Cementitious grout (2)

Grouts for crack and void concrete repairs must be selected to suit type, location, condition and size of crack. For testing of compressive strength and other properties as part of quality control. BS 8298 recommends a 1:1 cement:sand mix for grouting fixings for natural stone cladding in place. The use of proprietary epoxy and modified polymer mixes is on the increase, particularly for stronger stones.
