Veneered Stone Walls

Most stonework today consists of a non-structural veneer of stone against a structural wall of concrete or cinderblock. Concrete consists of Portland cement mixed with sand, gravel, and water. The larger particles of gravel interlock like little fingers to make the concrete resistant to cracking.
The steel reinforcing bar can be added to serve as much longer “fingers” to make a wall that is very resistant to cracking. Concrete is a fast and relatively inexpensive way to put up a structural wall, so few people take the time for labor-intensive traditional mortared stone walls any more.
