Omni Block has been throughly tested through the years. The most convincing “test” is that as of August 2017 there are over 1300 buildings constructed with Omni Block in 29 states, Mexico, Canada and Saudi Arabia. There are commercial, residential and institutional buildings all performing as advertised.

The links below provide testing results. Each manufacturer of the block should provide current structural tests.
