1. Crushed Gravel

[amazon bestseller=”crushed gravel landscaping” items=3 grid=3 button=none]

Easily the most common option for use under decks as well as for most other outdoor applications, crushed gravel is widely available just about everywhere rock is sold. There are different types of gravel out there, but the term “crushed gravel” usually refers to pea gravel. This type of gravel features smooth surfaces that are natural instead of polished and is made up of tiny pebbles that have rounded sides.

  • Neutral colors that match well with just about any type of decor
  • Easy to find and even easier to work with

  • It can be costly to cover large spaces with crushed gravel, and so it may not be ideal for every low-budget need, depending on what you’re looking for.
