MOUNT AIRY, NC—The 12-year-old riverfront Convention Center in New Bern, NC was in trouble. The building’s exterior is supported by pilings driven deep in the ground, but the floors sit directly on the earth and silt of the old riverbed. The land was in-filled by old docks and building debris in the 1970s and settling, erosion, and construction mistakes were taking their toll on the building.
Parts of the floor and patio sunk up to seven inches, cracks and uneven joints in the concrete slab floors were causing walking/tripping hazards, and gaps beneath walls were allowing sound to pass between what were designed as soundproof rooms.

MOUNT AIRY, NC—In-ground parking garages in Dallas, TX experience the same thing: erosion of the soil beneath them, and silt infiltration that overwhelms and clogs the drainage system, thus causing more and worse erosion. The keys are catching it early enough, and choosing the right solution to keep it from happening again.
The three-story, in-ground parking garage at McKinney Ave. and Worthington St., the main thoroughfare of the Dallas’ “Uptown” area and home to some of the poshest apartments, business addresses, shopping, hotels, restaurants and bars, had silt and water infiltration, so the owners called in Edens Structural Solutions, Bixby, OK, with 30 years experience of structural lifting and repair. David Edens, company president, says they studied the problem and decided on geotechnical polyurethane foam. “Our solution was to use void-filling TerraThane geotech foam. It’s simple to apply, expands and cures in place, and is an excellent water and air barrier,” says Edens.

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]
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.
