Pipeline Contractor Uses Advanced Technology Product in Challenging Marcellus Shale Region: Saves Money, Reduces Labor Costs and Erosion, and Protects Pipeline

MOUNT AIRY, NC—As the largest consumers of world energy, the U.S. is counting on natural gas to play a greater role in our energy mix. The U.S. Energy Information Administration (EIA) predicts U.S. demand to increase 14 percent from 2008 to 2035 with heavy growth in the industrial and utility sectors, which means infrastructure for extracting, transporting, and storing gas is increasingly vital.

Companies like Canada’s Talisman Energy and it’s U.S. partners, are racing to build that infrastructure by putting down and protecting essential pipeline in rough, rural areas like the Marcellus Shale region of northeastern PA where severe climates can be challenging and requires new technologies like TerraThane polyurethane foam systems.

Tensar Wins Patent Cases Against Chinese Infringers

October 11, 2011 rockman Comments Off

Tensar TriAx Geogrid

International ground stabilization specialist, Tensar, has successfully defended its TriAx product range against several Chinese patent infringements.

The TriAx geogrid – patented in many countries around the world by Tensar for use in ground stabilization, road, rail and other applications – has received numerous awards for innovation and achieved considerable commercial success since its introduction only a few years ago.

Several Chinese manufacturers and their distributors attempted to take advantage of this success by producing similar triangular aperture geogrid products, thereby infringing upon Tensar’s TriAx patent.

Challenging WV Transmission Station Pipeline Job on 58-Degree Slope Uses TerraThane by U.S. Company, NCFI Polyurethanes

September 21, 2011 rockman Comments Off

MOUNT AIRY, NC—A recent pipeline job at Dominion Resource’s extraction/fractionation plant in Pine Grove, WV presented some pretty hairy challenges. First the pipeline was to be laid on a 58-degree hillside. Trucks, excavators, and other equipment had to be wenched up the slope and held in place by cables attached to heavy equipment. Secondly, it was the rainy season, so erosion of the freshly turned earth was a major concern. [Editor] Click through for the rest of the press release. [/Editor]

Minnesota Company Transforming Highway and Bridge Repair by Using NCFI Engineered Polyurethane Foam

Foamjacking in Fargo

August 11, 2011 MOUNT AIRY, NC—Gary Molstre, owner of Mudpumpers Mudjacking, Moorehead, MN, says there is no chance they are changing the company name, but they are definitely changing the material they use to repair highways and bridges to an engineered polyurethane foam system and they’ve coined a term for it: “foamjacking”.

Mudjacking, also called slab jacking, concrete lifting, concrete raising, and slab leveling, is the traditional method of fixing damaged concrete highways and bridge approach panels. The process was developed in the 1930s and involves pumping “mud” (everything from clay, sand, and loam, to Portland cement, fly ash, lime, casting plaster, and hot asphalt have been used) beneath concrete slabs that have become uneven, sunken, and/or pulled away from bridge approaches due to soil erosion and/or the soil being compacted or compressed from the sheer weight of the slab. Mudjacking involves drilling holes in the concrete and pumping “mud” and pressure beneath to lift the slab to its original place and keep it there.

Nicholson Completes Emergency Response Grouting Operation on Major Missouri Interstate with Minimal Traffic Impact

June 24, 2011 rockman Comments Off

Pittsburgh, PA – June 2, 2011 – Missouri’s Interstate 44 is considered one of the most frequently traveled highways in the central United States. In early March of 2011, Nicholson Construction was contacted to perform an emergency response grouting operation on the Gasconade Bridge, part of I-44 westbound, over the Gasconade River in Laclede County.

During construction of the drilled shaft foundations for Temporary Bent No. 6, it was determined that voids were present both beneath and adjacent to the north footing for Intermediate Bent No. 6. Test borings by MoDOT indicated that the void varied in depth from zero to five feet, but the horizontal extents were unknown upon Nicholson’s arrival to the site.
