Soil stabilisation for improved load-bearing capacity
An adequate foundation is crucial for the long-term durability and safety of a building. When the soil beneath a structure deteriorates, it can result in structural damage and pose safety risks to its occupants. Soil stabilisation is a ground improvement process that enhances the properties of the soil, enabling it to effectively support the weight of the building or infrastrcture.
Mainmark has been providing ground engineering solutions around the world for more than 25 years. We offer reliable and value-engineered soil stabilisation solutions that will restore structural integrity and safety, and re-level the foundation.
Our team of soil stabilisation specialists is skilled in employing various modern and proven ground improvement techniques, including resin injection and computer controlled grouting. These provide a fast, affordable and reliable alternative to traditional methods such as mass concrete underpinning or piling.

What is soil stabilisation ?
Soil stabilisation is a term for ground improvement required for many residential, commercial and infrastructure projects across the UK where the ground conditions are not suitable for construction because the sub-grade soil is weak, wet or cohesive and can’t support the foundations of a planned structure.
Soil stabilisation aims to improve the bearing capacity of structural ground layers. This can be done using traditional techniques or by deploying techniques that use chemical binders. The latter produces the desired soil compaction without excavation, material removal and import of aggregates.
Soil stabilisation is frequently deployed on brownfield sites and for embankment stability. It can be used to improve the ground to support floor slab foundations or as a temporary solution during demolition and excavations on site.
Applications besides commercial and residential land development include airport taxiways, aprons and runways, railway embankments and roads, bridges, car parks and pavement construction.
Soil stabilisation technologies
Mainmark soil stabilisation technologies
Teretek® – Soil stabilisation through resin-injection
Teretek® resin injection technology is a swift and non-invasive solution suitable for commercial or residential applications. With the Teretek® resin injection technology method, we drill small holes through the ground-bearing slabs or the foundations into the underlying deteriorated soil strata. Through these holes, we inject our proprietary resin formula, which fills cracks or voids, stabilises the ground, and, if needed, restores the structure to its correct level. Soil stabilisation projects using Teretek® resin injection technology. can be completed with minimal disruption.
Soil stabilisation with JOG computer-controlled grouting
Mainmark utilises its award-winning JOG computer controlled technology for improving foundation soils and re-levelling foundations for larger and more complex residential and commercial structures. JOG computer controlled grouting employs a high-mobility cementitious mix. The grout is pumped into the required injection depths to gently raise the structure. The process is meticulously monitored and controlled using laser sensors and computers, allowing for precise and incremental lifting. By minimising differential stresses, this method ensures exceptional levelling accuracy.

Mainmark technology benefits
Benefits of Mainmark’s treatments for soil stabilisation
Speed of operations
Contrasting traditional underpinning, our soil stabilisation methods can be carried out quickly, with many projects taking just a day to complete.
With resin injection and computer-controlled grouting, the building can remain occupied and its contents can remain in place.
Mainmark’s soil stabilisation techniques cost a fraction of traditional underpinning.
Our methods are environmentally inert and have no detrimental effects on the environment.
With over 30 years of experience in soil stabilisation and ground engineering, Mainmark has built a rich portfolio of thousands of successful projects using our geopolymer, which has a design life of more than 120 years – and all projects are backed by a 20-year warranty.

Soil stabilisation FAQ’s
What happens with unlevel driveways, floors and hardstand areas?
After the application of the Mainmark solution, unlevel surfaces will become aligned again as the ground underneath is strengthened and re-supported. Simple cosmetic repairs may be required.
Will there be a mess?
Very little, if any. We use Teretek® engineered Resin Injection technology, which is likened to “keyhole surgery”, or JOG Computer-Controlled Grouting, with no major excavation and minimal disruption or mess. The injection holes required are very small.
How long does it take?
Each project is different and depends on the required amount of lift, area for correction, building construction, and ground conditions. Most projects can be completed in a day or two, and we can work at night or on one area at a time, so your business can keep operating.
Do i need to send my workers home?
No, most projects don’t require you to vacate the premises or even move furniture or equipment. For the most part, you can keep operating as normal. Driveways can often be driven on in as little as 30 minutes after treatment.
What warranty will I get?
The materials we use have been developed for use underground and have been specifically engineered to resist shrinkage and deterioration. Teretek® is warranted by Mainmark for an industry-leading period of 20 years.
Is it safe and environmentally friendly?
Injected Teretek® and JOG materials are environmentally inert and have no detrimental effects on the environment.
