Intrusion Grouting

   Many times a structure that needs to be stabilized and or lifted is not capable of the point stresses that piering involves.  Examples of this might be un-reinforced floor slabs or swimming pools.

   By driving an injection pipe deep below the surface and then pumping various types of concrete based grout, the soil itself can be stabilized and even be made stiffer and denser.  This can also be beneficial to fill voids in very rocky soils that traditional piering may not be suitable for. In addition, it is an effective method of stopping underground water movement.

   This type of repair requires deep soil testing by a competent soil testing engineer.  After the soil test are complete an effective grouting plan can then be implemented. The resulting plan will take into effect the various layers of soil and their densities to avoid injecting on top of loose soil and exacerbating the problem by adding weight on top of the incompetent soil.
