Granite Step Fillers

$32.00

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.

FAQs

Please read our FAQs page to find out more.

What are granite step fillers used for?

Granite step fillers create the structural base and risers under granite steps and platforms, replacing poured concrete or solid step blocks.

How tall are the fillers and will they match my steps?

These fillers are 7” high to match most exterior granite step heights, keeping each riser consistent and comfortable.

Can I use fillers instead of solid granite steps?

Yes, many contractors build stairs by stacking granite fillers and then topping them with granite steps or platforms, a proven alternative to full solid steps.

Are granite step fillers suitable for winters and de‑icing salt?

Granite is one of the most durable natural stones for freeze–thaw climates and, when properly maintained, stands up well to snow, ice, and de‑icing products.

Do I need a concrete footing under the fillers?

Installers typically set granite fillers on a deep, compacted gravel base and, for larger stair runs or poor soil, may add a concrete pad or footing for extra stability.
