Xps Under Slab Insulation

I understand the qualities of each regarding water absorption and drying out but would it xps particularly affect the long term performance to the point where the slab is compromised.

Xps under slab insulation.

Insulation under concrete floor slab is often desirable for commercial buildings such as warehouses and factories which are being designed to. Moisture resistance is also important for belowgrade and under slab insulation since wet products provide much lower thermal resistance. Their researchers found that xps insulation installed below grade for 15 years had absorbed 67 percent or more moisture. Below grade under slab system with foamular extruded polystyrene rigid board insulation and radiant heating.
