Wood planks pop when you walk on them

Q: My house is almost two years old, concrete slab, wood floor B****-Manufacturer (glued down). There is a section of my living room where the wood planks pop when you walk on them. All the pops seem to be in a line (where the concrete floor had a small crack due to settling). How do I fix these pops?

I’ve heard that I have to drill a small hole and inject wood glue or a putty, to fill the gap between the concrete and wood.

A: The only thing I can suggest is to use an injectable adhesive. Bostik makes just such a product.
