A most unfortunate flooring failure!

I have had my Rapid RH Meter for about 5 years, and I love having it at my disposal, but realistically as an installer, we don't get paid to leave one jobsite in one area of the city to go spend a half a day testing in another area of the city. There is a cost involved in testing concrete moisture. Sure, all the purists can say that the cost of doing or sending someone to do a moisture test (along with the cost of the sensors, etc,) is akin to purchasing an insurance policy on the installation, if it's not in the bid spec, you are incurring higher costs than the competition you're bidding against. As an installer, why would you spend an additional $60-80 on sensors and a half a day of downtime to go and test a jobsite before the installation date? Installers are already on the lowest end of the flooring pay scale and are the least able to take the hit. Until moisture testing is clearly written into the general contractor's scope of work, it will continue to be hit-and-miss. If I have a job larger than about 2000-3000 square yards, I will do the testing myself at no charge for my own peace of mind, but there is a profitability cut-off that I have to realistically respect.

This thinking just blows my mind.

As an installer, you are supposed to verify you are installing according to the product specs. You are supposed to use the correct adhesive trowel. You are supposed to allow the flooring to acclimate. You are supposed to install within a specified range of temperature and humidity.

It takes less than 10 minutes to install a Wagner probe. And about 10 seconds to read one.

I can tell you that if you have a floor fail due to moisture or alkalinity and you installed it without following the manufacturer's specifications you can be deemed liable for the failure.

Installers have to verify the concrete meets specs before installing the flooring. That's their job as the flooring professional.
