Zusammenfassung:	This invention relates to a one-step process for rapidly repairing structures. The process uses a binder comprising a polyisocyanate-terminated pre-polymer containing a divalent metal catalyst, and preferably a tertiary amine catalyst, which cures in the presence of moisture. L'invention concerne un procédé en une étape pour la réparation rapide de structures. Ce procédé fait appel à un liant comprenant un prépolymère à terminaison polyisocyanate contenant un catalyseur de métal divalent, de préférence un catalyseur d'amine tertiaire, qui durcit en présence d'humidité.
