Breaking the Guinness World Record for the Largest Continuous Mat Pour

Starting at 4:47 p.m. on Saturday, February 15, 2014, Conco broke the Guinness World Record for the largest continuous mat pour in 18 ½ hours (1 ½ hours under the projected time).  To verify the event, there was an official Guinness World Records adjudicator on-site.  The mat pour was for the new Wilshire Grand Center that is being constructed in downtown Los Angeles and is slated to become the tallest building in the U.S. west of the Mississippi.  Read more…
