CONCRETE MOISTURE TESTING SERVICES

Moisture-related floor covering failures are responsible for over $1 billion annually in damages. The problems range from cupping, buckling, blistering and adhesive failure to discoloration, IAQ issues and mold growth. These issues can occur soon after the installation, and in some cases years down the road. Additionally, moisture testing of slabs is a key component of many manufacturers warranty requirements.

Two of the more common moisture testing methods in use today when installing resilient flooring are:

• Anhydrous calcium chloride test (ASTM F710 standard)
• Direct reading relative humidity probe (ASTM F2170 standard)

The relative humidity probe measurements are quickly becoming the state-of-the-art for investigations, but it is important to review the manufacturers recommendations on which standard is recognized for warranty purposes. ACC is equipped to perform both types of testing.
