Abstract
A grouting composition for sealing structures to inhibit water leakage therethrough and for stabilizing soil is provided. The composition is provided as a two-part system. Part A is an aqueous solution of a hydrophililc, water soluble prepolymer having a polyether backbone and terminal active olefinic groups, the olefinic groups being connected to the polyether backbone by linking groups selected from --NH--, --CONH--, --OCONH--, and --NHCONH--, and tertiary amine catalyst. Part B is an aqueous solution of a initiator. Parts A and B are mixed and react to form a gel.
