Bayer Hazardous Waste Diked Area
Owner: Bayer Polymers LLC
System: Hehr 1340
PolySpec Thiokol 2378 Plus
Area: 120 SF Coating
350 LF Crack Repair
Completed: December 2003
Mobile crews removed the existing coating within the failed area and replaced it with a 30 mil coat of the original Hehr 1340 material. The cracks were lightly abraded, PolySpec T-415 primer applied and a 12” band of PolySpec Thiokol 2378 Plus installed as a base coat and a 6” strip of engineering fabric installed in the base coat. The base and fabric were then covered with a topcoat of PolySpec Thiokol 23678 Plus, providing a reinforced, flexible, positive seal over the cracks.
The work was completed quickly without use of any electric tools as such tools were prohibited within this area.
