1. In the process of impregnating large volumes of concrete in the field, such as roadbeds, walkways, and bridge decks, with a polymer or a monomer for in situ polymerization wherein it is necessary to dry said concrete prior to impregnation, the improvement of employing a temperature measurement to determine moisture content which comprises(1) determining the appropriate dryness for impregnation of said concrete by heating said concrete until a temperature-indicating device below the surface and within the concrete at the desired depth of monomer penetration indicates a minimum temperature of about 230°

  • F., and(2) impregnating the concrete to the desired depth with said polymer or monomer composition.
