Standard Test Method for Determining Relative Humidity
(RH) in Concrete Floor Slabs Using in situ Probes
  • This test method covers the quantitative determination of percent relative humidity in concrete slabs.
  • This is the most common test in determining the moisture content within a concrete slab.
  • Testing process will require 2 trips to the site.
    • Day 1: Drill a 3/4" diameter hole to 40% slab depth and secure probe sleeve at each test site. This must take place a minimum of 24 hours prior to inserting probes.
    • Day 2: Insert probes, allow time for probes to equilibrate, record all readings.
Standard Test Method for Measuring Moisture Vapor Emissions Rate
(MVER) of Concrete Subfloor Using Anhydrous Calcium Chloride.
  • This test method covers the quantitative determination of the rate of moisture vapor emitted from bare concrete floors.
  • This is the second most common test for determining moisture content within a concrete slab.
  • Test process will require 3 trips to the site over 5 days.
    • Day 1: Removal of flooring & adhesive at each test site must be completed at least 24 hours prior to testing. (In the case of bare concrete, day 1 can be skipped)
    • Day 2: Lightly grind 20" x 20" area and placement of MVER kits at each test site.
      MVER kits must remain undisturbed for no less than 60 and no more than 72 hours.

      It is imperative these tests remain undisturbed & uncompromised for the duration.

    • Day 3 & 4: Test kits must remain undisturbed.

    • Day 5: Retrieval of MVER kits and recording results.
Standard Practice for Field Determination of Substrate Water Absorption
(Porosity) for Substrates to Receive Resilient Flooring.
  • This practice covers the determination of whether or not a substrate surface is considered porous or non-porous prior to installation of resilient flooring materials.
  • This is a relatively new standard that's slowly becoming more common.
  • Included with all testing at no extra cost.
Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring.
  • This practice covers the determination of the acceptability of a concrete floor for the installation of resilient flooring.
  • pH testing is no longer included in the  ASTM F 710 standard, however many flooring manufacturers still require pH testing prior to installation.
  • Included with all testing at no extra cost.
Standard Guide for Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter
  • Completely non-destructive however only provides readings to a depth of 0.5" - 1"
  • Only included upon request.
