Advanced slope stabilisation techniques
Advanced slope stabilisation techniques are also known as slope protection or slope reinforcement. Slope stabilisation is a ground improvement measure that prevents or mitigates the erosion, instability or failure of natural or man-made slopes.
There are many ways to carry out slope stabilisation, including retaining walls, gabion structures, ground anchors and rock bolts. The right slope stabilisation strategy will depend on a variety of factors, but Mainmark’s Teretek® resin injection is the answer for projects that require a highly effective solution that can be implemented quickly and with minimal disruption.
Our slope stabilisation methods:
- Are non-invasive and can be implemented swiftly
- Are environmentally inert
- Improve soil cohesion
- Enhance the ground’s load-bearing capacity
- Reduce the risk of slope failure on hillsides, embankments, cliffs, road cuttings and construction sites
- Create a stable soil mass that can last for decades, reducing long-term maintenance and repair costs
- Help to protect people, buildings and infrastructure
Mainmark’s ground engineering technologies use surgical precision and polymers, or cementitious grout, in a controlled process. The material fills voids, cracks and fissures to provide reliable slope stabilisation.
Why is slope stabilisation necessary?
The main point of slope stabilisation is to ensure a slope embankment, culvert or cutting has a sufficient factor of safety (FoS). The FoS quantifies the strength of a soil mass in comparison to the combined weight of the soil mass that makes up the slope and any additional superimposed loads. Commercial structures constructed on or near man-made or natural slopes may necessitate measures to ensure that the slope’s factor of safety is maintained at the specified level throughout the design life of the structure.
Slope stabilisation also aims to overcome common causes of slope failure. These can include:
- Slopes that are too steep
- Water movement and inadequate drainage
- Soil composition
- Erosion caused by flooding or drought
- Fractures or cracks in the ground
- Seismic activity
- Heavy traffic
- Excessive loading
- Historic land use, such as mining
Mainmark’s slope stabilisation techniques deliver fast and precisely controlled outcomes that can be tailored to meet the unique requirements of each project. This flexibility includes variations to the strength and density of the filling materials as required. The result is a robust and dependable slope, ensuring long-term safety and stability.

Teretek® – Resin injection for slope stabilisation
Teretek® is an engineered solution for slope stabilisation 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.

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 50 years.
Is it safe and environmentally friendly?
Injected Teretek® and JOG materials are environmentally inert and have no detrimental effects on the environment.
