An aging prison building in Fort Worth, Texas had seen areas of settlement as much as 7.5 inches inside the building. URETEK successfully implemented their URETEK Method to lift the sunken slabs and stabilize the […]
The residential high-rise Millennium Tower in San Francisco has settled a total of 16 inches since opening, 2 inches deferentially. A spokesman for the tower owner blames the settlement on the excavation next door for the Transbay Transit Center, a $2.4 billion dollar project being constructed 60 feet underground.
However, the Transbay Joint Powers Authority (Transbay) hired geotechnical firm Arup in 2010. Their initial report indicated that the tower had already settled 10 inches by the time excavation began for the Transit center. Arup seems to have been tasked with design, installation, and perhaps monitoring of a geotechnical monitoring program, some information on the scope is available in a 2012 presentation given by Arup available on the Transbay website.

New Solution Saves Money and Time Preventing Loss of Grain and Equipment DamageMOUNT 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.”

Turning a 119 year old brewhouse into a four-star boutique hotel is no easy task. For the project to be a success, the structure had to literally be raised from it’s grave.
Pearl Brewery operated from 1883 until 2001 in their downtown San Antonio, Texas location. It was once the largest brewery in Texas, and even kept afloat during the Prohibition era. Today the 22- acre Pearl site grounds has become a culinary gathering place where you can eat, live, learn, and play on the banks of the San Antonio River.
Renovating the original building would be no easy task for the developer. The building had settled approximately 5 inches. URETEK ICR successfully used their patented URETEK Method® to lift and stabilize the foundation with geopolymer.
