Abstract

The invention relates to a method of stabilizing the bonding agent gelation time in the consolidation of a geological formation in the presence of one or more catalytically active substances, in which method a bonding agent is infiltrated into the formation, a portion of the infiltrated bonding agent is optionally expelled by flushing with a gas or a liquid, and the bonding agent remaining in the formation is cured. the bonding agent comprises a mixture of a) a heterocondensate, obtainable by hydrolysis and condensation of at least one hydrolyzable silicon compound and at least one metal, phosphorus or boron compound, the metal being selected from Al, Ge, Sn, Pb, Ti, Mg, Li, V, Nb, Ta, Zr and Hf, B) at least one organic polymerizable monomer or oligomer comprising a C-C double bond, and C) at least one thermal polymerization initiator without peroxide function.
