Indiana buff limestone is neutral in color and almost without blemish. The color is a warm white or buff. Slabs are typically used for large patios, wall cap, walk ways, pool coping and stepping stones. Indiana Limestone has no discernible grain structure, giving it equal physical strength in all directions. Combined with a high resistance to deterioration from weather and pollution, this stone is a great choice for any application where natural stone and crisp detail edges are desired.
