Wagner Rapid RH 4.0 EX Concrete Testing

The single-use Rapid RH® 4.0 EX gives flooring and building professionals the concrete moisture data they need to meet ASTM F2170 standards.

Any complete floor system will generally consist of several “layers” that may or may not be composed of the same building material. Concrete slabs can form the foundation for wood, tile, terrazzo, bamboo, vinyl or carpet floors. Wooden subfloors support residential and office floor systems. Adhesives of various types provide the bond between layers. In every situation, the long-term success or failure of a floor rests on accurate moisture content management, and knowing how each strata of the floor system interacts with moisture.
