Calcium Chloride Concrete Moisture Test - Dome Kit ASTM Method Orange CCMTK

Calcium Chloride Concrete Moisture & Alkalinity (pH) Test Kit from Vapor Score  ASTM Method

Calcium Chloride Tests - also called the dome test - are designed to measure the moisture vapor emission rate of concrete subfloors using anhydrous calcium chloride. 

The calcium chloride test kits can determine whether or not there is a moisture problem and will allow the contractor/installer to fix this before it becomes a flooring issue. 

In addition, a  concrete moisture test kits includes a pH test kit to measure the concrete alkalinity at the surface.

Vapor Score Calcuim Chloride Test Kits meet anc comply with both ASTM F1869 and ASTM F710-11. Test used to measure the vapor emission rate of your concrete slab and its acceptability of floor coverings. 

Standard Test Method for Measuring Moisture Vapor Emission Rate (MVER) of Concrete Subfloor Using Anhydrous Calcium Chloride - Moisture vapor emission rate (MVER) is the amount of water vapor in pounds emitted from 1000 sq ft area of concrete flooring during a 24 hours period. This number or figure corresponds to flooring manufactures acceptable tolerance.

This method has and is the industry standard. Calcium Chloride Test Kits allow you to achieve a quantitative figure which will coincide with floor manufactures requirements.

Please note: The measurements obtained by utilizing Concrete Moisture Test Kits only reflect the current condition of the concrete.

The Concrete Moisture Test Kits' results will reflect a figure of weight in pounds of water evaporation emitted from 1000 sq ft over a 24hr period. The test must be done when the building is at the same temperature and humidity.

Building Condition's as per ASTM F1869 allows for test conditions to between 65°F and 75°F and 40% and 60% relative humidityThese requirements need to be sustained for 48 hours proceeding to and during the test.

The F 1869 method calls for cleaning a 20-inch-by-20-inch square at each test site to be sure you are testing bare concrete. This will remove curing compounds, sealers or old adhesive residue. The people who do testing for a living always grind the surface so the slab is completely clean. Failure to clean the slab may result in a false low reading.

ASTM F 1869 calls for a 24-hour waiting period after cleaning before the test kit is placed so surface moisture that was trapped beneath whatever coating was there can evaporate. Failure to wait 24 hours may result in a false high reading.

ASTM F1869 calls for 3 tests for the first 1000sq ft and 1 test for each 1000 sq ft. after that. 

Why Test For Moisture?

Concrete Slab Moisture can cause problems with adhesion of floor-covering material, such as tile, sheet flooring, or carpet and bond related material failure of non-breathable floor coverings.

Many adhesives used for installation of floor coverings are more water sensitive than in the past, due to restrictions on the use of volatile organic compound (VOCs).

Sources for Moisture

- Condensation

- Moisture migration through the slab from wet soil under the slab

- Broken or leaking pipes buried below or in the concrete

- Surface water from leaks or flooding collecting on the concrete

Problems Associated With Moisture

- Inadequate bond

- Moisture prevents or retards setting of water-based adhesives

- Weakening of the bond of previously set adhesives

- Growth in tile resulting in peaked joints or curled tile

- Discoloration

- Salt (alkali) deposits at tile joints

- Blisters in sheet flooring installations (When blisters form immediately after installation, they are normally associated with air. When a period of  time passes before blisters form, they are usually a result of moisture in the slab.

- Bleeding of adhesive through the joints of tile

- Shifting Tile
