Upgrade Your Deck to Amazing

The StoneDeks SilcaGrate is a revolution in the deck-building industry. Go beyond wood or composite materials and open up a world of choices!

Introducing the SilcaGrate™

The SilcaGrate™, developed by StoneDeks, is a patented structural underlayment system that turns ordinary wood or metal-framed decks into durable stone, paver, brick, or tile surfaces.

  • Material: Made from thick, engineered recycled polymer, SilcaGrate has a hexagonal honeycomb structure that provides support every 2 inches.
  • Dimensions & Weight: Each grate measures 16″ × 18″, is 1.5″ thick, and weighs about 4 lbs.
  • Certified Strength: Tested to hold over 500 lb per grate for at least 30 days, supporting heavy surface materials safely.

How the SToneDeks SilcaGrate™ WOrks

For new construction or existing deck framework, the StoneDeks SilcaGrate™ is an easy upgrade that adds the beauty of stone, Travertine pavers, porcelain tiles, or brick to your outdoor oasis. Our SoilGrid® is the perfect partner to join your deck and hardscape in a unified design and style.

Installation on Joists

Placed directly over joists (wood or metal) for new construction.

Inside of joists with cleats for existing deck structures. The grates are screwed in using #9, 3″ deck screws at each corner.

Cutting & Fit

Grates are easily trimmed with a handsaw or circular saw to fit edges, around posts, or to adjust layout.

Accessory Layers

SilcaMat™ or geotextile blankets are laid over the grates for mold resistance and noise reduction.
SilcaSpacers™ ensure uniform spacing for tile or stone joints, improving alignment and drainage.

The SoilGrid® HS30 is a heavy duty linking grid system that allows you to build stronger hardscapes by stabilizing the base material and without heavy construction equipment.

Excavate And Prep

Excavate base base to ½ of ICPI or local building code. (may vary with soil conditions). Install geotextile fabric. Install aggregate base and compact.

INstall SoilGrid®

Start installation at a corner of the area. Each SoilGrid® interlocks to give you an easy, straight, and solid foundation. Fill the installed SoilGrid® with aggregate and compact to level.
