Landscaping projects often require the careful selection of natural stones. Two popular choices are sandstone and limestone. Each stone brings unique characteristics to outdoor spaces, influencing their aesthetics and functionality. 

‍

Limestone is a sedimentary rock, typically gray with color variations, formed from organic debris or chemical processes. It has played a significant role in Earth's history, often containing fossils, and can create fascinating limestone caves.

‍

On the other hand, sedimentary sandstone is mainly composed of sand-sized particles derived from minerals and organic materials. Found globally, it forms in areas where sand accumulates, with colors like orange, yellow, brown, and red. While fossils may be present, they are less common than in limestone. Sandstone is versatile in various applications.

Let's compare limestone and sandstone, considering appearance, durability, porosity, and typical landscaping applications.
