Method of protecting structures which are constructed underground and contain cement as binding agent

摘要

Structures and/or structural parts which are constructed underground (in situ) and are made of construction materials which contain cement as binding agent are to be protected against substances which damage the cement. So that such structures which cannot be specially insulated are protected from destruction through attack by chemical action, agents neutralising the substances damaging the cement are fed into the earth areas directly adjacent to the structures.
