In response to a demand for predictable high capacity foundation solutions, a fully grouted screw displacement pile was developed by CHANCE® engineers. Comprised of a centralized steel shaft and a patented displacement assemblies, the pile, known as the Drivecast™ screw displacement pile, is designed to create a cylindrical annulus around the central shaft that is continuously filled with grout from a gravity-fed reservoir at the surface.
Traditional foundation methods can be tricky to implement when access is limited, overhead clearance is especially low, or soil conditions call for strict weight limitations. For instance, on swampy ground or low-quality soil, the machines needed to install conventional foundations cannot always operate safely or maneuver effectively.
Caliche is best described as salt-cemented sand. Naturally occurring in arid and semi-arid regions, caliche is a dense, thick layer of rock-hard ground that anchor installing machines can barely scratch. CHANCE® engineers, wanting nature’s toughest test for their ROCK-IT™ helical anchor, took product to the Atacama Desert in Chile, to see if the square shaft anchor with a carbide tip welded to the shaft would live up to its name.
