The world was different in 1917 when L.D. Bailey and D.W. Longfellow founded The Cretex Companies, Inc. (Cretex). The migration from a rural to an urban society was creating an infrastructure need never experienced in our history. The vision of the founders was to fill that need by supplying quality concrete pipe products to Minnesota communities. Over the decades, Cretex has changed and grown with the times. Through diversification the company has thrived despite the dramatic cultural changes our country has experienced. All without losing sight of the founders vision—to supply a quality product to our customers.
