Post-tensioned rock and soil anchors provide a cost-efficient, high-performance solution for projects associated with temporary and permanent soil stabilization. The compressive stresses resist the anticipated tension stresses induced by the soil movements, enhancing the performance over a non-prestressed foundation. Soil or Rock Anchors generally consist of steel elements (bars or strands) grouted in a drilled hole. That means the anchor is pre-loaded with the design load plus any accounting for losses. Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations.
