Cracks in concrete buildings are common, but not every crack has the same cause or significance. When a crack appears on a wall, column, beam, floor slab or other concrete element, simply taking a photograph may not provide enough information for an engineering assessment. A structural engineer, building inspector or testing company may need to know: How wide is the crack? How deep is the crack? Is the crack changing over time? This is where proper concrete crack inspection equipment becomes useful. MTM Precision supplies concrete and structural NDT equipment in Malaysia, including Langry crack width and depth testing instruments for professional building and civil engineering inspection. Why Should Concrete Cracks Be Measured? Descriptions such as: “small crack” “hairline crack” “large crack” “serious crack” are subjective. Actual measurements provide more useful information. For example, instead of reporting: “There is a visible crack on the concrete wall.” an inspector can record the measured crack width at a specific location and date. Measurements can then form part of the inspection record for review by the responsible engineer. Crack Width vs Crack Depth These are two different measurements. Crack Width Crack width describes the opening visible at or near the concrete surface. It can be useful for: Building condition surveys Concrete repair assessment Crack monitoring QA/QC documentation Structural investigation Crack Depth Crack depth attempts to determine how far the crack extends into the concrete. This can provide additional information when investigating the condition of a concrete element. A visible surface crack does not by itself reveal its full depth. Therefore, projects requiring more detailed investigation may need both crack width and crack depth measurement. Langry CWD800 Crack Width & Depth Tester For customers who require both measurements, the Langry CWD800 Crack Width & Depth Tester is particularly relevant. Instead of purchasing equipment only for visual crack-width measurement, the CWD800 provides a solution aimed at investigating both crack width and depth. This makes it suitable for professional applications such as: Building inspection Structural condition assessment Concrete investigation Bridge inspection Tunnel inspection Infrastructure maintenance Concrete repair projects Engineering laboratories For consultants and testing companies performing different types of concrete investigation, this combination can be particularly useful. Where Should Concrete Cracks Be Investigated? Cracks may appear in many parts of a concrete structure. Typical locations include: Concrete walls Floor slabs Beams Columns Basement structures Car parks Retaining walls Bridges Tunnels Concrete tanks Industrial structures The presence of a crack does not automatically mean a structure is unsafe. Likewise, appearance alone should not be used to determine whether a crack is structurally significant. The cause and significance should be evaluated by an appropriately qualified professional where required. Building Crack Inspection A building owner may first notice a crack visually. The next step should not automatically be to cover it with paint or repair material without understanding the situation. Depending on the project, an investigation may include: Visual Inspection ↓ Record Crack Location ↓ Measure Crack Width ↓ Investigate Crack Depth if Required ↓ Monitor Changes ↓ Engineer Assessment ↓ Repair / Further Investigation if Required Instrumentation helps turn a visual observation into measurable data. Crack Monitoring Over Time One measurement provides information about the crack at a particular moment. For some investigations, the more important question is: Is the crack getting wider? Measurements taken at defined locations over time can help create a record of crack behaviour. For example: Inspection 1 → Record measurement Inspection 2 → Repeat at the same location Inspection 3 → Compare results Consistent measurement procedures are important when comparing data collected at different times. Concrete Cracks in Old Buildings Older buildings are an important application for structural inspection equipment. Cracks may be investigated during: Renovation Building purchase assessment Structural alteration Change of building use Maintenance Concrete repair Waterproofing work Building condition assessment However, crack measurement alone may not provide enough information about the overall concrete structure. Additional NDT methods may be appropriate. Combine Crack Testing With Rebar Scanning If cracking occurs in reinforced concrete, engineers may also want information about the reinforcement. A Langry RS Series Rebar Scanner can help investigate: Rebar location Concrete cover Reinforcement arrangement This creates a more useful inspection combination: Crack Measurement + Rebar Scanning Rather than only seeing the crack, the investigation can also obtain information about reinforcement beneath the concrete surface. Combine Crack Testing With Concrete Strength Assessment Concrete condition may also need to be investigated. A Langry RH225A or RH225B Concrete Test Hammer can provide rebound measurements for concrete assessment. This creates another inspection combination: Crack Tester + Concrete Test Hammer For more comprehensive investigations: Crack Tester + Rebar Scanner + Concrete Test Hammer can provide three different types of field information. Add Ultrasonic Concrete Testing For advanced concrete NDT applications, ultrasonic testing can provide another layer of investigation. A Langry ultrasonic pulse velocity tester may be considered where ultrasonic assessment is part of the required test programme. The equipment package can therefore develop from: Visual Crack Inspection ↓ Crack Width / Depth Measurement ↓ Rebar Scanning ↓ Rebound Hammer Testing ↓ Ultrasonic Concrete Testing The appropriate combination depends on the engineering objective. Concrete Crack Inspection After Water Leakage Water leakage and cracking are often encountered together during building maintenance investigations. A waterproofing contractor may see a crack and need to determine its location and dimensions before planning repair work. This creates demand for crack inspection equipment outside traditional NDT laboratories. Potential users include: Waterproofing contractors Concrete repair contractors Building maintenance companies Facility management teams After repair, additional testing such as pull-off adhesion testing may also be relevant depending on the repair system and project specification. Concrete Crack Inspection After Renovation Cracks discovered during renovation may require further investigation before alteration works continue. This is particularly relevant when cracks occur near: Beams Columns Structural walls Floor slabs Existing openings Renovation contractors should not determine structural significance based solely on visual appearance. Where structural concerns exist, an appropriate engineer should assess the condition. Who Needs a Concrete Crack Tester in Malaysia? Potential customers include: Structural engineers Civil engineers Consulting engineers NDT companies Building inspection companies Testing laboratories Main contractors Concrete repair contractors Waterproofing contractors Building maintenance companies Facility management companies Bridge inspection teams Infrastructure contractors Universities and research institutions Many of these customers may search for the problem, rather than a particular instrument model. Typical searches may include: How to measure concrete crack width How to measure concrete crack depth Building crack inspection equipment Malaysia Concrete crack detector Malaysia Structural crack testing equipment Concrete crack monitoring Malaysia This is why MTM Precision provides equipment according to the customer's inspection requirement. What Other Equipment May Be Needed? A crack may only be one symptom observed during a structural investigation. Depending on the project, customers may also need: Inspection RequirementEquipmentConcrete strength indicationConcrete Test HammerRebar locationRebar ScannerConcrete coverRebar ScannerCrack widthCrack Width TesterCrack depthCrack Depth TesterSlab thicknessFloor Slab Thickness TesterAnchor verificationPull-Out TesterRepair adhesionPull-Off TesterUltrasonic concrete investigationUPV Tester MTM Precision can assist customers in building a suitable Concrete & Structural NDT equipment package rather than purchasing instruments individually without considering the complete inspection requirement.
