#2 ADHESIVE  DL-Dry-Laid

The paver surface has internal strength that doesn't require it to be glued to the GratedeX® underlayment to achieve it's strength. The Perimeter pavers are glued to the GratedeX® underlayment and glued edge-to-edge. This creates a curb to retain the internal paver surface. Other trim materials can also be added. A sheet of construction fabric is placed over the GratedeX® underlayment. Internal pavers are placed onto this fabric, dry-laid edge-to-edge. No sand is placed either under the pavers or in the paver joints.
 
#3 UNDERLAYMENT  GratedeX® 4x4 panel

The GratedeX® underlayment is an FRP structural panel. It's designed to suport live loads of the stone/tile surface and of pedestrian foot traffic with span supports between 16-24" O.C. The panels are 48x48 inches x 1 inch thick. They are designed with open voids for water drainage. Panels can be cut to any dimension including for use as stair treads and riser. When placed over a framed bearing surface, the Bite-Tite® fasteners secure the panels in position. The Weld-Tite® adhesive can be used to add additional strength to the flooring system or to bond panel edges at stair treads and risers.
