Moisture In Heritage Plank Floors


We are having trouble with the heritage plank floor we bought from carpet mills of america. Their inspector tells us that we have a moisture level of 5.? in our foundation. The planks are coming unglued and the edges on several planks are scalloping. No one ever tested our floor before it was installed to tell us we had moisture in our foundation. When it was installed the installers had to level the floor in several places and within a few hours were installing the planks right on top of it. Others we talked to that had wood floors installed could not even walk on the leveled floor for 24 hours or more. We have $11,000.00 of wood flooring in our home and we are very sick about it. Please let us know what we can do to get our on professional inspection and what if any thing we can do.

Dear Steve and Kathy

I’m so sorry to hear of your troubles. But this is a fairly easy one. The 5 the inspector came up with should be 5 on the Tramex Concrete Moisture Encounter meter. It’s a small hand held meter that has probes that are is pressed to the concrete floor. The highest reading allowed for wood is 4 1/2. And if a reading over 4 is detected many more readings should be done, in the wettest season you have. Oh, of course that needs to be done BEFORE they even consider selling you any type of wood floor.

Along with this test they could have done a Calcium Chloride moisture emissions test. This test is a little more tricky, but basically it involves taping down a bubble container to the floor with a sample of pre-measured Calcium Chloride in the bubble. After a certain length of time this sample is sent back to the testing company, and they send back the results. A 4 in this case is the maximum pounds per 1000 square feet over 24 hours, allowed for wood floor installation. This is a better

So you see in either case you have exceeded the maximum, and hence the bad result. The solution is clear, remove all the hardwood ( you didn’t say of this was solid wood or engineered) clean up the subfloor. And install carpet. You can never have a hardwood floor in that present situation. Don’t be too alarmed by the high readings, all concrete floor emit some moisture, it’s just too high for wood and all vinyl products.

Now if you are going to ask me, who is to blame. Well, after 3 court cases, (the last one is described in the Wrong Way Floor in the Case in Point section) I would believe that it is up to the flooring contractor to determine what wood floor, and what method of installation is best in your situation. It is always up to the expert to do all tests, and if they did not they will be responsible for returning to the point at which this all began. Plus maybe punitive damages, and costs of the inconvenience of the first job. And the cost of moving out while they remove and CLEAN the concrete, install new carpet, and you restore your life. Please don’t be sick, just get this sorted, I’m sure a large (at least they sound large) company is not will to risk bad publicity even on a job this size.

I just completed a long article on this very subject, wood floors on concrete, and you will see it in the site in the next month or two. It deals with all these problems, moisture, leveling, and picking the right installation method.

As always your Most humble servant, Joseph, the Wood Floor Doctor.
