Are you tired of staining your deck?

What is a Stone Deck?

10 Years

Silca System ® is an American made plastic grate that installs on top of wood or metal deck joists and supports any stone or paver of your choice, transforming your wood deck to a stone deck. Silca System ® grates are made with recycled plastic and are certified to meet building standards by the International Code Council.

What are the advantages to using the Silca system ®?

  • No more cleaning, staining, or sealing wood
  • Decks last longer (wood framing is protected and the Silca grate™ creates an air gap that keeps the deck frame from molding and rotting)
  • You can match your hardscape to an existing or future deck surface
  • You can choose from thousands of styles and colors of stone
  • You can put a stone patio on a steep incline without the cost and labor of backfilling and retaining walls and settling issues
  • You can use for raised walkways, ramps, pool surrounds, docks, patios, balconies, or rooftop decks.
  •  Non-proprietay – use any stone that you choose
  • Resolves Ground level up lift issues in problematic soil areas
  • You can literally run your hardscape up the steps and right onto your deck
  • Easy to install, easy to cut -*
  • Eliminate the intense heat, fading, and warping of composite decking.

silca system stone tile deck testimonial

Silca grates allowed me to do “the impossible”. I didn’t have to worry about future problems and costs because of termites, rotting, or the effects over time of north Texas summer heat and winter freezes. “Grateful” is the appropriate word for how I feel about Silca grates! You made the impossible possible.
Your fan — Shelly Moore
