An apparatus and method for injecting grout is described as having an injector body with at least three holes therethrough for conveyance of a first, second, and third fluid as desired. One of the fluids is a resin and another is a catalyst which when combined, chemically react to produce a first chemical grout. A third fluid is an additive which, when combined with the resin and the catalyst, modify at least one characteristic of the first grout that is being produced. The introduction of the additive is controlled as desired at the surface to provide a continuous (monolithic) pour having variable grout characteristics. According to a modification, the additive is replaced by a second resin which when combined with the catalyst produces a second type of a grout having at least some characteristic that is different from the first grout.
