A Labor Saving Revolution in the Concrete Masonry MarketProBlock 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.It all started when...The ASTM C90 standard changed from requiring 2.25 in/ft minimum equivalent web thickness to requiring 6.5 in2/ft2 normalized web area in standard concrete masonry units. What followed was a 6 year design genesis that has resulted in a full line of concrete masonry units that are a patented redesign of an A-shaped, open ended CMU. The design of the original ProBlock along with the logo, marketing literature, and even the website has matured along with the engineering behind it.The ProBlock masonry wall system is a wholly new concept developed for productivity, safety, energy performance and profitability. BenefitsImproved mason productivityDecreased risk in job-site related injuries Reduced project cost and schedulingSavings on rebar and labor through reduced lappingASTM C90 ComplaintsHigh thermal R Values without the cost premium of other masonry wall system Unique Features26%+ lighter than other CMU's of the same material mix, making it easier to handle and quicker to install.Open-end design allows masons to lay around vertical rebar , utility runs and reduce or avoid overhead lifting. Reduce rebar splicing and the amount of steel required for the project.Balanced center Block
