Industry Development in the United States The 50-year old U.S. concrete masonry block industry expanded with the post-WWII housing boom. The demand for masonry block, however, contracted in the early 1960’s resulting in some block manufacturers seeking other, more profitable products such as concrete pavers. The start began in 1975 when Don Lampus of R.I. Lampus Company near Pittsburgh, PA, and Darwin Ross of Balcon in Baltimore, MD, met Mr. Bryant who was producing pavers in Barrie. Mr. Lampus and Mr. Ross traveled to Germany and toured German paver manufacturing plants, paving projects, and met with production equipment suppliers. Most paver production equipment was from Knauer, Zenith, Hess and Schlosser. Production equipment was either a traveler or stationary multi-layer equipment. In 1975, the R.I. Lampus Company purchased a Knauer traveler machine. Balcon elected to produce pavers on a masonry block production machine and later purchased a Knauer machine. In addition, Pavers by Ideal in Waltham, MA, began manufacturing concrete pavers in 1975 on a masonry block machine and with refinements to this equipment were able to achieve high strength units. After the Uni-Group, other licensors brought various paver shapes to the U.S. and Canadian market. These include London, England-based McCauley Corporation, Ltd. with inventions from architect Michael Glickman including the G-block. Symrah Licensing promoted the tile-like Symetry pattern developed by Roberta Hair from Cincinnati, Ohio. Tile designer and artist Bonnie Tomek from San Francisco also developed paver designs. Germany’s SF Kooperation managed by Helga Piro (based in Canada) promoted interlocking paver shapes, early permeable paver designs, and interlocking paving slabs. First Industry Association Mr. Bryant and Mr. von Langsdorff traveled to the U.S. in 1975 to connect with several paver producers who had also invested in paver manufacturing. Mr. Bryant and Mr. von Langsdorff promoted licensing of Uni-stone (and later other patented paver shapes). From that effort, the Uni-Group was formed in 1975 and grew to include the following companies: Acker Stone, Corona, CA Anchor Concrete, NJ Angelus Block, Stanton, CA Balcon, Baltimore, MD Barkman Concrete, Winnipeg, MB Borgert Products, St. Joseph, MN Browns Concrete, Sudbury, ON Dinon Precast, New Orleans, LA Expocrete, Edmonton, AB Hokanson Block, South Sacramento, CA Interlock, Hampton, VA Interpave, Cincinnati, OH Kirchner Block & Brick, St. Louis, MO Muller Supply, Lodi and Banning, CA Mutual Materials, Bellevue, WA Paver Systems, West Palm Beach, FL Pavers by Ideal, Waltham, MA Permacon, Ville d’Anjou, QC R.I. Lampus, Pittsburgh, PA Reading Rock, Cincinnati, OH Unilock, Georgetown, ON Weldon’s Concrete, Regina, SK Westcon, Langley, BC Willamette-Graystone, Portland, OR Pavestone, Dallas, TX Besides manufacturing patented and licensed products, the Uni-Group licensees funded national advertising, issued printed case studies, participated in trade shows, and supported research. They also received information on best installation practices from Germany. 1 0 • I C P I C O M M E M O R AT I V E P U B L I C AT I O N
