Limestone Gravel is a sedimentary rock with a wide range of uses in construction and landscaping. It is generally white, with a mixture of off-white, gray, and brown hues. Limestone is primarily composed of calcium carbonate and forms through various processes. 

Uniquely, limestone can be used as a soil amendment to improve soil structure and drainage. When mixed with soil, limestone enhances soil aeration and water infiltration, promoting vigorous root development and plant growth. The calcium carbonate content in limestone also assists in neutralizing acidic soils, rasing the soil pH to a more favorable balance for most plants.
