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 process that has resulted in a full line of patented open ended concrete masonry units branded as ProBlock.
Modified "A"
Knock-out "H"
The ProBlock Masonry Wall System is a wholly new concept developed for productivity, safety, energy performance and profitability
Benefits
Reduced project cost and faster project schedule
ASTM C90 compliant
High thermal R-values without the cost premium of other high R-value masonry wall systems
Open-end design allows masons to lay around vertical rebar and avoid overhead lifting
Unique Features
26%+ lighter than other CMU's of the same material mix, making it easier to handle and quicker to install
Ability to go around rebar instead of up and over eliminates or reduces rebar splicing and therefore the amount of steel required for the project
Balanced center of gravity is located properly "in the center web" of the block for ease of handling
