About Us

Mainmark Ground Engineering (UK) Ltd is part of the Mainmark group of companies – an award-winning, privately-owned company headquartered in Australia – and services projects throughout the UK and across Europe. Companies of the Mainmark group present creative, effective solutions to many types of ground engineering problems in a wide range of sectors such as residential, industrial, commercial, civil engineering and mining.

The Mainmark group have over 25 years’ experience spanning over 30,000 projects using world-leading ground engineering technologies to achieve safe, accurate and economically delivered outcomes. Mainmark was established in 1995 by Philip Mack, owner and chairman, focusing on bespoke solutions for earthquake repair and remediation, and has more recently diversified and grown to be a globally recognised ground engineering and asset preservation company.

No single method can provide the solution to every ground engineering problem, so we have developed a range of our own state-of-the-art proprietary technologies.

As part of post-earthquake remediation in Japan and Christchurch, New Zealand, Mainmark developed specialised expertise in JOG Computer-Controlled Grouting which has since been proven in Australia and the UK for raising large complex structures. More recently Mainmark has developed Teretek® engineered resin injection solution utilising our proprietary deep-lift and void-fill methodologies. The deep-lift method is unique in that it both raises, re-levels and re-supports structures, and increases ground bearing capacity in the one process.

The Mainmark group of companies has a global footprint across 14 locations with more than 200 staff worldwide. Our aim is to be the best at solving your structural settlement, subsidence and ground problems with a minimum of disruption to your life or business.

Our materials

Mainmark technologies are built on the strength, longevity and versatility of cementitious grouts and expanding geopolymer resins.

Mainmark offers unique and innovative engineered products and solutions

TERETEK® RESIN INJECTION SOLUTION Our proprietary two-in-one solution that delivers both improved ground bearing capacity and re-levelling, backed by a 20-year product warranty. Teretek® engineered structural resin injection raises, re-levels and re-supports sunken building foundations fast, economically and with minimal disruption to occupants. Building footings are raised and returned towards level rapidly, without the need for expensive demolition or excavation.

JOG COMPUTER-CONTROLLED GROUTING This unique computer-controlled system is extensively used for re-levelling large and complex structures, such as multi-storey residential and commercial buildings.

TEREFIL® Our advanced structural lightweight polymer modified cementitious grout, Terefil®, can solve a wide variety of geotechnical challenges in the construction, infrastructure, and mining sectors. This versatile engineered material is ideal for use as a fill in situations where cellular concrete, foam concrete or foam cement would otherwise be applied. T

Mainmark equipment

Our equipment

Our site operations require a relatively small footprint – for resin injection our plant and equipment is fully self-contained within one or two trucks and for JOG one or two shipping-type containers. For all but the simplest projects, progress is monitored using laser levels or fully integrated, robotic survey stations. We can also assess sub-soil conditions before and after restoration by using portable hand-operated dynamic penetration devices, without need for vehicle access.
