Concrete block foundation became popular after 1900, when Harmon Palmer patented the first cast-iron hollow block machine. His invention allowed two men to produce eighty to one hundred fire-resistant, low-maintenance, low-cost (compared to stone) blocks in a day. These concrete blocks were used both for foundations and for walls. Until the 1930s, the most popular face designs were rock face (shown here) and panel face. (Adrian, 2023)
