Marble is a hard and durable rock that's been formed when heat and pressure meets limestone. Marble comes in a variety of colors, and is commonly used as a building material, in gardens or for drainage.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Frequently used as a base for paving, and for making concrete.
Slate is a fine-grained, layered rock formed from sedimentary rock composed of clay or volcanic ash. It is formed by heat and pressure being applied to shale-like rock.
A porous, light-weight volcanic rock, frequently used in fire pits.
A multi-colored crushed stone that has colors ranging from deep red (almost purple and black) to cream and tan. This is a quarried, crushed and screened product so it is sold with some pit-dust on it. Just spread it, hose it down and you'll see these beautiful colors.
River Rock is rounded and smoothed by natural water erosion and tumbling action of the stone in streams. This stone is used on walkways, water features, rock gardens, as edging for plant beds and to create dry creek beds in yards.
Gravel that consists of small, rounded stones used in concrete surfaces. Also used for walkways, driveways and as a substrate in home aquariums.
Granite gravels are tough and long lasting. Ideal for driveways, walkways, patios and even as a substitute for sand in bases.
