Granite Step Fillers

Build long‑lasting exterior stairs with granite step fillers engineered to match standard 7” riser height and support heavy granite steps in any climate. Each filler is 6” wide with a rock‑faced front and precision machine‑sawn sides, giving you a clean architectural look on the face while keeping joints tight and easy to level for installers. Available in multiple lengths, these granite base blocks let you fine‑tune stair runs, entries, and landscape steps without custom cutting, making them ideal for contractors, landscapers, and homeowners upgrading concrete or timber stairs to natural stone. Use granite step fillers under solid granite steps to create uniform risers, better drainage, and a foundation that can handle heavy traffic, de‑icing salts, and decades of freezing weather.
