What types of natural stone are there?

Natural stone is identified by two different characteristics. What their mineral content is and how they are formed.If you didn’t sleep through your science class in school you may remember that there are 3 different classes of stone:(These are not all used for paving necessarily but can be used for other projects like countertops, veneers for walls etc.)

Igneous Rock: This is a rock made from molten (think hot melted cheese) minerals. It is cooked and then cooled. They are called Igneous because the term comes from a Latin word igniswhich means fire. Examples of Igneous Rock are:

Granite

Basalt

Sedimentary Rock: This is a rock made of sediment (loose stuff that settles and collects). It is pressurized over many years to create rock. Examples of Sedimentary Rock are:

Blue Stone

Sandstone

Metamorphic Rock: This is basically rock that has gone through metamorphosis (changing from one thing to another). It is one of the first two stones - Igneous or Sedimentary - that has gone through some type of process (usually a combination of heat, pressure and fluids) to change into something else. Some examples of Metamorphic rock are:

Slate

Marble

Which type of rock is flagstone?

Well flagstone is not really one type of rock. Flagstone is a term used to describe a stone being installed in “flags” or flat individual sections on the ground, wall etc.

Most consider flagstone a type of sedimentary rock like sandstone. Arizona flagstone is an example. It is a sandstone with a lot of warm natural color in it.

However there are quartzite flagstones as well and they are a metamorphic rock. It comes in different colors but mostly grey tones:

What are the advantages and disadvantages of using natural stone?

Advantages:
  • Well natural stone of course is beautiful when properly installed and well coordinated with the rest of your outdoor project.

  • Perceived value.

  • Can be re-polished in many cases if scratched.

  • Durable in the case of granite installations.

Disadvantages:
  • Cost - Natural stone is going to be one of the more expensive if not the most expensive option for your hardscape project.

  • Some stones like travertine require a lot more maintenance than concrete or other hardscape choices.

  • Certain stones don’t hold up well under certain conditions. For example, if you get a cheap Arizona flagstone and put it around a pool, the moisture can cause premature flaking of the stone.
