Structural Testing Update

The National Concrete Masonry Association (NCMA) has recently re-tested both the System 12 and System 8 individual block units. These new test results continue to show that different block plants that have manufactured Omni Block easily pass the ASTM C-140 test minimums and meet the ASTM C-90 test criteria. The pages are listed here but can also be found at https://www.omniblock.com/astm-c-140-standard-test-methods-for-sampling-and-testing/ on this site.
