When working on a clean concrete subfloor the glue down method is often the go to choice.
Glue down hardwood floor problems.
Buckling occurs when the wood flooring actually pulls up from the subfloor lifting several inches in one or more places.
Glue down hardwood floor installation reduces but does not eliminate wood movement the adhesives used to glue wood down to a subfloor make for an extremely strong bond.

The glue down method of engineered wood flooring installation is typically the most common and creates a highly stable floor.
Floor buckling is the most extreme reaction to moisture in a hardwood floor.
Newer adhesives are elastomeric.
Boards adhere well to the rough surface of the concrete subfloor and therefore lead to less gaps or planks lifting and buckling.
Fortunately this is not a common occurrence.
Improper floor preparation using the wrong adhesive or applying incorrect amounts are all common pitfalls of a failed flooring installation.
The elasticity in hardwood flooring glue ensures that the hardwood will have an ample amount of space to expand and contract without causing the glue to crack or separate.
