Typical applications are deepened foundation anchors for new construction and stabilizing/lifting repairs of existing foundations. Compression loads and soil conditions dictate the Chance anchor solution. In many soils, the steel anchors alone provide the needed performance. Only where soils are near “impossible,” do Chance anchors and grout need to be combined. HELICAL PIER® Foundation Systems anchors are designed for installation ease and to maximize load capacity of each helix. This method is effective in soil conditions which support the steel anchor shafts against buckling. HELICAL PULLDOWN ™ Micropiles anchors are designed for weak surface soil conditions. For higher loads such as commercial and industrial construction or expansion applications, these micropiles incorporate a grout column around the steel anchor shafts for added lateral support. Displacement plates added at extension joints form a void in the soil filled by a grout reservoir on grade as the anchor is torqued into the soil. Column may be sleeved during installation if required.
