Construction of Stone Steps

If a garden area slopes more than one foot for every ten feet, consider adding steps. Garden steps are usually wide and shallow for easy walking and visual appeal. It is important to keep the risers and treads the same on each step to avoid tripping. Pitch steps slightly forward to allow standing water to drain quickly. To avoid erosion to the left and right of the steps consider low retaining walls or small boulders and ground cover.

Recommended Riser to Tread Ratios

Riser:                       Thread:

4-4 ½ “                   18-19”
5-5 ½ “                   16-17”
6-6 ½”                    14-15”

For a gentle slope, use steps with low risers and deep treads. For steep slopes, use steps with high risers and narrow treads.

Construction

• Starting at the bottom step, dig out a flat spot to set the rock.
• Add a thin layer of sand and set the rock onto it. Use the sand to level out the rock from side to side and pitch it forward a little from front to back.
• Dig out another flat spot farther back even with the top of the first step. Use any dirt around the back and sides of te first step.
• Add a thin layer of sand and set the next step onto it.
• Continue the same until you get to the top step.
• After the top step is set add some extra soil around the back and sides of it to make a level exit from the step.
   

 

Tips

Call OUPS Ohio Utilities Protection Service) at 1-800-362-2764, before digging.

Determine the overall height and set back of the stairs to determine how many steps you will need and at what thickness would be most appropriate.

Know the approximate weight of each step to determine if equipment is needed.

Remember to pitch steps slightly forward for drainage.
