Pressure grouting is a solution for achieving soil stabilization for excavation, load bearing capacity, shoring, and erosion control. It is an economical means to correct existing or potential geological and structural problems, consisting of the injection of a liquefied material, under pressure, into voids, cracks, or even between bearing materials and an existing structure.
Except for the area of strength, acrylamides come close to being the ideal grouts, and this is the component indeed which Eckard Brandes Inc. uses in its proprietary soil grout formula.
Chemical grout application is very dependent upon the skill, knowledge and integrity of the firm and operator doing the grout work. It is a process that takes usually place underground or otherwise out of sight, and can only be witnessed in a secondary fashion through CCTV. The chemical gel time can change, extending with ground water dilution and shortening with increased temperature; chemical adjustments are needed to correct the gel time. Eckard Brandes Inc wholeheartedly supports and confirms with the new ASTM standards in this area.
