Q: I had 3/8″ oak hardwood floors installed over the solid concrete slab. The slab was not properly floated and there are areas the adhesive did not adhere to the slab or floor and there are also areas of deflection.
What can be done to repair the floor without having the installer remove and replace the new floor?
A: There are injectible adhesives which can fill voids and grip both the sub floor and finished floor. This is providing we are not talking general adhesive failure.
