In this special edition of Rock Solid, Dean and Derek are drawn to the bright neon lights of Las Vegas for the World of Concrete 2009. With over 1,700 exhibitors, Dean and Derek learn about the latest innovations in concrete materials, equipment and technology. They'll get their hands dirty by demonstrating new products and testing out new machinery. They even run into Cool Tools host Chris Grundy who eagerly shows them one of his favorite time saving tools. From the coolest concrete pavers to the greatest concrete mixers, Dean and Derek can't get enough of this stuff! As the ONLY annual and international construction show for concrete and masonry - this show is perfect for our two concrete-loving masons!
