A Labor Saving Revolution in the Concrete Masonry Market

ProBlock is a patented concrete masonry unit developed and marketed by Johnson Concrete Company. It is the final result of close collaboration between Johnson Concrete’s engineers and production team, block masons and architects. That collaboration yielded the idea to redesign the standard "knock-out" or "A" block to be more efficient to manufacture by the producers and put in place by the masons. 

The result of 6 years of research, design development, and marketing is a unique concrete masonry unit with increased energy efficiency, increased factor of safety, and increased productivity in both the manufacture and installation (by mason) while being lighter in weight.
