Concrete Vs. Stone: Which Is More Cost Effective?

Concrete. Concrete is not made from natural materials and is instead formed using a number of raw materials mixed together at a manufacturing plant. Concrete is formed from a mixture of aggregate, cement, pigments and dye. These materials cost less to produce than stone, hence why concrete pavers are a more economical option.
