What is StoneDeks?

StoneDeks is a structural system that makes it possible to install natural stone, porcelain, pavers, and other compatible hardscape materials over wood or metal deck framing. Instead of finishing an elevated deck with traditional wood or composite boards, StoneDeks allows you to create a durable hardscape surface.

What is Elevated Hardscape?

Elevated Hardscape brings materials traditionally used for ground-level hardscaping—such as natural stone, porcelain, and pavers—to decks and other above-ground outdoor spaces. StoneDeks provides the structural system that makes Elevated Hardscape possible.

Can you really put stone or pavers on a deck?

Yes. StoneDeks SilcaGrate™ installs over properly designed deck framing to create a structural support layer for compatible natural stone, porcelain, brick, and concrete pavers. This makes it possible to create a hardscape surface where traditional deck boards would normally be used.

Are stone and pavers too heavy for a deck?

Stone and pavers are heavier than conventional decking, so the deck structure must be designed or evaluated for the intended loads. StoneDeks provides technical resources and design information to help building professionals properly design the supporting structure.

Can StoneDeks be installed on an existing wood deck?

In many cases, yes. If the existing deck structure is suitable for the intended loads and application, the old decking can potentially be removed and replaced with the StoneDeks system and a compatible stone or paver surface. Existing structures should be evaluated before installation.

Do I need a concrete slab to have a stone deck?

Not necessarily. StoneDeks allows compatible stone, porcelain, and pavers to be installed over properly designed wood or metal deck framing, opening up possibilities for stone surfaces in places where conventional ground-supported hardscape or concrete construction may not be practical.

What materials can I put on a StoneDeks deck?

StoneDeks can support a wide range of compatible hardscape materials, including natural stone, porcelain pavers, concrete pavers, brick pavers, and other suitable products. This gives homeowners and designers much more freedom in the appearance of an elevated outdoor space.

Where can Elevated Hardscape be used?

Elevated Hardscape can be used for many above-grade outdoor applications, including elevated decks, second-story decks, balconies, rooftop decks, stairs, pool areas, terraces, and other outdoor living spaces where traditional ground-supported hardscape may not be practical.

Is StoneDeks a new or unproven system?

No. More than 2.5 million square feet of StoneDeks SilcaGrate™ has been installed across residential and commercial applications. StoneDeks also provides technical documentation and professional resources for the design and installation of the system.

How do I know if StoneDeks is right for my project?

Start with the outdoor space you want to create. StoneDeks may be a good fit if you want the beauty and durability of natural stone, porcelain, or pavers on a new elevated structure or qualifying existing deck. A StoneDeks professional can help determine the appropriate system and structural requirements for your project.

Maintenance and Safety

How hot does a stone deck get in the summer?

The temperature of a stone deck depends on factors such as material type, color, and exposure to sunlight. Natural stones and porcelain tiles tend to maintain cooler surface temperatures compared to materials like concrete.

Does a stone deck get slippery when wet?

Slip resistance varies by material. Many hardscapes used around pools are designed with slip resistance in mind. When selecting pavers, research their slip resistance properties and refer to the manufacturer’s specifications.

How can I keep my patio dry underneath a stone deck?

To keep the area beneath a stone deck dry, consider installing an under-deck drainage system and building the deck with a slight pitch to facilitate water runoff.
