Indiana limestone is one of the most popular landscaping stones used throughout North America. It is an extremely clean natural stone, with white, cream, and beige tones. Indiana limestone is suitable for residential and commercial projects, as it provides a timeless look and can match a variety of bricks and stone facades easily. While the beauty of this stone is obvious, the biggest drawback of Indiana limestone is it is extremely porous which means it can easily stain from plants, leaves, salt, and any other materials in the environment.
