About Silca System

Silca Grate™ Transforms Wood Decks to Stone Decks.

You’ll Never Have to Stain Your Deck Again!
When building their hives, honeybees rely on hexagons. Silca System® mirrored this naturally-designed hexagon technology in the creation of Silca Grate™. “But, why?” you ask. Simple: the hexagon design creates a super-strong substructure (subfloor) capable of sustaining heavy deck materials, such as brick, travertine, slate, granite, marble, and natural stone, thus giving you more decking options than you ever thought possible!

Silca Grate transforms wood to stone decks

Silca Grate™ grids measure 16×18” (2 square feet) and are composed of durable 1 1/2” thick engineered polymer.  Not only is Silca Grate™ suitable for elevated decks and patios,  but it can be used for ground applications, porches, bridges, pool decks, rooftop decks, and more!  How is it possible, you wonder?  The 2” diameter honeycombs on the Silca Grate™ grids offer 360 degrees of solid support, allowing Silca Grate™ to not only meet residential and commercial building codes, but to exceed them.

That all sounds good, so what’s the catch? There isn’t one!  Not only is Silca Grate™ UV stable and    easily cut to form, it is also quick and easy to install.  In fact, you can install it yourself!  To secure Silca Grate™ to your deck frame, put 4 screws into the floor joists spaced 16” on center and you’re good to go.

Silca System’s®  Silca Grate™ can make your dream of having the perfect, low-maintenance, stone deck and entertaining area a reality!  Don’t wait—transform your deck or patio from ordinary to extraordinary today!

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
