Topic Summary
The labor for installation of split-faced concrete blocks costs more, as installing this block takes additional skill and effort. Split-faced units can also be manufactured with ribs or scores to provide strong vertical lines in the finished wall. Rough textures, like those available with split-faced units, are often used in areas prone to graffiti, as the texture tends to discourage vandals.
Concrete block plants exist in many areas and most of them will create split-faced or half-block CMUs. Split-faced CMU construction offers durability, stability, weather resistance, and material inertness in addition to its stone-like appeal. Areas where damage by wind and water are an issue, such as coastal regions, benefit from the strength provided by CMU construction. Additionally, all CMU construction is susceptible to water penetration and has a low tolerance to freeze/thaw cycles.
