Rubble stone is irregularly-sized, rough stone which can be used for a variety of purposes, including rubble walls, fill, and stepping stones. The spray foam people say, of course, "just spray foam the walls" which will ostensibly keep moisture and cold out. The walls are thoroughly wetted to limit suction and polymer modified cement-based grout is injected via a long nozzle to fill the bore in each stone before a helical bar is pushed into the unset grout. There are two types of preparation for stone used in housebuilding: rough uncut 'rubble' stone; and dressed cut 'ashlar' stone.

The sack masonry is born as an evolution of embankment covered with boards, stones or bricks. The mechanism for this is that over the years the water penetration washes the fine material out of the core infill, allowing the fine materials and the loose infill to drop down the wall.
