Abstract

1485892 Stabilizing rock formations BERGWERKSVERBAND GmbH 15 Oct 1975 [15 Oct 1974] 42180/75 Heading E1F Water-bearing geological formations are sealed and consolidated by the injection, into cavities in the formation, of a freshly prepared mixture of a polyisocyanate, a polyol, an accelerator, and a foam stabilizer; the mixture is allowed to absorb water from the formation to produce a foam, which then sets.
