Bring CarbonBuilt into your local plants.

CarbonBuilt low-carbon-concrete CMUs loaded onto Blair Block truck

Together, we can build a groundswell. We can turn the global concrete industry into a global concrete sink. We can store carbon for good.


Let concrete block producers in your area know you want to specify ultra-low carbon concrete CMUs for future projects.

Sign up below and we’ll send you a letter of support along with a list of concrete plants in your area so you can help urge them to bring CarbonBuilt into their plants.

NOTE: This is not a pre-commitment to buy or an offtake agreement — it’s simply a non-binding support letter to let block producers know you’re interested.
