HISTORY

Since being founded in 1955, Tilcon Delaware has been providing high-quality paving and construction materials to the Delmarva Peninsula. In 1996, Tilcon became a member of Oldcastle Materials, Inc. and eventually formed the Mid-Atlantic Group of Oldcastle along with Pennsy Supply, Slusser Brothers and Pioneer Concrete.  
Pioneer Concrete has a long history dating back to 1934 when Alessandro Petrillo, an Italian immigrant, came to America and founded A. Petrillo & Sons Concrete. In 1993, Michael and Bill Petrillo, the fourth generation of Petrillo’s in the concrete business, formed Pioneer Concrete, which became a member of Oldcastle Materials, Inc. in 2006.
Today, Pioneer Concrete is the largest ready-mix producer and concrete pumping service in Delaware and surrounding regions. Our mission continues to be to consistently provide excellent service and quality products to our concrete customers in a highly professional manner.
On May 12, 2009, Pioneer Concrete and Tilcon Delaware merged to become Pioneer Materials.  Pioneer Materials  is a division of Oldcastle Materials which is the leading vertical integrated supplier of aggregates, asphalt, ready-mix concrete and paving services in the United States and is one of four divisions of CRH plc, in the international building materials group.
