|The Bell Flooring Sciences Group provides nationwide consulting, project management, inspection, and testing services for the floor covering and coating industries along with others in the construction and real estate industries. Our clients include flooring contractors, installers, retailers, general contractors, architects, designers, developers, building owners & management companies, tenants, homeowners, manufacturers, distributors, attorneys, disaster restoration contractors, and insurance companies.
The Bell Sciences Group Principal Consultant W Bell is a member of various technical and education committees that and oversee many of the industry standards, test methods, and guidelines regarding concrete related issues with floor coverings and coatings including ASTM International, International Concrete Repair Institute (ICRI), and The Society for Protective Coatings (SSPC).
Some of our testing services include:
MOISTURE & ALKALINITY TESTS
Relative Humidity (RH) in Concrete Floor Slabs
ASTM F2170-02 Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In-Situ Probes.
Relative Humidity (RH) on the Surface of Concrete Floor Slabs
ASTM F2420-05 Standard Test Method for Determining Relative Humidity on the Surface of Concrete Floor Slabs Using Relative Humidity Probe Measurement and Insulated Hood.
Concrete Moisture Vapor Emission Rate (MVER)
ASTM F1869-04 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloors Using Anhydrous Calcium Chloride.
Alkalinity (pH) Level on the Surface of Concrete Floor Slabs
ASTM F710-03 Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring specifies that the surface of concrete slabs be tested for alkalinity before installing a floor covering. Our agency uses both pH meters and pH indicator paper to perform this test.
