A Labor Saving Revolution in the Concrete Masonry Market

ProBlock is a patented concrete masonry unit developed and marketed by Johnson Concrete Products. 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 and install.

The result of 6 years of research, design development, and marketing is a unique concrete masonry unit that allows for increased energy efficiency, improved safety, reduced installation cost and faster project schedules.
