A system for forming a structure having load-bearing capabilities is provided. This system includes a material capable of conforming to a desired shape and an activator that includes a pre-measured amount of fluid. Both the material and the activator are contained within an activator-impervious sealed pouch. The pouch is clamped or sealed so as to isolate the conformable material from the activator by creating two separated areas within the pouch. In use, a device clamping the pouch is removed or an internal frangible seal of the pouch is broken so as to allow the activator to be mixed with the conformable material. Following this, the pouch is opened, and the activated material is removed. The activated material then may be applied to a surface where it hardens and forms a structure having load-bearing capabilities.
