Structural stone, tile or paver outdoor floor floats above waterproofing.

Floors must be nailed, fastened, screwed or in some manner secured to the bearing surface that supports the flooring surface material. That was opinion at one time. But with changes in interior floor installation, that's no longer the case. It's possible to float a floor without attaching it to the surface it's sitting on.

And now it's possible to accomplish the same installation method for your outdoor floor with the GratedeX® Outdoor Floor System™ No fasteners. No penetrations into or through underlying waterproofing or other surfaces. No attachments.

The GratedeX® underlayment panel is a structural decking underlayment that's free-draining and inert to moisture. It provides a solid support surface for thin gauged stone or tile. This and other surface materials are bonded to the underlayment with the Hold-Tite® adhesive providing a permanent flexible attachment. Open joints between stone or tile allows for surface drainage to the waterproofing surface below. Each GratedeX® panel is supported above the waterproofing with a 1/2" drainage space and interconnected to adjoining panels with the Ped-Tite® pedestal discs.

Get creative with the finished surface. Thin-gauged stone or tile glued to the GratedeX® panel is light-weight and allows for future panel removal for maintenance. Pavers? No problem. Dry-lay modular pavers with the same free draining and maintenance access benefits. Need some fun? How about artificial turf or a rubber style floor mat? A rooftop garden? All and more can be supported with the GratedeX® Outdoor Floor System™

And if uplift is your concern, don't worry. The GratedeX® underlayment panel with a glued thin-gauge stone or tile surface falls within the Dade County Florida hurricane uplift requirements for a single panel weight but is still light enough to be removable for maintenance. It stays in place when you need it to.

It's simple. It provides unlimited creative flooring options. It's maintenance free. It's durable. It's a beautiful outdoor floor, rooftop terrace deck or on grade patio.
