Quarrying limestone is the process of removing this material from the ground. As with any quarrying process, there are certain pros and cons that must be evaluated.
1. It can be an economic engine. Quarries can provide numerous jobs at the local level. People can work at the quarry to extract the limestone that is needed. Drivers are needed to transport the limestone to where it will be processed or used. Processing facilities hire handlers to create usable products from the delivered materials. Local service industries are needed to support these workers.
2. It is often in high demand. The market for limestone is remarkably consistent. Quarried limestone can be used to neutralize acidity, so it can be added to soils or lakes. Limestone is used in the iron manufacturing industry, is required for cement, concrete, and mortar mixes, and is heated with sand and sodium carbonate to create glass.
3. It is extremely affordable. Compared to other building materials, the cost of quarried limestone is much lower than most options. A 50-pound bag of limestone chips, for example, can be purchased for around 30. Limestone pavers are about 300 per every 100 square feet of coverage. Although costs are dependent upon the amount of refinement and the final purpose of it, there are few other materials that can match the cost profile of quarried limestone.
4. It is durable. Quarried limestone is a durable building material. The Great Pyramids were built using limestone. Modern buildings have stood for centuries with this material. It is also easily accessible near the surface, which makes it possible for most quarries to have a minimal impact on the surrounding environment. At the same time, it also handles exposure relatively well.
