Queensland, Raise and Relevel provides tailored assessments and practical repair solutions designed to stabilise structures with minimal disruption.
Subsidence is the effect of astructure sinkinginto the ground lower than its intended position. This can have a few causes such as water erosion, the presence of vegetation, reactive clay soils, voiding, weak ground or poorly compacted fill and seismic factors.
Your repair depends on more than resin. The person treating your property needs to understand its ground conditions, watch how it responds and know when to pause or adjust the work.
Understand the signs you’ve noticed. Explain what needs investigating and what the proposed treatment can and cannot address.
During your repair
Check how your property responds. Monitor progress and know when to pause, adjust the approach or seek further advice.
After your repair
Check your result against the agreed scope. Explain the measurements, any limitations and what happens next.
Why “ground surgeon”?
Think of the care you would take choosing a surgeon. You would ask about the person, their experience and work like yours. Bring that same scrutiny to the people treating your foundations.
That is the thinking behind our name for an experienced resin-injection rig operator: a ground surgeon.
Experience belongs in the decisions, not just the company biography.
THE WORK WE DO
Raise. Relevel. Stabilise.
Start with the problem at your property. Our subsidence specialists assess the cause and explain the right approach.

I would have to say that Ryan, Damon and Jack from R&R ticked every box that I expect from a good service provider. Outstanding communication, we felt valued as customers even before they showed up on site to carry out the job. They showed up on time and did exactly what the said that they would do, raise and relevel the houses foundations. Ryan, Damon and Jack were very transparent in providing information about what they were doing and why. I seriously can’t fault these guys. We would use them again if required, and have already recommended them to others including our friends. If you want a good job done with no fuss and zero hassles call these guys. It’s that simple. They say what they do isn’t magic, I disagree, we were absolutely amazed by the results.
Pedro and the team were awesome. They did a fantastic job on our house and we were advised of the progress throughout the day. Very professional. We would highly recommend the team to anyone needing foundation work.
Morgan and his team are great with communication and making clear when they'll arrive and what is going to be done, as well as explaining the process and educating you as well. Fast and great work.
Peter from Raise + Relevel came to my house today and was extremely informative. He took the time to listen to my concerns and understand the history of the property before providing a detailed plan and quote on the spot. The quote also included level readings across the house, which helped us fully understand the extent of the issue. Peter was knowledgeable, thorough and a genuinely great guy. I would highly recommend his services and professional approach.

UNDERSTAND YOUR PROPERTY
A closer look. From the ground up.
Explore the symptoms, causes, solutions and results.
The most commonly found symptoms of subsidence are:
1. Sinking Concrete
Slabs which sink or subside can indicate ground movement beneath your house or slab structure. Depending on the cause and extent of the problem, it could affect just a few areas of your home, driveway or the entire abode.
Frequent heavy traffic loads can vibrate slabs or driveways slowly over time. With very slight movements occurring at the slab each time it is driven on, slabs will deteriorate if not supported properly.
R+R utilise a range of modern techniques to mitigate or rectify the cause and symptoms of subsidence. Some are preventative in nature and others are remedially based.
1. Resin Injection
We undertake a modern underpinning technique used on structures whereby we inject structural polyurethane resins to fill voids and compact the weak layers of ground. The polyurethane resin injection first binds the soil with the foundation and then penetrates the soft fill materials and compacts it to the extent that the structure above begins to achieve uplift, thus resulting in relvelling of concrete foundation levelling. The sunken floors are relevelled by injecting structural polyurethane resins through tiny holes. The process will not interfere with your routine or comfort at all.
The presence and flow of water in proximity to footing structures presents a serious risk to the health of the building or slab. Water not only undermines the surrounding strata of a foundation, but it often does so completely undetected for long periods. R+R has extensive experience with polyol, acrylic and cement-based water stopping agents.
Voids in the ground can produce serious damage to a building by removing or reducing the strength of the supporting strata of structural components. R+R have access to a range of bespoke chemical and cementitious materials which we prescribe for project-specific requirements.
Our solutions are not only for under the ground – we also can improve the health of a structure by using crack stitching bars, masonry tie rods, high strength grouts and joint sealers.
R+R utilise a range of modern techniques to mitigate or rectify the cause and symptoms of subsidence. Some are preventative in nature and others are remedially based.
1. Cracks
Concrete driveway relevelled, wall cracks closed, concrete floors are relevelled, and around windows & doors gaps are minimised.
Slab lifting (or slab jacking) ensures that the unlevel concrete is raised to its original level. The strengthened ground offers added stability to the structure. Relevelling means hassle-free closing and opening of doors and windows.
With strategic placement of specialist materials, water flows can be stopped or diverted back to the correct course, and a healthy ground hydrology restored.

Directors
20+ years each
Resin injection and business experience.
Morgan Trainer, Stephen Lyons and Tim Pope bring the technical and business experience behind R+R. Experienced leadership matters when the scope, responsibilities and expectations need to be clear.
Regional partners
20+ years each
Resin injection and local ground experience.
Our regional partners lead the teams in Queensland, NSW, Victoria and Canberra & ACT. Their experience includes the ground conditions in their own region, while recognising that every property still needs its own assessment.
Ground surgeons
5+ years each
Many bring more than 15 years.
Our ground surgeons are the rig operators carrying out the resin injection. Their experience informs how they read the work, respond to site conditions and check progress. “Ground surgeon” describes this skilled operator role; it is not a medical or engineering qualification.
Rig technicians
Learning on the rig
Developing skills under our ground surgeons.
Our rig technicians learn through practical work under experienced ground surgeons. They support the operation and develop their knowledge under supervision, rather than being presented as experienced lead operators.
Years describe relevant team experience, not the age of R+R or a guarantee of a particular result. Ask us who will be assigned to your job.
