Grain Bin Settlement Problems Common to Concrete Foundations Solved with NCFI’s Geotechnical Polyurethane Foam Technology PDF Print E-mail

Grain bin at a Williamsburg, Virgina poultry processing facility that had foundation settlement issuesNew Solution Saves Money and Time Preventing Loss of Grain and Equipment Damage

MOUNT AIRY, NC—Soil consolidation and settlement happens. It’s a fact of farm life. Secondary consolidation slowly forces water out of the spaces between soil particles. As this happens, soil particles move close together and settling occurs. Floors drop and become uneven. Newer grain silos and bins are using concrete floors instead of metal, and as secondary consolidation occurs beneath them, depressed or “settled” areas, form within the bin. Grain accumulates in the depressed areas, but cannot be retrieved by the bin sweeper. In fact, the sweeper, a kind of auger that transports grain up from the floor, can become damaged from prolonged exposure to the uneven floor.

This is exactly what Kirk Roberts of CJGeo, a Williamsburg, Virginia-based commercial foundation repair and geotechnical contractor, found when he got the job to repair the foundation of a massive 106-foot diameter grain bin at a poultry processing facility on the Eastern Shore of Maryland. “Once they removed the hundreds of thousands of bushels of grain, we found the floor had dropped some three inches in one section of the bin leaving a large pocket of grain out of reach of the bin sweeper.”

DFI Announces the 2016 Outstanding Project Award Winner PDF Print E-mail

hir120-1Hawthorne, NJ (July 7, 2016): The Deep Foundations Institute (DFI) is proud to announce that Hayward Baker is the 2016 Outstanding Project Award (OPA) winner for the design and construction of foundations at the International Market Place in Waikiki Beach, Honolulu, Hawaii.

The award will be presented at the DFI International Conference on Deep Foundations, Seepage Control and Remediation (41st Annual Conference) in New York City, October 12-15, 2016.

Opening in August 2016, the International Market Place, a well-known retail, dining and entertainment destination, has undergone a complete revitalization. Hayward Baker was the foundation contractor for the construction of a new 80,000 sq ft Saks Fifth Avenue anchor store, a 7-story parking garage and two 3-story retail structures located on a 6-acre site in a heavily congested area of Waikiki Beach. The company installed 544 micropiles to depths of up to 315 ft to support the structural loads. Difficult site geological conditions and cultural restrictions presented significant challenges for the design and construction of the foundations. The project site was located within the boundaries of an ancestral Hawaiian burial ground that required pre-excavation prior to any installation of below grade improvements. Additionally, two existing historic banyan trees on the site had to remain in place and not be trimmed for equipment access.

Historic Pennsylvania Tunnel Reopens with Help From NCFI’s TerraThane Polyurethane Foam PDF Print E-mail

Pinkerton TunnelMOUNT AIRY, NC—A $2 million tunnel construction project on the Great Alleghany Passage (GAP) is reopened to the public with help from a geotechnical polyurethane foam called TerraThane, by US company, NCFI Polyurethanes.

The GAP rail-trail is 150 miles of hiking and biking between Cumberland, Md, and Pittsburgh, Pa. created along the former railway line. In Cumberland, the GAP joins the C&O Canal Towpath, creating a continuous 335-mile long trail experience all the way to Washington, DC. It’s become a favorite biking destination for people from around the Mid-Atlantic states. One of its main tunnels, the Pinkerton Tunnel, an 849-foot former Western Maryland Railway tunnel, has been closed since 1975 due to erosion and unstable conditions. The Allegheny Trail Alliance, the organization that built and now maintains the 150-mile GAP, and the Somerset County Rails-to-Trails Association (SCRTA), wanted the tunnel reopened and helped fund the project.

Nicholson Completes Emergency Work on Indiana's I-65 PDF Print E-mail

Nicholson Construction stabilizes pier on I-65 using micropiles and low-mobility groutingPITTSBURGH, PA – Nicholson Construction recently completed emergency repair work to an unstable pier supporting a bridge on INDOT’s Interstate 65. These repairs enabled a 37-mile section of the highway’s northbound lanes to be reopened after a four-week closure.

The highway was in the process of being rehabilitated and widened when the pier was damaged by steel piles driven into the water tight ground below it. The pier began to settle and eventually rotated ten inches.

Nicholson developed a design-build solution that used micropiles to transfer the loads to more stable soils and low-mobility grouting to fill voids and densify the upper subsurface layer.

United States of America Department of Transportation New Initiative Modeled After Longstanding Bridge Program

WASHINGTON –The U.S. Department of Transportation’s Federal Highway Administration (FHWA) today published the final rule for national tunnel inspection standards that will serve as the foundation of the nation’s first standardized tunnel inspection program. It will be modeled after the FHWA’s successful bridge program established nearly a half-century ago to ensure the safety of the nation’s bridges.

“This important step to keep our nation’s tunnels safe for the traveling public is unprecedented,” said U.S. Transportation Secretary Anthony Foxx. “Establishing national standards will help us maintain a high level of quality and uniformity in tunnel inspections nationwide.”

Nortex and TerraThane Stabilize Houston Area Highways PDF Print E-mail

Houston’s Highways, Some of Busiest in Nation, Use Innovative TerraThane Polyurethane Foam Technology to Repair Bad Bridge Approaches, Uneven Joints, and Roadway Depressions.

Nortex employees stabilizing Houston area freeway with TerraThane Polyurethane Foam

MOUNT AIRY, NC—Highways around Houston, TX, known as one the nation’s worst cities for traffic behind Los Angeles, D.C., and Atlanta, need constant repair, but can’t be closed while the work is done. Nortex Concrete Lift and Stabilization, Inc., a Ft. Worth, TX company, recently completed a whirlwind repair project on one of the city’s busiest corridors in the NE quadrant where I-10, 610 Loop, I-59, and I-69 feed millions of cars daily to, from, and around Harris County.

Normal groundwater erosion beneath the highways causes the concrete highway slabs to drop, roadway depressions, uneven bridge approaches, and uneven joints that make driving bumpy and uncomfortable, dangerous, and causes severe wear and tear on automobiles.

To make the repairs, the Texas Department of Transportation, TXDOT, brought in Nortex. The company carefully planned out the repairs for the half million pound project, and sent out four crews each with it’s own box truck rig to use a relatively new technology called “foamjacking.” Foamjacking uses high-density polyurethane foam to fill the subterranean voids, and lift the concrete slabs to proper level. “We’ve been lifting and stabilizing roadways with polyurethane foam since we got into the business back in 2003,” says Casey Derosa, asst. gen. mgr. of Nortex. “It’s a far superior method versus the old way of mudjacking.” Mudjacking is a ubiquitous term for a mix of mud, sand, cement, crushed limestone, and water hydraulically pumped into large holes drilled into the concrete slabs to fill voids and level the slabs. Mudjacking uses more and much larger equipment, and requires larger holes to be drilled. It typically requires the roadway to be closed much longer than foamjacking, and takes more time to clean up.
