On June 2, 2014, the Delaware Department of Transportation closed a bridge on I–495 that was leaning and out of plumb.[Editor] The Delaware Department of Transportation (DelDOT) had a major problem on their hands after a bridge on I-495 was leaning…one side of the bridge was 18 inches higher than the other.  The culprit?  A pile of fill adjacent to the bridge was loading soft soils beneath.  So what do you do about it?  In this contributed article by Dennis M. O’Shea, bridge engineer in the FHWA Delaware Division Office, he describes the problems faced by DelDOT, the causes, and how they fixed it.  The article originally appeared in Public Roads Magazine, and is republished here with permission.

Pepsi Bottling Plant Uses TerraThane Geotechnical Polyurethane Foam by NCFI to Save Spillage and Lost Product

TTPepsi1MOUNT AIRY, NC—When the ground inevitably shifts and erodes beneath concrete slab floors of factories and warehouses like the Pepsi Bottling Group facility in Nashville, TN, the slabs become uneven and the joints become mini-speed bumps. Drivers of forklifts will tell you it makes for a bumpy ride as they transport pallets of Pepsi and other beverages across the facility. It also means the quality of the beverage can be affected by the jostling.

 

Pepsi called in specialist Eddie Bolton and his company, Mid-South Concrete Leveling, Milan, TN, to help save “The Choice of a New Generation” for the millions served by the plant.

“They initially thought the concrete slabs needed lifting, which takes a good deal of time and much more work and product,” says Bolton. “But when we got there we found we could do what is called joint stabilization and not have to level the entire slabs.” [Editor] Click through for the rest of the press release.
