Still getting relative humidity (RH) reading of 99%. What to do?

Geographic Location

  • Humid regions can influence the relative humidity (RH) in concrete
  • Room’s with high humidity make it difficult for moisture to escape concrete
  • Room’s humidity will equalize without HVAC running well

Date that the Slab was Poured

  • Fresh slabs take longer to dry out (ideal conditions: 1 month for every inch)
  • Moisture can penetrate through the bottom of concrete
  • Older pours might not have a vapor barrier

Room Does Not Have HVAC Running

  • HVAC systems pull small amounts of moisture out of a room
  • Mitigation services specialize in pulling large amounts of moisture out of rooms
  • HVAC systems are important when heating up a room
  • Moisture likes to leave concrete when the air is warmer than the slab

Room is Colder than Concrete Slab

  • Moisture will stay in the concrete if the slab is warmer than the air

You may want to look into Moisture Mitigation. It can be time-consuming and costly.
