Douds Stone LLC purchased Douds Stone Inc. in 2012. Douds Stone Inc. was founded in 1948 with the purchase of the underground mine in Douds, IA. The mine was started in 1927 and had been flooded in 1947. An estimated 200 million gallons of water were pumped out and the mine was in operation by July 1949. Over the next 40 years, four open pit quarries were developed. In 1989, the second underground mine was developed at the Lyle Quarry. In 2002, Douds Stone Inc. expanded with the purchase of six open pit quarries and one sand operation. Another sand operation was developed in 2005. Douds Stone Inc. currently operates nine open pit quarries, two underground mines and two sand operations.
