NDTScan uses Wagner Meters for precise in-slab relative humidity testing in concrete flooring systems. These sensors help verify moisture conditions before floor coverings are installed, preventing adhesive failure, blistering, and long-term floor degradation. Wagner’s tools ensure our concrete inspections meet ASTM F2170 and British Standards for construction handover.
We deploy Wagner systems during floor prep, remediation, and pre-installation QA for residential, commercial, and industrial sites across the UK.

Why We Use Wagner
Wagner RH testing systems are quick to install, accurate over time, and easy to document. They reduce project risk and allow clients to meet warranty, QA, and compliance targets without delays.
Other Tools in Use
We pair Wagner with surface moisture checks from Protimeter where needed, but for internal slab RH validation, Wagner leads our testing protocol.
Moisture Risk Control in Concrete with Wagner Meters
At NDTScan, managing moisture in concrete slabs is a critical step in ensuring the long-term performance of flooring systems. We use Wagner Meters to assess in-slab relative humidity (RH) during construction, refurbishment, and floor installation workflows. Unlike surface moisture checks, which can be misleading, in-slab RH readings give us a true picture of the internal condition of the concrete — helping our clients avoid adhesive failures, delamination, blistering, and expensive rework.
Why In-Slab RH Testing Matters
Moisture issues are one of the most common causes of premature floor failure. Yet many contractors still rely on surface-level testing or environmental assumptions to determine readiness for coverings. That approach doesn’t work. The core of the slab can retain significant moisture long after the surface appears dry, particularly in fast-track builds or poorly ventilated areas.
Using Wagner’s in-slab sensors, we measure moisture levels where it counts — inside the slab. This gives our clients hard data on when the concrete is genuinely ready to receive resilient flooring, timber systems, or bonded finishes. With moisture-sensitive adhesives and floor coverings becoming more advanced (and more expensive), skipping proper testing isn’t just risky — it’s financially reckless.
Tested to Industry Standards
Our in-slab moisture testing procedures are fully compliant with ASTM F2170 and equivalent British Standards for construction and flooring installation. These standards define how and where sensors should be placed, how long the concrete should equilibrate, and what thresholds are acceptable before installation can proceed.
By aligning with these protocols, we help clients:
-
Prove due diligence in QA and warranty documentation
-
Avoid conflicts between installers, specifiers, and main contractors
-
Support manufacturer compliance requirements
-
Provide traceable data for future audits or handover packages
Our RH testing services are used across commercial, residential, industrial, and public sector projects — from high-end housing and school refurbishments to airport terminals and healthcare buildings.
Where Wagner Makes a Difference
Wagner Meters’ technology allows for rapid, accurate, and cable-free testing, which is a major step forward from legacy RH systems. Their embedded Rapid RH L6 sensors are installed directly into pre-drilled sleeves in the slab, where they equilibrate with the concrete’s internal humidity. Once stabilised, the readings are wirelessly captured using Wagner’s Smart Reader and logged in the DataMaster L6 app.
There’s no tangled wiring, no connector failures, and no tedious data entry. Each sensor is individually tagged, and all readings are timestamped, geolocated, and exported as formal reports — giving contractors, installers, and specifiers the confidence that moisture thresholds are being met across the site.
Real-World Use Cases for Wagner Meters
1. Commercial Fit-Out Projects
Fast-tracked office fit-outs often demand aggressive flooring schedules. We use Wagner Meters to confirm whether newly poured slabs are ready for floor covering or require further drying time. In many cases, our early detection of high RH has helped project teams re-sequence works, avoiding costly floor uplift or warranty breaches later on.
2. School Refurbishments and Public Buildings
Older concrete slabs can retain hidden moisture after decades of service. We conduct moisture verification before vinyl, LVT, or sports flooring is installed in educational buildings — helping local authorities and FM providers meet both H&S and performance standards without guesswork.
3. High-End Residential Developments
Moisture-sensitive hardwood or engineered timber floors demand precise control of in-slab RH. Our testing ensures compliance with strict installation parameters, especially where underfloor heating is involved or bespoke finishes are specified.
4. Industrial and Warehouse Facilities
In heavy-use environments like logistics centres and production floors, slab moisture can affect the performance of epoxy coatings, resin floors, or expansion joints. We validate slab condition before surface preparation begins, reducing the risk of blistering or bonding failure under service conditions.
Data That Delivers Confidence
One of the major advantages of using Wagner Meters is the quality and usability of the data. The DataMaster L6 app syncs instantly with the field sensors, capturing a complete dataset for each reading — including:
-
Sensor ID
-
Timestamp
-
RH percentage
-
Temperature
-
Location within the building
This ensures full traceability and simplifies report generation for QA managers, consultants, and flooring contractors. All data is exportable as shareable PDFs or CSV files, which can be appended to project documentation, O&M manuals, or building control packages.
Cost-Efficient and Reusable Systems
Wagner’s testing platforms are designed for efficiency. The embedded sleeves are reusable, allowing multi-phase projects to test repeatedly without needing full sensor replacement. This significantly reduces cost over the life of a project and supports ongoing moisture monitoring if phases are handed over incrementally.
For large schemes or block-by-block refurbishments, this reuse model is ideal — giving us the flexibility to test dozens of locations quickly, without adding labour-intensive site prep or wasteful material costs.
Streamlined Workflows for Project Teams
We know that time on site is tight. Our approach with Wagner Meters to in-slab RH testing is engineered for speed and minimal disruption. We coordinate with site managers and trades to install sensors at the right time — usually during early M&E or screed preparation — and schedule readings just prior to floor covering installation.
This proactive workflow ensures that flooring contractors aren’t delayed by last-minute testing or held liable for unknown moisture conditions. It also allows project managers to slot moisture verification into their critical path scheduling, improving delivery certainty.
Training and Collaboration with Installers
We don’t just drop sensors and disappear. Our team works closely with flooring installers and QA supervisors to explain results, compare to manufacturer thresholds, and interpret any borderline readings. If RH levels are above tolerance, we advise on drying strategies, ventilation, or heating adjustments to accelerate curing safely and effectively.
Our collaborative approach and use of Wagner Meters has earned the trust of many fit-out contractors and building envelope specialists — helping reduce friction between trades, consultants, and clients at the handover stage.
Part of a Broader Moisture Testing Strategy
While Wagner Meters provides the foundation of our in-slab RH strategy, we supplement this with surface moisture testing using Protimeter or Tramex systems when needed. This is particularly useful when assessing slab edges, small pour areas, or legacy flooring that may have multiple substrate types.
We also provide relative humidity and dew point monitoring for ambient conditions — supporting climate-sensitive installs and helping clients understand whether environmental controls are affecting slab drying.
