Drawing on over 190-years of built projects found throughout north America and around the world, the mission of the Indiana Limestone Institute is to ensure continued and relevant promotion, education and direct support in the design, application and care of Indiana Limestone through proven reference, research and technical data, resulting in projects of enduring beauty. Our publications include geological information on the deposit, history on our industry & the significant impact on our built environment, technical reference material, and numerous case studies. The ILI is voluntarily supported by its trade members and affiliates comprised of experts in the field.
