Concrete Tombstones, The "Poor Cousins" of Matzevot Typology
by Samuel D. Gruber
I first began thinking of the use of concrete for Jewish tombstones last week while watching, at a conference on Jewish Cemeteries in Europe, the new film Testimonies Carved in Stone about the Jewish cemetery in Alba Iulia, Romania. The narrator mentioned the use of concrete for gravestones for poor people, because of the low cost of the material. instead of carving an inscription, a short epitaph could be impressed upon the concrete while it was still drying. When I visited the Jewish cemetery in my ancestral home of Kalvaria a few days later, I immediately saw the concrete stones everywhere (albeit this is a much reduced cemetery, stones from the older parts are no longer visible).
Usually when working on issues of Jewish cemetery documentation and preservation talk of concrete, cement, cast stone or other similar composite materials comes up when discuss methods of repair - since the inappropriate use of concrete to patch stones can frequently cause more damage.
In fact, a closer consideration of the material reveals that concrete was not uncommon as a primary materials for Jewish gravestones in the decades before the Holocaust. Just as the new material became a favorite in industrial and commercial (and even some residential) building, so too, it became increasingly accepted for use in the sacred setting of Jewish cemetery.
Discussion of concrete gravestone has probably been neglected for several reasons. It is a relatively new material, so older and often more picturesque cemeteries do not have examples. As presentations at the conference demonstrated, most scholarship related to Jewish gravestones looks at examples from the pre-modern period. But another reason is that concrete can often only be easily differentiate from stone from close up examination of the examples. Photographs, especially when not close-up details, often make the concrete matzevot look like traditional stone. There are a few give-away signs. Concrete stones seem to date mostly from the 1920s and 1930s (though more examples may expand this range to earlier years). Like bricks and other molded objects, concrete gravestones tend to have few raised features, and usually have consistent thickness and smooth edges. Decoration is often impressed in patterns from pre-made forms (just like bread-stamps), and so is often repeated on multiple stones. Many broken "stones" at Kalvaria show that iron reinforcement rods were often (always) installed to stiffen the stone which had to stand for years in a upright position.
Today, metal detectors could be used to ascertain the use of metal inserts. Corrosion of these through water infiltration can cause deterioration and eventual collapse of the surrounding concrete. Thus, the breakage of many concrete matzevot may be due to natural causes as well as to vandalism.
Concrete was also used in Chridtian burials, and there are many examples in the United States contemporary with those at Kalvaria. Conservationist Stephanie Hoagland, a Senior Associate and Architectural Conservator with Jablonski Building Conservation Inc., has written about some of these:
She says that
"Many of these markers were constructed in the same way as cast stone or a concrete sidewalk would have been laid. A single or multiple layers of concrete were poured in lifts and a slurry coat applied on top, into which the inscription was written. Note the layers clearly visible in the side views of these two markers...If the maker was familiar with concrete or cast stone, they would have been aware that concrete markers such as these require some form of internal reinforcement for strength. Unfortunately, the use of ferrous metal often meant that the marker has been damaged by the very thing added to make it durable. Many of the markers do not meet the minimum depth requirement for reinforcement, which has led to its corrosion. But this damage has provided us with the chance to see the variety of materials used for reinforcement, including bent rods, smooth rods, twisted rods, flat bars, pipes and wires"
