13. A method for the reduction of liquefaction potential within soil of a stratum having a thickness and being located a distance below a surface, comprising:
providing a plurality of injectors, each injector of the plurality of injectors having a proximal portion and a distal portion, the distal portion having a perforated outer wall;
inserting the plurality of injectors within the soil;
locating the distal portion of each of the plurality of injectors within the stratum; and
injecting a predetermined mass of a two-part polymer liquid down each of the plurality of injectors and into the stratum via the perforated outer wall of the distal portion so that the two-part polymer liquid permeates the stratum forming a tacky foam which cures to a solid foam matrix comprising particles of the soil within the stratum, the predetermined mass of the two-part polymer liquid being determined based on at least one or more soil properties of the stratum.
