Jan. 2009 - Our Warsaw, KY plant has just received a Platinum level safety award from the NPCA. This award is given to plants with zero OSHA recordable injuries in 2008 and over 40,000 hours worked. The award will be presented at The Precast Show in Houston on Feb 21. Congratulations to all employees at our Warsaw, KY plant!

Nov. 2008 - Our Medium Vehicle trench design has been refined and the drive over rating has been upgraded from 7,000 GVW to 9,000 GVW - at the same price.
New orders for our Medium Vehicle trench will automatically get the 9,000 GVW rating.

Sept. 2007 - We have added a standard 48" deep trench to our line of extra deep HS20 road crossing trenches. These are available in widths up to 96". See page 16 of our Catalog.
