Quoted from Rdoyle1978:
With respect, Dricore is supposed to be floating. In extreme circumstances, they do say you can attach to the floor, but doing this can wreck the benefits of the product, since the little feet are now pierced
Well that’s weird. Because the DriCore Products YouTube channel installation video says it should be secured with Tapcons.
The person asking the question said they were due for new carpet.
On the dricore website, under the carpet section is specifically states “To prevent panel uplift when stretching carpet, fasten DRIcore panels to the concrete floor with flat head 1/4" x 2 1/4" or 2 3/4" concrete fasteners every other panel at perimeter edges and one in the panel in the centre of the room. Use a 3/16" x 4 1/2" drill bit to bore the holes.”
