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.
