Barrier Corp. was purchased by The Krez Group in 1981 from a small company in South Bend, Ind., to add services for providing Lightweight Insulating Concrete Roof Decks to our customers.

Soon, after moving to Morton Grove, the company added Tectum Wood Fiber Roof Decks, followed by Floor Leveling, Acoustical and Radiant Floor products, as well as Cementitious Floor Overlayments.  

Those additions led to expansions into Concrete Topping, Epoxy Floor Systems, Concrete Staining, Concrete Stamping and Promenade Roof Systems. Those were followed by new product lines in Structural Concrete and Concrete Repair. Most recently, Traffic Coatings were added to complete the line of products we currently offered to our diverse customer base.
