Concrete Deck RH Testing
ASTM-Standard Testing to Confirm Your Concrete Deck is Ready for Roofing
Concrete Deck Relative Humidity Testing uses probes to measure moisture inside the concrete slab. It reveals the internal condition rather than a surface reading so you can decide whether to proceed or mitigate.
Installing over a damp deck can cause:
- Adhesive and coating failures
- Blistering or delamination of roofing materials
- Premature deterioration of insulation or fasteners
- Mold growth, leaks, and warranty disputes
When to Perform RH Testing
- New Construction: Confirm deck dryness before installing adhered membranes or vapor-tight systems.
- Re-Roofing: Validate conditions after deck repairs or partial replacement.
- Moisture-Sensitive Projects: Healthcare, education, labs, and other facilities where failures carry high cost.
- Suspected Moisture Issues: When decks show discoloration, slow cure times, or evidence of past leaks.
How We Test
We follow ASTM requirements for relative humidity testing in concrete decks. Our team installs probes below the surface to measure internal moisture, then compares readings against environmental conditions. Results are compiled into a clear, professional report with data and photos.
What You Receive
- Relative humidity results by location and deck section
- Analysis of overall moisture condition
- Reporting that supports warranty and code submittals
Benefits
- Accuracy: Probes reveal true internal deck moisture, not just surface readings.
- Risk Control: Prevents failures caused by trapped moisture.
- Cost Savings: Avoids expensive tear-offs and change orders.
- Documentation: Provides ASTM-compliant data for owners, contractors, and manufacturers.
Structura View’s process is methodical, ASTM-compliant, and supported by clear reporting that helps owners, contractors, and manufacturers understand deck moisture condition.
