About the Service

What is a Hardness Test?
And What Does It Measure?

A Hardness Test is a non-destructive method for evaluating the surface hardness of materials such as concrete and structural steel directly on-site. Using calibrated hardness testing instruments, the test delivers precise hardness values that can be correlated to compressive or yield strength — providing critical data for structural assessment, quality control, and material acceptance.

Hardness Testing delivers reliable material data without surface damage: accurate hardness values with strength correlation, suitable for both concrete structures and steel components — ideal for existing building assessment, quality control, and material investigation.

What Hardness Test Measures

Calibrated on-site hardness testing for concrete and steel — delivering reliable hardness values, strength estimates, and detailed inspection reports for every project.

Concrete Hardness Testing
Using rebound hammer or digital hardness instruments to evaluate concrete surface hardness and estimate in-situ compressive strength — without drilling or coring.
Steel & Metal Hardness Testing
Portable Leeb or UCI hardness testers for structural steel, welds, and metal components — delivering Brinell, Vickers, or Rockwell equivalent values on-site.
Strength Correlation & Analysis
Converting measured hardness values to estimated compressive strength (concrete) or yield/tensile strength (steel) using recognised engineering correlations and calibration curves.
Multi-Point Grid Testing
Systematic grid-based testing across large surfaces to map hardness variation, identify weak zones, and produce spatial hardness distribution data for the full structural element.
Non-Destructive Method
No drilling, cutting, or surface damage — the structure remains fully intact and operational throughout the entire testing process, minimising disruption to site activities.
Inspection Report & Documentation
Comprehensive inspection report with test locations, hardness readings, strength estimates, and engineering conclusions for use in structural assessment, compliance, or dispute resolution.
Our Process

The Hardness Test Process

A systematic approach by specialist engineers — from site survey and test planning, through calibrated on-site testing, to data analysis and full inspection report delivery.

1
Survey & Test Planning
Inspect the structure, identify test zones, and develop a testing plan with grid layout and target test points aligned with the inspection objective.
2
Surface Preparation
Lightly prepare the test surface by removing loose material, paint, or scale as required to ensure consistent and accurate hardness readings.
3
Hardness Testing & Measurement
Conduct systematic hardness tests at each designated point using calibrated instruments, recording all readings with precise location reference.
4
Analysis & Report Delivery
Analyse test data, correlate to strength values, and deliver a comprehensive inspection report with findings, hardness maps, and engineering conclusions.
Hardness Test Application
Applications

What Types of Work Is It Suited For?

Hardness Test is suited for any project requiring material strength data without structural damage — from existing building assessments to industrial steel inspections.

01
Existing Building Structural Assessment — Evaluate the hardness and estimated strength of concrete elements in existing buildings where original design records are unavailable, uncertain, or require verification.
02
Industrial Steel Structure Inspection — Test the hardness of structural steel, welds, and connections in industrial plants and factories to verify material grade and detect degradation or variation.
03
Construction Quality Control — Verify that freshly placed concrete or fabricated steel components meet specified hardness and strength requirements before acceptance and handover.
04
Pre-Repair & Strengthening Assessment — Assess the condition and strength of existing structural elements before planning repair, reinforcement, or CFRP structural strengthening works.
05
Material Investigation & Dispute Resolution — Provide objective hardness data for material disputes, forensic investigation, or insurance claims involving structural concrete or steel components.
