A proactive approach will save the involved parties from the hardship of product dissatisfaction or failure. Whether in design implementation, product specification or troubleshooting, we provide expert advice forthe entire project from start to finish. In our consulting approach, we research and consult on the following:
Do you require a review of aspecified product? We can evaluate the manufacturer’s specifications and make sure they are appropriate for the intended use.
Industry installation guidelines
We can verify that the manufacturer’s installation guidelines are being followed. Has the subsurface been tested for moisture? - Is the job site ready for finished flooring? We will measure, log and record temperature and humidity readings prior to, during and after the installation. We provide useful data, you make an informed decision. We will examine substrates, areas, and conditions, for compliance with requirements for maximum moisture content, installation tolerances, and other conditions affecting performance of work. For the record, prepare written report, listing conditions detrimental to performance of work.
Verify that concrete slabs comply with requirements for installation of floor covering according to ASTM F 710. Verify that substrates are dry and free of curing compounds, sealers, and hardeners. Verify that substrates are dry according to test methods recommended by flooring manufacturer.
In testing moisture in concrete floors we use the following tests:
- Electrical Resistance Test: to determine concrete moisture content
- Electrical Impedance Test: to determine concrete moisture content
Quantitative Anhydrous Calcium Chloride Test- standard test method for measuring moisture vapor emission rate of concrete slabs
Relative Humidity/Hydrometer Test- standard method for determining relative humidity in concrete floor slabs using IN-Situ Probes
ASTM F710 pH Test
Standard practice for preparing concrete floors to received resilient flooring
ASTM F710 - 08 Standard Practices for Preparing Concrete Floors to Receive Resilient flooring
“A permanent, effective moisture vapor retarder, of the specified thickness and permeance, is required under all on- or below-grade concrete floors. Concrete floors for resilient floorings should be permanently dry, clean, smooth, structurally sound, and free of substances that may prevent adhesive bonding. Surface cracks, grooves, depression, control joints or other non-moving joints, and other irregularities should be filled or smoothed with latex patching or a recommended underlayment compound. The surface of the floor should be cleaned by scraping, brushing, vacuuming, or any other method. All concrete slabs should be tested for moisture regardless of age or grade level, while all concrete floors should be tested for pH before installing resilient flooring.”
