How do I know if my Austin slab has a moisture problem?

The only reliable way to know is to test. A calcium chloride test or in-situ relative humidity probe test will give you a quantitative moisture reading that can be compared against the manufacturer's specifications for your chosen flooring product. Visual inspection is not sufficient, as slabs that appear dry can still be transmitting moisture at harmful rates.

Can I install hardwood over a concrete slab in Austin TX?

Yes, but it requires proper moisture testing and, in most cases, a moisture mitigation system. Solid hardwood over concrete in Austin almost always requires a moisture barrier. Engineered hardwood over concrete may or may not require a barrier depending on the slab moisture reading and the product specifications.

What is the difference between a moisture barrier and a vapor barrier?

The terms are often used interchangeably, but technically a vapor barrier is a material with very low permeance that stops virtually all moisture vapor transmission, while a moisture barrier or vapor retarder allows some moisture to pass through but at a controlled rate. For most flooring applications, a vapor retarder is sufficient. True vapor barriers are used in below-grade applications.

Does LVP need a moisture barrier over concrete in Austin?

Check the manufacturer's specifications for the specific product you are using. Glue-down LVP requires an adhesive system that is compatible with the slab moisture level.
