Elevated Hardscape makes it possible to bring natural stone, porcelain, pavers and other hardscape materials to decks and other above-ground outdoor spaces. These frequently asked questions explain what Elevated Hardscape is, how the StoneDeks system works, where it can be used, and what homeowners and building professionals should know when considering it for a project.
What is Elevated Hardscape?
Elevated Hardscape is the use of hardscape materials such as natural stone, porcelain and pavers to create finished outdoor surfaces on structures above grade, including decks, balconies, rooftops and terraces.
Is Elevated Hardscape the same as a stone deck?
A stone deck is one type of Elevated Hardscape. The broader category also includes other elevated outdoor applications finished with hardscape materials, such as balconies, rooftop spaces, stairs and raised terraces.
Can stone or pavers really be installed over deck framing?
Yes, when the structure and support system are designed for the intended application. StoneDeks uses SilcaGrate as the structural underlayment between compatible deck framing and the hardscape surface.
Can StoneDeks be used on an existing wood deck?
Potentially. StoneDeks can be used in new construction and qualifying existing deck applications, but the existing structure needs to be suitable for the loads and intended use.
What materials can be used for Elevated Hardscape?
Depending on the application and system requirements, StoneDeks supports compatible natural stone, porcelain, concrete pavers, brick and other hardscape materials.
Does Elevated Hardscape require a concrete slab?
Not necessarily. One of the purposes of the StoneDeks system is to support compatible hardscape materials over appropriately designed wood or metal deck framing.
Can Elevated Hardscape be used in cold climates?
StoneDeks markets SilcaGrate for all-weather use. Project design, framing, surface-material selection, drainage and installation still need to account for the project’s climate and local requirements.
Is StoneDeks code compliant?
StoneDeks provides ICC-ES ESR-3748 documentation for SilcaGrate and technical resources for professionals. Project-specific compliance still depends on applicable codes, design and installation requirements.
