1. SilcaGrates™ should be installed with the straps to the top, facing upwards.
2. Natural stone can be adhered directly to the Silca Grate™. We recommend Surebond 190 or an equivalent. This can be done as a perimeter glue where the interior stones will remain in place by virtue of weight and friction, or each stone can be glued down if desired (stone must be evenly cut). Natural stone can be installed the same as standard pavers.
3. Only use polymeric sand when creating joint lines.
4. We do not recommend using exterior mortar to fill your joints or adhere your stones

You can glue the pavers you used for the deck flooring around the edge, or you can use pressure treated lumber, cedar, or redwood as edging.
When applying stone to steps, SilcaGrates should be installed with the straps up, then adhere the stone to the SilcaGrates using a construction adhesive such as Surebond-190 or equivalent.
StoneDeks System is the company that makes the Silcagrate. The Silcagrate is a sub-floor support system that allows for the installation of hardscape materials on elevated decks, walkways, and more. The grates are installed on the frame and support the weight of whatever hardscape material you use. StoneDeks System also offers other products, such as the Soilgrid, which is used for in ground application for stone pathways, patios, and other in ground projects.
Your deck flooring options are almost limitless: natural stone pavers, porcelain, travertine, blue stone, brick pavers, slate, marble, granite—in a variety of shapes, colors, and sizes.

The StoneDeks System is a very versatile system that can be used in a variety of applications, and that doesn’t end with existing decks! If you are just looking to renovate your current deck and bring new life to it by transforming it into a stone deck, then StoneDeks is still the right choice for you. Since an existing deck wouldn’t have been measured and built to account for the thickness of SilcaGrate, the installation is a little bit different but still just as simple. We have very useful training courses and materials on the website that can help you in both new and existing deck installations.
The dimensions of the Silca Grate is 16″ wide, 18″ long, 1 ½” thick, and weighs approximately 4 lbs.
It would not be recommended to install pavers on a deck without a proper support structure in place that can support the extra weight. That is where StoneDeks System comes in! The Silcagrate was designed to support the weight of hardscape materials while also being simple and easy to install. The grates are tested by applying over 500 pounds of weight on each grate for at least 30 days!
The use and application of StoneDeks sub-flooring System is very versatile and designed be used with a large variety of hardscape materials. You can use any hardscape that is at least ¾” thick up to 3” thick on our products. That leaves plenty of room for versatility and creativity!
The answer to this question can be pretty dependent on exactly what stone or hardscape material you plan to use. In general, a stone deck can be a bit more expensive than wood or composite to install. That being said, the long-term costs are considerably lower since there is little to no maintenance with a stone deck. For example, wood decks are definitely the cheapest option, but have a shorter life span and will require regular maintenance and upkeep every 3 to 5 years, while a stone deck won’t be susceptible to weathering and fading and rot like a wood deck would be so wouldn’t require the same maintenance and upkeep costs.
This would vary depending on a few different factors. First you would want to consider what material you are using. Pavers like concrete tend to get hotter than natural stone or porcelain tiles, which tend to maintain cooler surface temperatures. You would also want to consider the color of your pavers. Black tends to absorb the most light and therefore would hold the most heat. The darker the paver, the hotter the surface. Finally, you could always choose to put up a nice shade system to help maintain the temperature of your deck.
This again will be dependent on what hardscape material you choose to use. Keep in mind that hardscape is regularly use around pool areas and for decks around pools so the manufacturers of the used hardscapes have to keep this very thing in mind. When choosing what type of paver you are going to use, be sure to research the slip resistance properties of the material and refer to the manufacturers specifications.
If your stone deck is going to have a living area such as a patio underneath it, then it is suggested that you install an under-deck drainage system in order to keep the area dry. Also, the deck can be built with a pitch so that water runs off and away from the area underneath.
We have a very convenient and easy to use dealer and contractor locator on the website that allows you to search your location for the nearest contractor to you. We have dealers and contractors all over the U.S. and only continue to expand. If you are having trouble finding someone in your area, feel free to contact us or have your contractor contact us so we can help in getting you everything you need.
While the primary purpose of the StoneDeks system is for the installation of hardscape on decks, it can be used with Astroturf as well. We have had people use this around pool decks and the results look amazing. It is suggested that a good sturdy geotextile or our SilcaMat is placed underneath the Astroturf to give the turf a more sturdy backing and prevent a chair leg going through the turf and the open grates.

1. Gauged flag stone can be adhered directly to the Silca grate™ we recommend Surebond 190 this can be done as a perimeter glue where the interior stones will remain in place by virtue of weight and friction or each stone can be glued down (Stone must be evenly cut) Natural stone can be installed the same as standard pavers.
2. We recommend using polymeric sand.
3. We do not recommend using exterior mortar to fill your joints or adhere Gauged flag stone can be installed in the same manner as natural stone or standard pavers depending on how even the sides are cut.
4. We do not recommend using exterior mortar to fill your joints or adhere your stones Recommended methods of finishing the outer edge of deck (Rim Joist, Fascia), Wood or Composite decking material can be used, Pavers or natural stone can be used to finish they can be adhered with recommended glue and use of either a temporary or permanent ledger board.

Non gauged flag stone installation is possible with Silca grate™, however in this instance two layers of geotextile fabric and base of bedding sand needs to be used and all sides of the deck need to contain the sand and stone. As you lay each stone down it must be seated in the sand and then and leveled to the stone adjacent to it. Try to keep the joint lines between stoned to a minimum width This process needs to be repeated through the entire installation. The stone will not by its nature be completely level, their will me high and low spots.
