His problem was one we seldom see. The building footings, walls, columns and part of the roof were constructed but no concrete slab had been poured. Several inches of water were standing on the dirt of the building pad. With the roof shading the pad it would take a very long time to dry out. We mobilized a machine to the site and mixed the soil 8 to 12 inches deep. This dried up most of soil. In the areas that were extremely wet we spread quicklime at 1% and then remixed. After 3 days the 200,000 square foot pad was dry and workable. Problem solved. Spring rains had created a muddy mess inside this building under construction. Mixing the soil 8 to 12 inches deep dried up most of it. In the wettest areas, quicklime was mixed in to finish the job. Mixing the soil inside the building required careful maneuvering around the many columns. After one pass, most areas were ready for compaction.
