Tried to glue as I didn’t have a drill strong enough to penetrate concrete. For me it was impossible to install as the item is two separate pieces, not connected at all. You need to tape to keep accurate. Impossible for me to keep it accurate while holding for glue to set (5 minutes). Instructions are lacking in my opinion. I tossed and ordered a different item where you measure the cracks and record the measurements.
