I installed engineered hardwood floors in most of my house last year.

The hardwood is glued to the concrete slab. There is one wood plank that has begun to lift off slightly. I am told that the way to fix it is to drill a small hole in the plank and inject glue under the plank.

Can this be done? Is there a special glue and injector to be used? Where can I get this?

Thanks.

There is a needle and syringe we use on full spread floors to get a spot that is a problem
You can drill a hole and get sub grade floor adhesive and glue it down

My biggest concern is the glue down on a concrete floor here to begin with and that may be the beginning of an on going problem.
You can get the needle at a REAL flooring store and while you are there explain to them your situation and they also will have a wealth of informant about your floor. Not to pick on anybody so many DIYs have Major problems because of just following the flooring instructions but don't understand the medium they are putting it on in heat and moisture. So I hope it goes well for you.

If it gets involved and you need test the floor for 5% or more moisture that may be in it. Put down an 18" x 18" piece of plastic and duct tape the sides. Let it sit for 16 to 18 hrs. If you see water droplets under that or any moisture the concrete is to wet with moisture

5% is the magic number here for a sealer on floors and to check coats of sealer.
