Not for most installations, but it is required in some installations. Below is a list of conditions that require fastening:
If a power carpet stretcher will be used to install carpeting: prevent panel uplift when stretching carpet by fastening DRICORE® Subfloor panels to the concrete floor with Tapcon type concrete fasteners at perimeter edges every four feet plus one in the panel in the centre of the room.
If using DRICORE® Subfloor panels for a garage or workshop where the panels will be left exposed, fasten every second panel along the perimeter wall edges to the concrete floor to prevent lateral movement or shifting with heavy equipment or use. Keep in mind that DRICORE® Subfloor panels are not manufactured to be a finished floor nor left exposed to exterior weather elements.
If installing walls on top of DRICORE® Subfloor: use two fasteners for each 8 foot base plate, through the panels and into the concrete floor to fasten base plates.
If installing tile on the DRICORE® Subfloor panels.
