Stone Infill

In the process of conserving a gravestone, it may become necessary to add infill, to replace or crumbling stone. Infill refers to a mix formulated to fill a void or gap, in masonry, and ideally to have it blend in with the rest of the stone, or substrate. Infill of various types has been used since antiquities to restore damaged sculpture, gravestones or masonry structures.
