Chemical Grouting is another common form of Permeation Grouting that has gained popular acceptance to strengthen granular soils is the injection of chemical solution grouts that bond the individual grains together into tone like masses that are capable of carrying loads of the structures. The chemical solutions typically consist of a base material that is mixed with a hardening agent that causes the mix to harden at a predetermined rate, depending on the compounds used and length of set time desired for a particular application.
Chemical grouting is also commonly extensively used in leaking subterranean structures, to control water flow, and to limit ground movement during excavation and construction ( lagging operation), as well as for footing support, grouted tunnel support and for pit excavation below water.
