MDL is an “Oneota Limestone” that has been called “Winona Travertine” because its solution cavities give it a texture similar to spring deposited limestone, though it is a sedimentary limestone of the Ordovician Era. Its composition is primarily calcium carbonate and magnesium with traces of quartzite.
MDL is exceptionally hard and durable (qualifies as a Class III limestone), and is available in a variety of colors including light cream to buff, light grey to bone, and light gold to yellow tones – depending on the desired finish. These warm and neutral tones have made MDL the choice of architects and designers throughout the country.
The strength and durability of MDL has made it a popular choice for a variety of facility types throughout the country including healthcare, churches, higher education, banking and insurance.
