Calsil 972

Calsil 972 is a puzzolanic injection and filling mortar for cracks and cavities. This stress relieved injection glue is particularly suitable for historical monuments. Calsil restores low strength natural masonry and fills cavities in rocks or concrete securely. The excellent pumpability without sedimentation and the excellent spread even into fine pores of 0,5 mm, make Calsil 972 superior to any cement sand injection.
