A method for altering a characteristic of the ground. The method comprises the steps of preparing a lignocellulosic material, suspending the lignocellulosic material in a slurry to create a lignocellulosic slurry, The method further includes the step of injecting the lignocellulosic slurry below the surface of the ground into a subterranean aperture. The method also comprises the placement of anchoring devices in the ground to alter at least one force experienced by the ground so that the shape of the subterranean aperture into which the solids are transported is altered.
