Excess moisture in concrete slabs is a primary cause of flooring catastrophe. The problem is completely avoidable and yet costs billions of dollars annually.
When flooring fails, damages are incurred for downtime, repair, and replacement. This problem isn’t geographical in nature nor limited to humid climates. Rather, it’s a widespread issue triggered by a failure in overall construction and scheduling.
Flooring problems can be the result of failure in accomplishing the following:
Some of the problems that arise as a result of installing flooring before the concrete slab is properly dried include:
Warranties on many types of flooring are conditional upon the concrete slab being properly cured and cleaned. Most manufacturers of flooring stipulate that warranties can be voided if moisture tests aren’t conducted on the slab before installing their products.
There are many types of tests which are used to determine the moisture content in concrete, such as the calcium chloride test, which is widely accepted for measuring dynamic moisture. The calcium chloride test has been used in the construction industry for decades, but it is an inferior method as compared to the use of the latest technology in moisture meters.
Many of the methods for obtaining concrete moisture readings measure surface humidity and not the dynamic moisture condition. The moisture in concrete slowly migrates to the surface, and the best way to get a reliable reading which takes migrating moisture into account is a relative humidity (RH) test.
Using the most accurate means available for determining the moisture content in the slab is essential. Failing to get an accurate measure of the moisture level in the concrete can lead to premature installation of the flooring, which may result in a flooring failure.
The most reliable RH test, which provides dependable readings and is superior to all other humidity measurement systems on the market, is the Rapid RH 4.0 system. It’s cost-effective and can ultimately save thousands of dollars in the litigation and repair that result from failing to get an accurate reading of the moisture content in the slab.
When flooring installation is delayed, awaiting proper moisture levels in the slab, the advanced technology of Rapid RH 4.0 simplifies the process of monitoring the moisture levels in the slab.. Once the Rapid RH 4.0 sensors are properly installed, anyone on the construction site can obtain the moisture readings.
