I came across this video that introduces DAT Instruments, an Italian Company that builds dataloggers for geotechnical construction such as grouting, jet grouting, soil mixing, diaphragm walls and more.
Excavations in an urban environment often encounter contaminated soil and/or groundwater. GeoPrac sponsor Moretrench is an expert in geotechnical construction methods for preventing the contamination from entering or leaving a site. In a recent blog […]
PITTSBURGH, 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.

Instrumentation systems for geotechnical and structural monitoring often entail monitoring large numbers of sensors of different types with dataloggers often being installed in remote, inaccessible and hostile locations.
