I've finished my basement including carpet and laminate floors. I have sliding closet doors in both areas.

What is the best way of attaching the door separator on the ground, knowing that it is concrete underneath?

Use plastic concrete/wall anchors with long pan head sheet metal screws. Pick the diameter whose screw matches the holes in the guide you are mounting. Use masking tape over the carpet and mark the hole locations using the guide you are mounting on the tape. Leave the tape in place while you drill the pilot holes. Drill through the carpet, pad and into the concrete. Make sure you drill deep enough in the concrete to completely sink the plastic insert.

Leave the tape in place or you will lose the holes. Insert the plastic inserts. If the carpet and pad is thick, be careful to push the insert into the hole as far as possible, then use a hammer over the hole to carefully seat the plastic anchors fully. They should be fully in the concrete. Place the door retainer over the tape and start the screws. Tighten the screws, drawing the retainer against the floor. Once in place, you can trim around the door retainer and remove any visible tape.

  • To Add. You will need a drill with hammer action, and a masonry bit. Also, watch when drilling through the carpet that the drill doesn't collect loose strands and rip strands from the carpet (it doesn't really happen but watch out)

  • This is kind of where I was headed mentally. For the laminate flooring could I just use an adhesive of some sort you think?

We usually just glue down a small piece of plywood directly on concrete and attach divider to plywood. You can slightly cut out laminate/carpet at the spot. The piece is just big enough to attach divider and really won't be seen at all.
