The post-World War II era saw the Netherlands facing a coal shortage that hindered the production of clay bricks for construction. As a solution, concrete paving units were developed, quickly gaining popularity in Germany where both Dutch and German companies innovated high-efficiency manufacturing equipment in the 1960s. This technology spread across various countries, including England, Australia, and South Africa, with Germany now producing over one billion square feet of concrete pavers annually. Today, interlocking concrete pavement is the best paving system worldwide, celebrated for its flexibility and strength.
