Underpinning a house
At the heart of our journey lies the trust of thousands of businesses worldwide, reflected in the numbers that drive us forward.
Are you considering underpinning your house?

Traditional methods of underpinning a house aim to improve the ground under the foundations. It is usually a treatment for subsidence or other problems with the soil beneath your home.
Underpinning a house can be a complicated, lengthy and costly process. The good news is, it’s not the only option for residential properties. Here at Mainmark, we provide fast, non-invasive and reliable solutions to common problems associated with ground movement or poor soil quality under your home.
Our Teretek® engineered resin injection technology and JOG computer-controlled grouting solution are alternatives to mechanical jacking and other traditional house underpinning solutions and can be used to provide:
Ground improvement – Our technologies can increase load-bearing capacity and mitigate liquefaction under existing homes.
Lifting and re-levelling – Resin or cementitious grout is injected under the foundations,
bringing your home back to levelVoid filling – Injecting resin or cement into voids within the soil will help to support the
foundation.
If you’re considering underpinning a house due to poor soil quality, subsidence or other problems, Mainmark’s award-winning solutions may be a better choice.
Our technologies are quick to implement, cost-effective and result in minimal disruption to you and your family – giving you peace of mind that your home is safe and on solid foundations.
How underpinning a house works

The process of underpinning a house can be expensive, time-consuming and a messy project. It involves excavating the soil underneath the foundations, removing it from the site and replacing it with concrete.
During the underpinning process, residents will need to leave their homes – usually for several weeks – and they may need to remove all their belongings as well. There are also implications upon return as the process can be messy and will require remediation work, whether it is gardening, patio or decking repairs or redecoration of rooms in a home.
Mainmark technologies speed up and simplify the project significantly. Our solutions can be implemented within just a day and there’s no need for the family to leave the house or pack up their things and move to alternative accommodation.
As opposed to underpinning a house, Mainmark solutions are quick, clean and cost-effective. They involve drilling small holes beneath the foundation and sometimes through the floors within the home. Then a resin or cement is injected during a controlled process and can:
Gently lift and re-level the house
Improve and strengthen and compact the soil

Once our engineers have completed the work, the floors can be walked on immediately and cars can be parked on drives straight away.
There is no need to restore your garden and patio and wall cracks can close slightly as the home is re-levelled. Redecoration may be needed to make your house look new and fresh again.
Mainmark technologies – modern alternatives for underpinning a house
Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.

Teretek® – Resin injection underpinning alternative
Teretek® is an engineered solution for re-levelling subsided buildings that utilises a plural component, expanding polyurethane resin. The expansion force of the material results in the controlled lift of structures, with a by-product of localised bearing capacity improvement through soil densification.

JOG computer-controlled grouting underpinning alternative
JOG computer-controlled grouting uses a multi-point injection technique to insert cementitious grout materials under foundations. It can be used under commercial and residential buildings ranging from single-storey shops to high-rise structures. The injected materials have a controlled set time, which allows for the precise lifting of a structure.
