Step 1: Ready Site

Lay out the design of the patio and excavate at least six inches of soil. Compact the subsoil to create a firm surface.

Step 2: Add Landscape Fabric

Lay down a layer of landscape fabric which will help to prevent weeds.

Step 3: Add Sand

Lay in three inches of sand and compact again.

Step 4: Add Gravel

Top off and level with class five gravel. If the patio is built near a house, pitch the foundation away from the house for water drainage.

Step 5: Lay Slate

Place large pieces first then fill in empty spaces with smaller stones. Use a chipping hammer to shape the flagstone until it is the correct shape for the area you want it to fit.

Step 6: Level Stone

Check each stone with a level, adding more sand beneath stones that are too low and compacting stones that are too high with a rubber mallet. Finally, use the handle of the rubber mallet to pack the sand firmly around the edge of the stone.
