Laying Flagstone

Laying flagstone is best summarized in the following seven steps:

  2. Digging
  3. Adding base layer gravel
  4. Installing leveling sand
  5. Puzzle assembly
  6. Level that flagstone!
  7. Finish up the gaps

Any proficient flagstone installer will tell you that each step to the process here is its own micro-form of art. But these are the basics to get the job done.

How to Lay Flagstone – The Process

Below, we’ll give you some insight on what you can expect if you become the new architect for your flagstone landing!

  1. Planning: Before we can talk about setting flagstone, you’re going to need to plan out exact dimensions for your flagstone patio. You’ll need to consider the grading of your yard, stone size, and any utility lines before you break ground.
  2. Digging: Knowing how to install flagstones means being handy with a shovel. Once you’ve got a hunch of how big your flagstone patio is meant to be, you’ll want to dig down about 6”. This gives you 3-4” for the gravel base, 1” for any necessary leveling material, and the slabs themselves, of course.
  3. Add your Gravel Base Layer: Remember that 3-4” of gravel we mentioned? You’ll need to fill in your dug-out trench with a sturdy base layer of gravel and compact it nice and tight. It’s the foundation, after all!
  4. Leveling Sand: There are specialized sand and rock products that can assist you in leveling your base layer. This will be important for having an even patio to walk on.
  5. Puzzle Assembly: Now that you have your flagstone base, time to let loose and design your patio contractors. your next yard project with us.
