MOUNT AIRY, NC—Concrete Jack, Inc. of Williamsburg, VA, a company specializing in concrete leveling and foundation repair along the Eastern Seaboard and the South, used TerraThane Geotechnical Foam system to help save the parking lot of a Wake Forest, NC auto repair business.
"Parking lots are notorious for sinking from failed storm water structures," says Kirk Roberts, division manager for Concrete Jack. "Water causes erosion around the structures, voids form, voids enlarge over time then the parking lot just collapses. Sinkholes can shut down businesses and cause damage to customer vehicles."
Roberts says the municipality's public works department determined the joints between the four foot sticks of pipe had been improperly gasketed, or seated, during installation. The pipe saw a continuous flow from a small stream entering at an end wall and discharging into a box culvert crossing a public street. The drop inlet at the downstream junction between the RCP culvert and box culvert also failed at the 18-inch RCP culvert feeding it, which had been repaired multiple times using open trench excavation.

Founders Included Chemist from Manhattan Project, Pioneer of Urethanes, and Charlotte-Based Cotton Company
MOUNT AIRY, NC—NCFI Polyurethanes, an international manufacturer of rigid and flexible polyurethane foams turns 50 this year. The Mount Airy-based company got its start in 1964 as North Carolina Foam Industries through a partnership between Dr. Harris W. "Ace" Bradley, who had worked on the Manhattan Project during WWII and with Dupont in discovering and pioneering urethanes in the 1950s, and the Barnhardt family, founders of the Barnhardt Manufacturing Company.

Hawthorne, NJ (May 28, 2014): DFI announces the formation of a new, 16th technical committee focusing on site investigation for deep foundation design and construction.
The Subsurface Characterization for Deep Foundations Committee was formed to increase awareness of the importance of complete and competent site investigation in deep foundation practices. The specific goals of the committee will be defined by the committee members, however, initially the committee will discuss and define subsurface characterization needs from the point of view of the entire geotechnical/foundation industry. This will facilitate getting correct and comprehensive information to the end users (designers and contractors) and minimize change condition issues/debates. The committee will liaise with associated committees from other organizations and agencies to broaden the discussion within the engineering community. The objective is to find the common ground that allows the entire geotechnical industry and all project participants to minimize disagreement during construction, align expectations, and improve communication and understanding among related parties.

I know this video made the rounds by email and on Geoengineer a while back, but I haven't posted it here. It shows a novel way of installing piles in softer soil. Those guys have some nice rhythm! Happy Friday.

Keynetix are delighted to have been offered the opportunity to be a regular contributor to the Geotechnical Academy starting in June 2014.
The Geotechnical Academy is a collaboration between Equipe Group and Geotechnical Engineering Ltd, providing fundamental technical and commercial training to aspiring geo-professionals, helping them to apply their theoretical and technical understanding in the practical and commercial world.
The training experience is different from other more traditional offerings, in that it will take a group of delegates and their sponsors on a journey over a whole year, to greater knowledge and appreciation of their subject.
Roger Chandler of Keynetix will be taking part in the training sessions that will form part of this fantastic academy. Here he will be raising awareness in the industry of the importance of Geotechnical Data Management, AGS, BIM and the new BS 8574.
“The Geotechnical Academy is a great opportunity for both new and experienced engineers and it is great to be able to contribute to one of the modules.” says Roger “Good geotechnical data management is vital in today’s workplace and I find teaching this to engineers very enjoyable and rewarding. I’m looking forward to helping engineers experience some exciting light bulb moments over the coming months and then giving them practical advice on how to make better use of their time and geotechnical data.”
Roger comes from a Geotechnical background and has been an active member of the AGS Data Management Committee since 1997, a member of DIGGS Cone SIG since 2005 and was the co-author of AGSM.
Liz Withington of The Geotechnical Academy says “This is on-the-ground practical development for early stage career geo-professionals. The Geotechnical Academy is a partnership between Geotechnical Engineering Ltd & Equipe Training, providing unique, high quality vocational geotechnical CPD development for early career engineering professionals. We are delighted to have Roger Chandler from Keynetix as a regular contributor. Rogers’s innovative approach to geotechnical data management demonstrates The Geotechnical Academy’s commitment to challenging young geo-professionals in to stimulating change within the industry“
Attendees of the academy will gain knowledge, join in practical demonstrations of equipment and techniques, take part in discussion about a wide variety of technical and commercial topics relevant to their work and hopefully have a thoroughly enjoyable experience to inspire them into the future! All training days will be eligible for CPD certification.
A massive mudslide approximately 1 mile by 3 miles by 250 feet deep has occured in Western Colorado over the Memorial Day weekend. There are reports that 3 men from the nearby Collbran/Mesa area are missing. According to the Forbes article, the estimates of the size would make it three times the size of the catastrophic Oso landslide in Washington. [Source: Forbes via @CanGeotechJournal.

This is a different perspective on landslides than what I usually blog about on GeoPrac. This banking and insurance website blog post discusses what should and shouldn't be covered on a car owner's insurance policy. Several cars parked along the road were damaged after a retaining wall / slope failure in Baltimore last month. [Source: Read the blog post at Bankrate, Inc.. Image: CBS Baltimore]
