Great Lakes can solve your sagging and leaking problems. Pressure Grouting is a process of filling voids or fissures in foundations, under machinery, under roads and highways, and in and around sewer lines. Grouting material is typically cement based but other materials may be applicable and preferred based on the job and its conditions. Grouting will strengthen and restore the substrate.

When voids were detected under their holding tanks, Valero Energy called on Great Lakes to restore the integrity of the tanks base. Great Lakes grouting of the tanks included machine based pressure grouting and epoxy based grouting.
