Until it dries out you need any kind of hole that you can get a pump in and keep the water below the floor. I grouted the tile, then. How this works is when you drill the hole in the concrete and you lock down on this nut, it starts to pull up this wedge here, that goes around the bottom diameter, starts to wedge in to this end, and then it tightens up and it doesn't pull out. After drilling through the wood, we then used the rotary hammer drill and drilled into the cement/cinder block. Free delivery and returns on all eligible orders. One lovely day we decided it was time to insulate one of the rooms in our basement (really just a little closet). SERIOUS WARNING ABOUT CINDER BLOCKS. Concrete block foundations that are about 8-feet tall have a history of developing horizontal cracks about 4 feet up from the floor.
