We're writing repair specifications for an industrial floor that needs to be undersealed with a cementitious grout to fill voids. Is there a standard undersealing specification that includes requirements for grout, hole patterns, equipment, and procedures?
We couldn't find a specification for undersealing industrial floors. But there are several good sources of information related to highway applications that would help you to write a specification. Here are three good sources: Cementitious Grouts and Grouting, Engineering Bulletin EB111.01T, Portland Cement Association, 5420 Old Orchard Rd., Skokie, IL 60077, 1990. Pavement Stabilization by Undersealing, ChemGrout Inc., P.O. Box 1140, LaGrange Park, IL 60525, 1985. Cement Grout Subsealing and Slabjacking of Concrete Pavements, IS212P, Portland Cement Association, 5420 Old Orchard Rd., Skokie, IL 60077, 1982.
