Moisture & Failure Analysis
Scientific Moisture Diagnostics & Failure Analysis
Moisture is the #1 cause of flooring failures. Our ASTM-compliant moisture testing and failure analysis identifies the source, measures the severity, and documents the evidence needed to resolve disputes, support claims, and prevent future failures.
Moisture is responsible for more flooring failures than any other single cause. Hardwood cups, crowns, and buckles. LVP and SPC floors separate and lift. Laminate swells and peaks. Tile debonds and cracks. Adhesive fails. In nearly every case, the root cause is moisture — but identifying the source requires specialized testing and analysis.
My Floor Inspection Inc. conducts ASTM-compliant moisture testing and forensic failure analysis using calibrated professional equipment. We test concrete slabs for relative humidity (ASTM F2170) and moisture vapor emission (ASTM F1869). We measure wood moisture content with pin and pinless meters. We use thermal imaging to detect hidden moisture. Our findings are scientifically defensible and accepted by manufacturers, insurance companies, and courts.
What We Do
Moisture Analysis Services
Moisture Intrusion Investigations
We identify the source of moisture causing flooring damage — whether it's a plumbing leak, hydrostatic pressure through a concrete slab, vapor diffusion, condensation, humidity imbalance, or water intrusion from exterior sources. We trace moisture to its origin.
Concrete Slab Moisture Testing
ASTM F2170 in-situ relative humidity probe testing and ASTM F1869 calcium chloride moisture vapor emission rate testing. These are the industry-standard tests required by virtually all flooring manufacturers for concrete slab moisture assessment.
Hardwood Moisture Diagnostics
We measure wood moisture content using calibrated pin-type and pinless moisture meters, map moisture gradients across the floor, and compare readings to subfloor moisture levels to identify the source of hardwood failures like cupping, crowning, and buckling.
Flooring Failure Analysis
Comprehensive analysis of flooring failures to determine root cause. We evaluate material condition, installation quality, subfloor preparation, moisture conditions, and environmental factors to determine why the flooring failed.
Substrate Evaluations
We evaluate the condition and suitability of substrates including concrete slabs, wood subfloors, and underlayments. Substrate conditions — flatness, dryness, structural integrity — are critical to flooring performance and often the hidden cause of failures.
ASTM-Compliant Testing
All moisture testing is conducted in accordance with published ASTM standards including F2170 (Relative Humidity in Concrete Floor Slabs), F1869 (Moisture Vapor Emission Rate), and F710 (Preparing Concrete Floors for Resilient Flooring). Our testing protocols meet manufacturer requirements.
Why This Matters
Moisture testing is not optional — it is required. Virtually every flooring manufacturer specifies moisture testing before installation, and ASTM F2170 and F1869 are the industry-standard test methods. Without proper moisture testing, warranty claims can be denied, insurance claims can be rejected, and installation disputes cannot be resolved. Our testing meets these standards, and our reports are accepted by manufacturers, insurers, and courts.
Our Process
How It Works
Site Assessment
We assess the site conditions, review the flooring system, identify visible symptoms, and determine which moisture tests are appropriate for the situation.
ASTM Testing
We conduct ASTM-compliant moisture testing using calibrated professional equipment — including F2170 RH probes, F1869 calcium chloride kits, wood moisture meters, and thermal imaging as needed.
Failure Analysis
We analyze the test results alongside installation assessment, material evaluation, and environmental conditions to determine the root cause of the flooring failure.
Diagnostic Report
We deliver a detailed report with all test data, moisture maps, photo documentation, root cause analysis, and recommendations — formatted for dispute resolution, warranty claims, or litigation.
Questions & Answers
Frequently Asked Questions
What is ASTM F2170 testing?
ASTM F2170 is the standard test method for measuring relative humidity in concrete floor slabs using in-situ probes. It measures the moisture condition deep within the concrete slab, which is the most accurate indicator of whether a concrete subfloor is suitable for flooring installation. This test is required by virtually all flooring manufacturers.
What is ASTM F1869 testing?
ASTM F1869 is the standard test method for measuring the moisture vapor emission rate (MVER) of a concrete subfloor using calcium chloride test kits. It measures how much moisture vapor is being emitted from the concrete surface. Together with F2170, these are the two industry-standard tests for concrete slab moisture assessment.
Can moisture testing identify the source of water damage?
Yes, in many cases. We use moisture meters, thermal imaging, and site investigation to trace moisture to its source. Common sources include plumbing leaks, concrete slab moisture vapor emission, hydrostatic pressure, condensation, high indoor humidity, and water intrusion from exterior sources. Identifying the source is essential for resolving insurance claims, warranty disputes, and contractor conflicts.
How long does moisture testing take?
ASTM F2170 RH probes must remain in place for 24 hours to obtain accurate readings. ASTM F1869 calcium chloride tests must remain in place for 60-72 hours. We conduct all testing on-site and deliver results in a comprehensive report within 5-7 business days of completing the tests.
Why is moisture the #1 cause of flooring failures?
Flooring materials respond to moisture in predictable ways. Hardwood absorbs moisture and expands, causing cupping, crowning, and buckling. LVP and SPC floors expand and push against walls, causing separation, peaking, and lifting. Laminate absorbs moisture at joints, causing swelling and peaking. Tile can debond when moisture affects the adhesive or substrate. Moisture is the hidden variable in the vast majority of flooring failures.
