Method of coating geological formations as well as air- and fire barriers

摘要

Coating of geological formations as well as air- and fire barriers is performed by providing aqueous rubber or rubber-like dispersions and spraying the dispersions via separate conduits simultaneously with a dry hydraulic binding medium, by a pressure air onto an object to be coated. An inert filling material can be added to the hydraulic binding medium, and a tenside can be added to the dispersions.
