Mafia Block


What is Mafia Block?

Definition of Mafia Block in Construction
Term used to describe the concrete blocks that are made by most concrete supply companies out of the washouts from their concrete mixers.

Years ago, these blocks were only made as a place to put the concrete, and if they were needed for storage bin walls or barricades, t hey were utilized. The development of the concrete barrier has changed this and many concrete suppliers manufacture these blocks in different profiles to be used on highway projects or retaining walls. The term mafia, is a self explained reference due to the abundance of Italian American concrete suppliers in the Northeast, particularly New York City.
