A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanically mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

A soil-cement sampling device and method of sampling soil-cement is provided. The soil-cement sampling device may include an inner tube arranged within an outer tube. The inner tube may be removably connected to the outer tube and may be split into two longitudinal sections removably connected to each other. The inner and outer tubes may be inserted into a recently mixed soil-cement mixture before it hardens and a sample of the soil-cement mixture may be collected in the inner tube after it hardens. Once the sample hardens, the inner tube may be removed from the outer tube and the longitudinal sections may be separated to expose the soil-cement sample for inspection and testing.
