Important Information for Installing Silca Grates

Installing Silca Grates
Silca System has the unique advantage of allowing customers to pick and choose their own deck surface material. When choosing a finished material for your deck, make sure the material is between 3/4″ and 3″ thick.

Installing Silca System by Doorways

But, before you decide whether to go with thinner or thicker material, measure everything on and around your deck carefully, especially the amount of space between your doorway base and the top of your deck material. The last thing you want is to install your deck only to realize you can’t open your door!

Installing Silca System on Joists

Silca Grates are made to fit directly onto a standard 16” decking base. The side edges for each grate should be directly centered on the joist. To support the weight, each joist needs to be at least a 2×8”.

For strength and durability, every other row should begin offset by half the length of a grate. So, you’ll need to start each row by alternating half and full grates.


Tools Required for Silca Grate Installation:

• 3” #9 deck coated screws (You want coated screws to prevent rust in the treated wood of the deck frame)

• Landscape fabric and paver jointing sand (not required)

• Common construction tools: level, measuring tape, and pencil

• A drill or power screwdriver

• Circular saw

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.
