In-situ soil stabilisation is used throughout the construction industry. This is a quick and cost efficient method of creating ground slab foundations by modifying existing soils with binders such as lime and cement. It is quicker and cheaper than the traditional method of the disposal and import of materials to profile a construction site. Most cohesive and granular sub - soils can be stabilised. Natural soils as well as made ground and recycled materials can be utilised. Stabilisation eliminates the removal of unstable or unsuitable material from the site, such as soft clay or wet sands and gravels, utilising materials onsite to stop import and export of material. Instead the soil can be treated with lime/cement to increase strengths, reduce MCV’s required for structural fill and capping/sub-base layers dramatically reducing the requirements for stone.
