Hi Sandra, This is a special mix of two products and yes, it is the same material I specified for the front entry. It varies in thickness between 1/4" and 2-1/4" so you will need to purchase far more than you actually need and have a really good mason who can lay it for you. Also take into consideration that because it varies so much in it's thickness, much will become waste or become material used outdoors for walking paths etc. unless you are at a point in your project you can still make adjustments to door openings, etc. in which case, you won't have quite as much waste. We purchased it through Select Stone out of Montana. Thank you for your inquiry. If there is anything I can do to assist you, please do not hesitate to call me at (775) 432-2500.
