About Mainmark
Mainmark Ground Engineering (UK) Ltd is a subsidiary of the Mainmark group of companies originally established in 1989. As a pioneering force in the industry, we support Tier 1 to Tier 3 contractors, consulting engineers, local authorities, and property owners with our tailored ground improvement services.
For over three decades we have held an impressive track record of delivering over 80,000 successful projects across the UK, Australia, New Zealand, and Japan. We work across a range of sectors including Residential, Commercial and Infrastructure. With our UK headquarters located in Milton Keynes, we provide a fast, cost-effective, and non-invasive alternative solution to traditional excavation and underpinning methods.
Our ground improvement and level correction methods allow us to raise, re-level and re-support foundation subsidence in British homes. Our service can close cracks in walls, fix jammed windows and doors and restore the equilibrium of sunken floors in your home.
Experienced teams
Our seasoned team of experts are not just skilled – they are passionate about finding innovative solutions for your unique needs. On in-house engineers lead our subsidence treatment plans, and we believe in building trust through working transparency with both price, service delivery and aftercare. We create a bespoke groundwork treatment plan for every job we survey, as no two buildings are the same.
That's why we make a commitment to only promise what we can deliver. We back this up by offering clients with a 20-year product warranty as we feel secure in the longevity of our product and ground engineering methods.
The delivery of our non-invasive solution is a cut above traditional underpinning and piling practices that often take weeks or months and cause significant disruption to households. Mainmark’s innovative practices can usually treat ground foundation in homes within 2 – 3 days and with minimal interference for the household which can continue operating as usual.
With Mainmark, you're not just buying a service, you're investing in a partnership built on expertise and integrity that will stand the test of time. We don't just fix foundations; we build a solid ground for peace of mind.

What our clients say
‘’We used Mainmark recently. They were so professional. They attended to the job at hand, were a pleasure to have around. They were clean and were able to explain the job clearly, answer any questions and discussed any changes with us. I was impressed with the way they kept an eye on our drains and our neighbours drains due to the proximity. Upon completion of their work, they walked through my house to check that the doors opened and closed and that my windowsills were straight’’
Watch a video case study
If you like what you have read about us and want to learn more, please view our video case study on our YouTube page that shows how our teams treated the sea wall around this coastal property. Our Teretek resin product was injected into the ground surrounding the parameter of the wall, inserting solution into the areas that were weak. We completed this job in one week.

Facilitating excavation
Mainmark technology can be used to provide temporary works solutions to enable deep excavations to prevent the existing soil strata from collapsing under homes.
This is a great alternative to using traditional methods where essentially the weak ground would need to be completely dug out resulting in extra time, money, and disruption.
Our team uses the quicker resin injection method to fill the voids between the soils and bond the particles together to create a solidified mass. This strengthened ground can be used to support increased load, perfect for if you’re adding additional floors, stabilise sunken structures, such as cracks or brick separations between your home and extension, or create temporary shoring solutions for larger property or complex projects.
Increased load bearing
When undertaking a refurbishment of your structure you may be looking at adding extra weight on top of your home, such as a roof extension, or adding another floor. Mainmark’s techniques improve the soil bearing capacity under your home which helps safeguard the safety of your project and allow for operational continuity of the work. The aim is to help you retain your property valuable and give you the freedom you need to conduct your home renovation plans.
