In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too weak to support the limestone stockpile, provisions were made to improve in-situ soil strength by surcharging using stage loading techniques. Vertical wick drains were installed to accelerate consolidation. In-situ soil displacement and stability characteristics were predicted using laboratory testing to evaluate stress history, consolidation characteristics and stress-strain-strength properties of foundation clays.
