The TSM or Trench-Soil-Mixing is a method of creating in-situ soil cement structures. KSI soil mixing attachments can be installed on excavators or drilling and piling equipment to achieve production of soil-cement cut-off and retaining walls. Once the blade has achieved the required depth using the moving cutter chain a binder is piped through to the lowest point of the blade and injected into the soil. A mixing process follows until a uniform suspension with the required consistency of soil and cement has been reached. This creates an impermeable, stable soil-cement structure to the required dimensions. Type and concentration of a binder will vary according to compressive strength and permeability levels required. Since this method comes from rock grinding technology, handling small unforeseen obstacles is easily overcome. At the same time, it is also feasible to integrate the soil-cement structure into solid ground or rock.

The blade of the KSI attachment continuously mixes the soil in-situ over the entire installation depth. This ensures that the soil-cement structure is uniformly and thoroughly mixed throughout the installation depth.

The Kemsolid TSM solution is extremely versatile for addressing soil permeability and load bearing issues. It can, for example, be used to seal excavations or contain contaminated areas. It can also be used to seal dams, dykes and other bodies of water as well as creating a barrier to dampen waves travelling from sources of vibration. In trenching and construction of large warehouses, it can be used to improve the soil between supports. It can also be used in applications where new roads are being built on soils with low load bearing capacity or the load bearing capacity must be increased to cope with extra weight or higher traffic speeds. These include some high-speed railway and motorway routes.
