RH 78.2% · 72.1°F
Concrete moisture, measured and documented.
EYLARK combines flooring inspection expertise with concrete moisture testing, field diagnostics, and forensic documentation — performed with an understanding of both the concrete substrate and the flooring system involved.
Concrete moisture testing
ASTM F2170 drilled RH probes and ASTM F1869 calcium chloride testing, documented at the tested locations.
Moisture mapping
A grid survey of the whole floor that shows where moisture is concentrated and where to test.
Water damage moisture testing
After a leak or flood: map the water, verify drying, and document recovery.
Floor readiness
Confirm the slab meets the new flooring and adhesive moisture limits before installation.
Concrete can look dry and still hold moisture.
Concrete can appear dry while still containing moisture conditions that affect flooring and adhesives. EYLARK provides professional ASTM moisture testing, analysis, and documented findings before installation.
In-Situ Relative Humidity Testing
Measures moisture within the concrete slab at depth, using installed probes.
Pricing in your testing plan
Calcium Chloride Testing
Measures moisture vapor emission from a prepared bare concrete surface.
Pricing in your testing plan
A combined moisture picture
Using both methods can provide additional documented information about moisture within the slab and vapor emission from the surface.
Know the slab before you install.
Moisture hides in looking-dry slabs
A surface that appears dry can still contain moisture conditions that affect adhesives and flooring performance.
Documented, not assumed
Testing documents the moisture conditions at the tested locations and allows comparison to the applicable product or system requirements when available.
Before the install, not after
Testing before installation helps inform decisions — and creates a record that can support a later concern or claim.
Evidence over assumption.
Fully independent
EYLARK sells no flooring, adhesives, or mitigation products. The only product is a defensible reading of the slab.
Method-led testing
Testing follows published ASTM procedures, with locations and conditions documented for each project.
Clear, documented reports
You receive a professional certified report with scope, methods, locations, conditions, and stated limitations.
