Arranging natural stone outdoors for a patio or walkway is not an easy job, but it is well worth the effort. The look of natural stone provides a sophisticated look without the extensive maintenance of a meticulously manicured lawn. To make the project easier, try to select stones that are relatively even and no more than 2 inches thick. This will enable you to handle them with less difficulty. This is a physically demanding task that ideally requires at least two people to assist you.

Difficulty: Challenging
Instructions

Things You'll Need:

  • Work gloves
  • Eye goggles
  • Back brace
  • Knee pads
  • Wooden stakes
  • Heavy string
  • Tape measure
  • Shovel
  • Carpenter's level
  • Plate compactor or manual tamper
  • Rubber mallet
  • Wheelbarrow
  • Coarse, pea-sized gravel
  • Masonry sand
  • Natural paving stones
  • Industrial broom
  • Water hose
  1. Step 1

    Use several small, wooden stakes and string to mark and tie off the area where the stones will be placed.

  2. Step 2

    Shovel out enough soil from the area to accommodate the average thickness of the stones selected, plus 2 inches (for instance, if your stones are 1 1/2 inches thick, dig down 3 1/2 inches deep). If the area where you are laying stone is adjacent to a home or other structure, create and maintain a gradual downward slope as you proceed in order to direct rainwater away from the foundation.

  3. Step 3

    Use a plate compactor or manual tamper to flatten the excavated area. Add 2 inches of coarse gravel mixed with sand. Flatten this mixture of sand and gravel with the compactor and spray it with a misting of water.

  4. Step 4

    Roughly arrange your stones over the base layer in a pattern that looks pleasing to you. Concentrate on one fourth of the total area at a time. Use a carpenter's level and a rubber mallet to level each stone in reference to the stone next to, above and below it. If necessary, add or remove sand to assist the process. Repeat for the entire area to be covered.

  5. Step 5

    Sweep sand with a stiff bristled broom over the stones and into the spaces between them. Mist the surface of the stones with water, moistening the sand well. Allow the sanded joints to dry in the sun for about two hours. Add more sand and water if needed to further stabilize the stones.

Tips & Warnings
  • Personally selecting your stones will ensure that you will be able to pick up the ones that you buy. Stones that are too large will have to be either cut or broken to make them a more manageable size. If you are grading the area to create a slope away from a building, as mentioned in Step 1, make sure that the decline is subtle. For every 3 feet away from the building, the decline should be no more than 1/2 to 1 inch. This means that a patio that extends for 12 feet should have stones at the end that are no more than 4 inches lower than the ones directly adjacent to the home or other structure. The intermediate stones should be graded gradually lower from the first row to the last, while maintaining a unified integrity between the stones in each row. When walking upon the finished patio, there should be minimal chance of falling or tripping due to uneven placement and the decline should be barely noticeable.
