Why does my glued timber floor sound hollow when I walk on it?
From a professional specification perspective:
Hollow or drummy sounds in adhesive-fixed floors over concrete slabs do not necessarily indicate a problem. They are caused by undulations in concrete slabs (up to 3mm over 3m is typical) and adhesive application methods, and moisture-curing polyurethane adhesives remain with some degree of flexibility. FSA Network floor sanders can assess whether hollow sounds in your floor are normal or require attention.
