How to Level a Slate Walkway

The slate walkway and patio are great features on this house, but they're both in need of serious repair. Eventually all of the stones will be re-laid, but for now we're fixing the worst stones that pose a tripping hazard.

Step 1: Pry up Stones

Use a pry bar to lift uneven stones.

Step 2: Pour Builder's Sand

Create a new base with builder's sand. This coarse sand is very gritty and will hold the slates in place.

Step 3: Level the Slate

Leveling the slate is a matter of trial and error. You'll have to adjust the amount of sand and use a level to make sure the slate is level.

Step 4: Plant Moss Between Cracks

There are cracks in the slate patio, and we decided on a temporary solution — moss. By planting moss between the cracks, we give the patio an English feel, matching the style of the house and concealing the cracks.
