New chemical grouts are now available to repair sewer leaks, control groundwater movement, and stabilize incompetent soils. Some of these grouts came into being only after the American manufacturer of the most commonly used grout, acrylamide, stopped selling the product. The article describes the four basic chemical grout families (acrylamide, acrylate, urethane, and polyacrylamide), how they work, and how to select the right grout for the application. Photos illustrate some representative grouting jobs, and a special section devoted to the toxicity problems associated with acrylamide grout.
