Moisture in Concrete Floors and the Impact on Flooring Systems
Concrete slabs are the most common flooring base used in a range of buildings, including residential and commercial. Like the majority of building materials, concrete constantly interacts with the conditions around it – temperature, humidity and other factors all have an impact on the moisture levels in concrete. Excessive moisture from floor slabs after installation can cause floor covering system failures such as:
- Debonding of coatings
- High pH attack on floor finishes
- Microbial growth
- Release of adhesive
- Flooring expansion
If high moisture emission is discovered during moisture testing, then proper precautions should be taken to prevent flooring system failures.
Kinetex textile composite flooring will perform in elevated RH slabs up to 95% using Kinetex Adhesive and up to 99% when using PreFix. The breathable nature of this product allows moisture to pass through the backing rather than trap it underneath. This method of vapor transmission allows Kinetex to be installed without costly moisture mitigation as long as the Relative Humidity Test reads 95% or below (99% using PreFix).
