Cork does not absorb water or liquids which is why it’s been used for centuries as stoppers for wine bottles.
There are two ways cork flooring can be installed: glue down and floating. Glue down systems are highly resilient in water-prone environments. However, floating floors have a center fiberboard which can swell when they are exposed to water. As such, floating cork floors are not recommended for water-prone areas. When floating floors swell, the entire flooring needs to be replaced. Only the 100% cork tiles which are a glue-down product are recommended for any potentially wet areas.
If a flooding situation occurs where glue-down cork tiles have been installed, the standing water could possibly re-emulsify some of the adhesive and thus loosen a few tiles. These tiles can usually be dried out and reapplied with new adhesive after the subfloor has dried also.
