GeoPrac sponsor Nicholson Construction has started a chemical grouting project in Los Angeles at the Woodrow Wilson Classical High School to treat potentially liquefiable soils beneath the building. This $2 million project is part of a larger $21.1 million project to upgrade the infrastructure in the auditorium and adjacent areas. Nicholson will drill vertical, horizontal and inclined holes at depths of 14 to 24 feet beneath the structure and inject the chemical grout using a Tube-a-Manchette piping system.
