GCS started in 1990 with 1 Quarry, and we’ve been growing ever since. We now quarry out of 5 different pitts which produce a large variety of stones available in many different colors, textures, shapes, and sizes. Our Rock Island Quarry is a large producer of “Hackett” material.


GCS is a wholesale company that sells to stone yards. We don’t offer exclusives, but we do our best to protect our customers. If our stone is represented on a yard in your area, we will guide you in the direction of who you need to contact to get the materials you are looking for. If there is not a yard in your area that carries our products, we will make every effort to help you get the stone you need.


At GCS we work as a team to provide the best possible customer service. From the office staff to the yard staff, we vow to do our best to accommodate our customers.
