Standard CMU - Jandris Block
Most units available in single and double bullnose. All load bearing units shall conform to ASTM C-90. All Normal Weight aggregates shall conform to ASTM C-33. All Light Weight aggregates shall conform to ASTM C-331. All Portland Cements shall conform to ASTM C-150.
Scored masonry units are available in all shapes and sizes desired. Multiple scores can be added if needed. This versatile unit serves many purposes on the job site. Sawing is minimized as the units will surround re-bars,conduit drains and act as a chase for utilities, as well as an alternative to beam lintel applications.
