I’ve never thought too much about this, I guess I’m still waiting for my first geotechnical assignment in Hawaii! But if you bring soil samples into the continental USA, they must go through a heat treatment at their port of entry. In the latest GeoComp Corporation newsletter, Gary Torosian from GeoTesting Express, GeoComp’s lab testing arm, describes how their firm’s certification with the U.S. Department of Agriculture allows them to accept soil samples without the required heat treatment. They can receive, and test the samples and then upon completion of the testing, they heat treat the soil, sample containers and any effluent generated from the testing process to safely dispose of any potentially harmful organisms. Something to keep in mind for those cushy projects in Hawaii or the US Virgin Islands or something. (Photo by Eric K. Veland on Flickr)
Pepsi Bottling Plant Uses TerraThane Geotechnical Polyurethane Foam by NCFI to Save Spillage and Lost Product
MOUNT 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.

A New Mexico mountain resort recently unveiled their new fitness complex which featured a large indoor swimming pool and 32 person spa. Built on the side of a mountain, on side of the spa structure sits on top of approximately 12.0’ of fill material. When the spa and portions of the deck began to show telltale signs of settlement, the spa was drained and taken out of service, and an investigation was conducted. This investigation revealed a large plumbing leak which had occurred under the pool/spa deck, causing compaction and consolidation of the supporting fill materials. The general contractor on the job broke out a section of the pool deck to make the plumbing repair, and then turned to URETEK ICR for the remediation of the settlement issues.
Management was pleased that the process meant no disruption for their guests. URETEK’s solution was less than 20% of the cost of replacement of the structure.

[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.
