Looking Beneath the Surface: Expert Reinforced Concrete Testing
We do accurate, non-destructive testing to figure out whether your reinforced concrete structures are up to scratch structurally and will last the distance. We find where the rebar is, take a look at the concrete strength, and give you the data you need to make a decision with confidence.

Do You Really Know What’s Inside Your Concrete?
Reinforced concrete is at the heart of modern concrete construction. Its performance depends on the bond between cement, aggregates, water, and embedded steel. If you cannot verify rebar location, cover depth, corrosion risk, or concrete strength, you are relying on an assumption rather than evidence.
That uncertainty can affect quality assurance, compliance with industry standards, and the service life of your structure.
At CBR Testing STS, we deliver specialist reinforced concrete testing and wider concrete testing services across the UK. Using innovative technology and UKAS-accredited testing methods, we assess both in situ concrete and extracted samples without unnecessary damage.
Our role is simple but vital:
- Test concrete accurately
- Determine mechanical properties
- Ensure safety and compliance
- Provide clear, actionable results
We support construction projects of all sizes, from refurbishment schemes to new-build developments.
Our Reinforced Concrete Testing Services
We provide a full range of reinforced concrete testing and construction materials testing services for fresh and hardened concrete.
1. Rebar Location, Mapping and Cover Surveys
Before you can start drilling, cutting, or coring, you need to know where the rebar is.
Using advanced cover meters and scanning kits, we:
- Locate and map the reinforcement inside your concrete elements.
- Work out the bar diameter
- Measure the concrete cover in line with the relevant BS EN standards.
- Identify any congestion before you do any structural alterations
This non-destructive testing approach keeps your structure safe and saves you the hassle of rebar strikes on site. It’s a vital part of refurbishment projects, structural modifications, and pre-demolition surveys.
2. Concrete Cover Depth and Carbonation Depth Testing
The cover on your concrete protects the embedded steel from corrosion. But if carbonation gets too far into the steel, then you’re in trouble, and that’s bad news for the structure.
We:
- Take a look at the carbonation depth on the site
- Work out how much effective cover you’ve got left
- Figure out the long-term risk to the structural integrity
- Have a look at any European standards and BS EN guidelines that might be relevant
- Report back with our findings and recommendations
Our carbonation and durability assessments help you come up with a plan for maintenance and extend the life of the structure.
3. Half-Cell Potential Testing for Reinforcement Corrosion
Reinforcement corrosion is a primary cause of deterioration in reinforced concrete.
Our half-cell potential testing:
- Assesses the probability of active corrosion
- Produces corrosion risk contour mapping
- Identifies high-risk zones before visible cracking or spalling
- Supports targeted repair planning
This allows you to manage in-place concrete proactively rather than reactively.
4. Concrete Core Sampling and Compressive Strength Testing
Where verification of structural capacity is required, we extract core samples for laboratory tests.
We:
- Safely drill and retrieve concrete samples
- Test compressive strength using calibrated compression machine equipment
- Assess density, bond strength, and other mechanical properties
- Compare results to the mix design specifications
All compressive strength test procedures are carried out to BS EN 12390 and other applicable standards.
Core testing allows us to determine actual concrete strength and confirm that the concrete meets project specifications.
5. Fresh Concrete and On-Site Testing
Quality control begins long before concrete reaches final strength.
We provide testing of freshly mixed concrete and fresh concrete mix at key stages of concrete construction.
Our on-site tests include:
- Concrete slump test to determine consistency
- Air content testing, including air-entrained concrete
- Temperature checks
- Sampling for the cube test and concrete cube casting
Fresh samples are transported to our laboratory for further analysis, including:
- Compressive strength test procedures
- Flexural strength and tensile strength testing
- Cement content verification
- Chloride content testing
- Chemical properties analysis
Testing both fresh and hardened concrete ensures your concrete mix performs as intended.
Comprehensive Construction Materials Testing
Concrete does not exist in isolation. Our wider construction materials testing services support full compliance on busy construction sites.
We assess:
- Surface hardness
- Compression forces under increasing load
- Flexural performance
- Mechanical and chemical properties
- Performance of specialist materials, including high-alumina cement
All laboratory tests are oven-dried and prepared in accordance with recognised methods to ensure accuracy and repeatability.
