In this issue of Building & Construction Review, we would like to recognise Mainmark for its Commitment To Excellence.
Mainmark Ground Engineering (UK) Ltd is a specialist provider of non-invasive ground improvement and foundation repair solutions, operating as part of an internationally recognised group with more than 82,000 completed projects worldwide. With its UK headquarters in Milton Keynes, the company has expanded its presence in recent years with operational hubs in Hampshire and Greater Manchester, supporting a growing nationwide demand for its services.
In 2025, Mainmark further extended its reach into the Republic of Ireland in response to the country’s increasing subsidence risk. Unlike the UK, where subsidence is largely linked to clay shrinkage and swelling, Ireland’s more varied geology presents a wider range of substructural challenges, including flood-related instability, settlement and void formation. These conditions can make subsidence cases less predictable and, in some areas, more severe – reinforcing the need for advanced, adaptable ground engineering solutions.
At its core, Mainmark focuses on delivering cost-effective, low-disruption solutions for issues such as subsidence, underpinning, re-levelling and slab lifting across residential and commercial properties. Recognising that no single method can address every ground engineering challenge, the company has developed a suite of proprietary technologies. These include its JOG Computer-Controlled Grouting system, designed for the precise lifting of large and complex structures, and its Teretek® resin injection technology, which enables structures to be raised, re-levelled and re-supported while simultaneously improving ground strength and filling voids. Additional innovations such as Terefil® – a lightweight cellular concrete used for soil replacement and void filling – further enhance its capabilities.
Operating across sectors including residential, commercial, industrial, civil engineering and heritage, Mainmark is known for its ability to deliver effective solutions in sensitive or high-risk environments where minimal disruption is essential.
General Manager Tom Kavanagh highlights the importance of both innovation and expertise, “Our team is what truly sets us apart – passionate, experienced professionals who plan and deliver every project with precision. From major infrastructure schemes to individual homes, we’re focused on providing best-value solutions while minimising disruption. Innovation is central to that, particularly with technologies like Teretek®, which has been developed to deliver highly accurate ground improvement outcomes.”
A significant area of focus for the business is the insurance-backed sector, where it works closely with insurers and loss adjusters to resolve subsidence claims efficiently and sustainably. In addition to his role at Mainmark, Kavanagh is Vice Chair of the Subsidence Forum Committee, a leading UK industry body. He notes, “There is a need to rethink how subsidence claims are managed to help future-proof homes against climate change. We’re also supporting initiatives addressing empty homes, many of which are increasingly affected by subsidence.”
Mainmark is also involved in major commercial developments, including its work at 2 Finsbury Avenue in the City of London. There, its low-impact ground stabilisation techniques have enabled pre-construction works to proceed safely in a dense urban setting, minimising disruption and protecting surrounding structures – demonstrating the precision and reliability of its approach.
With continued investment in innovation and expansion, Mainmark is well positioned to meet evolving ground engineering challenges, delivering sustainable, low-impact solutions that support the resilience and longevity of buildings and infrastructure.
