Mass Stabilisation

Mass Stabilisation

Mass stabilising is a highly efficient way to improve very low strength, high moisture soils. Our team of highly trained and proficient professionals are experts at implementing stabilization using both dry and wet grout binders. Our track record covers a wide range of high moisture content soils, including alluvium, lake deposits, peats and contaminated soils. GeoStabilization’s state-of-the-art, computer-controlled technology allows load cells on the tank to accurately control, measure, and record the mix and delivery of dry binders, to ensure target application rates are achieved. GPS positioning controls ensure consistent application in the areas requiring stabilization.


In-situ Mass Stabilisation (IMS) is a fast and effective way to permanently strengthen high moisture, low strength soils. More effective than traditional shallow in-place stabilising, in-situ stabilising creates a stabilised block by mixing binders with in-situ soils. Mobile equipment offers a cost-effective solution that removes the need for costly dewatering and saves on the cost of bringing in new materials and disposing of unsuitable materials to landfill., reducing the carbon footprint for many construction sites Suitable for a range of soil conditions, in-situ stabilisation achieves mass stabilizing to a depth of 5 metres, and has been adopted for a range of permanent and temporary applications from tunnel access shafts to residential ground improvement solutions.

The excavation, treatment and replacement of low strength soils can also be treated with specialist ex-situ equipment. Low strength soils are given improved stability, impermeability and load-bearing strength. The process delivers significant cost savings by removing the need to bring in new soil or dispose of existing soil, reducing a site’s carbon footprint.
