# Slab moisture test

A term used when buying flooring.

The relative humidity read from inside a concrete slab before anything is glued to it.

Moisture is the cause of most flooring failures over concrete, and the maker's warranty is written to require documented testing, so a shop that does not test carries the tear-out and the reinstallation itself. The in-situ probe method is the current one; the older surface method measures something different and is not interchangeable with it. Ask for the reports on the last twenty commercial jobs. A shop with none is carrying an unpriced warranty book that arrives with the company.
