What to put between stepping stones?
If you are installing individual stones for each step, the area between steps can be made up of decomposed granite, rock, or even filled in with groundcover plants or sod.
If the stones for your pathway are being installed next to each other to create a pattern, smaller rocks or fine aggregate can be placed in between the stones.
For tight-fitting applications such as a paver or travertine stone pathway, we recommend you broom sand or polymeric sand between the joints to prevent shifting.
