Abstrakt

The grouting of historic masonry with degraded binders or masonry units, masonry with insufficient load-bearing capacity, masonry damaged by cracks, with a high void content and cavities and multi-leaf masonry is one of the rehabilitation methods of masonry frequently applied in practice, restoring its integrity and increasing its load-bearing capacity.
