SECTION 09 0565

MOISTURE TESTING FOR FLOORING INSTALLATION

placement of the test kits. Testing when floor coverings have never been installed may waive the 24 hour wait period.

D. Minimum number of tests: For Moisture Vapor Emission Rate, Relative Humidity and pH testing, provide three for the first 1,000 square feet of floor area, and at least one for each additional 1,000 square feet or fraction thereof.

3.2 MOISTURE VAPOR EMISSION TESTING (MVEP)
A. MVEP testing shall be performed in accordance to ASTM F1869.

B. Unless more stringent requirements are recommended by flooring manufacturer, the maximum allowable moisture release at time of flooring installation shall be three pounds per 24 hours per 1,000 square feet.

C. Weigh test dish on site prior to start of test. S cale must report weight to 0.1 grams. Record weight and start time. Expose Calcium Chloride and set dish on concrete surface. Install test containment dome and allow test to proceed for 60 – 72 hours.

D. Retrieve the test dish by carefully cutting throu gh containment dome. Close and reseal test dish. Weigh test dish on site recording weight and stop time. Calculate and report results as "pounds of emission per 1,000 sq. ft. per 24 hours".

E. In the event the MVEP value exceeds the value spe cified in this Article and the flooring manufacturer recommended limits, CONTRACTOR shall p ropose remediation to OWNER. In new concrete slab construction, remediation shall be at no cost to OWNER.

3.3 RELATIVE HUMMIDITY TESTING
A. Relative humidity testing shall be performed in conformance to ASTM F2170.

B. Choose test areas where high moisture levels are suspected. Holes in new concrete slabs may be cast or drilled. Depth of holes shall be 40% of slab thickness for slabs drying only from the top, and 20% when drying from top and bottom, as indicated on ASTM F2170. Determine the concrete thickness of each type of slab to be tested and calculate depth of holes.

1. Hole shall be drilled dry; do not use water for c ooling or lubrication. Drill holes in the concrete and insert test liners. Hole shall not be more than 0.04 inches, or one millimeter, larger than the test liner.

2. Before placing concrete, secure liner tube to for mwork or steel reinforcing to avoid displacement during concrete placement, conso lidation and finishing.

Secure a solid rod into the liner and protruding slightly above the top of the liner to exclude fresh concrete from entering the liner.

C. Clean the area around the hole with a vacuum clea ner and vacuum the dust out of the hole. Immediately, set the sleeve by tapping the sleeve into the hole with a hammer or mallet.

SECTION 09 0565

MOISTURE TESTING FOR FLOORING INSTALLATION

D. Remove the sleeve plug and place probe into the s leeve assuring that it reaches the bottom of the test hole. Connect the probe lead wire to the meter, and turn meter on.

Allow time for the probe to sit in the test sleeve to achieve moisture equilibrium before taking relative humidity readings. Probe shall be at the same temperature as the concrete before the reading. Check for drift and f ollow meter manufacturer recommendations.

E. Record the relative humidity to the nearest perce nt and temperature to the nearest degree. Record location of hole within the structure and depth of probe. Use the relative humidity probe to measure the ambient air temperature and relative humidity above the slab in the vicinity of the test location. Remove the liner and fill the hole with a cementitious patching compound.

F. In the event the relative humidity exceeds 75% an d the flooring manufacturer recommended limits, CONTRACTOR shall propose remediation to OWNER. In new concrete slab construction, remediation shall be at no cost to OWNER.

3.4 PH LEVEL TESTING
A. Perform testing in accordance to ASTM F710, and a t the same time as the vapor emission and relative humidity tests.

B. Place several drops of water onto the concrete su rface to form a puddle approximately 1” in diameter. Allow the water to set for 60 +/- 5 seconds. Dip the pH paper into the water and remove immediately, compare color to chart provided by paper supplier to determine pH reading. Record and report results.

C. When using pH Pencil and pH Meters, follow the in strument manufacturer’s instructions.

D. The surface of the concrete should have a pH of 9 or less. In the event the pH exceeds this value and the flooring manufacturer recommended pH limits, CONTRACTOR shall propose remediation to OWNER. In new concrete slab construction, remediation shall be at no cost to OWNER.

3.5 BOND TEST
A. Perform bond testing in accordance to ASTM D4541 or per manufacturer’s recommendations.

B. Select appropriate locations for the bond tests s uch as near walls or in light traffic areas.

Spaced test samples approximately 50 feet apart throughout the designated installation area. Number of tests will be as determined by the recommended spacing of 50 feet.

C. Use the flooring material and recommended adhesiv es. Install 3' x 3' panels using the exact techniques that will be used for the flooring installation. It is recommended that tests be spaced approximately 50 feet apart throughout the designated installation area.

Tape edges of panels to prevent edge drying of adhesive. Protect test panel from traffic.

D. After 72 hours of placing the flooring, remove ta pe and observe whether it is bonded tightly to the floor, by trying to lift the edges with a scraper or other means, or pull flooring from the subfloor by hand. Determine if bonding is suitable for flooring installation.

E. At locations where membrane, primer, leveler or p atch are applied, perform applicable bond testing recommended by flooring manufacturer to assure adequate bondage of flooring to substrate.

F. Success or failure shall be determined by visual interpretation and the amount of physical effort required to remove the floor covering. If the flooring material can be removed it will indicate failure of the bond test. If the flooring requires a great deal of effort to pull it up, the bond test can be considered successful, providing no sign of moisture is found. In the event that bond failure occurs in new concrete slab construction, remediation shall be at no cost to OWNER.

3.6 CLEAN UP
A. Remove rubbish, debris and waste materials and le gally dispose of off the Project site.
