Abstract
In a method and apparatus (710) for treating soil at a work site, a high pressure application tool (712) is connected to a base unit (714) and moved relative thereto along a first area of the work site adjacent a structure (94) and operated to inject soil treatment down into the soil along the first area of the work site. A low pressure application tool (711) is interchanged with the high pressure application tool (712) and moved relative to the base unit along a second area of the work site adjacent the structure (94) and different from the first area of the work site. The low pressure application tool (711) is operated to apply soil treatment to the soil along the second area of the work site.
