Concrete Crack Mapping
Atlas Engineering and Technology Group provides comprehensive concrete crack mapping services across Sydney and surrounding regions. Our experienced technicians systematically document, classify, and assess crack patterns in concrete structures to help you understand the condition of your assets and plan effective remediation strategies.
What Is Concrete Crack Mapping?
Concrete crack mapping is a detailed visual inspection and documentation process used to record the location, type, width, length, and orientation of cracks across a concrete surface. The resulting crack map serves as a diagnostic tool, helping engineers identify the underlying causes of deterioration and assess the structural significance of observed defects.
Why Is Crack Mapping Important?
Cracks in concrete can indicate a range of issues, from minor surface shrinkage through to significant structural distress. Without a systematic survey, it can be difficult to distinguish cosmetic defects from those that require urgent attention. Crack mapping provides a clear, repeatable record that supports informed decision-making for maintenance, repair, and asset management programs.
Common Causes of Concrete Cracking
- Plastic shrinkage and drying shrinkage
- Thermal expansion and contraction
- Structural overloading or settlement
- Reinforcement corrosion and concrete carbonation
- Alkali-silica reaction
- Poor construction practices or inadequate curing
Our Crack Mapping Process
- Initial site assessment and scope definition
- Establishment of a grid or reference system on the concrete surface
- Visual inspection and identification of all visible cracks
- Classification of cracks by type, width, depth, and orientation
- Measurement using calibrated crack width gauges and rulers
- Photographic documentation of key defects
- Preparation of a scaled crack map drawing
- Detailed reporting with findings, interpretation, and recommendations
Crack Classification
We classify cracks according to recognised industry standards, considering the following characteristics:
| Characteristic | Details |
| Width | Hairline (less than 0.1 mm) through to wide (greater than 1.0 mm) |
| Depth | Surface, partial depth, or full depth |
| Pattern | Linear, map/pattern, transverse, or longitudinal |
| Activity | Live (active movement) or dormant (stable) |
Applications
- Condition assessments for commercial and residential buildings
- Bridge and infrastructure inspections
- Pre-purchase and dilapidation surveys
- Monitoring of crack progression over time
- Quality assurance during and after construction
- Input for structural engineering assessments and repair design
Relevant Standards
Our crack mapping services are carried out in accordance with Australian Standards and industry guidelines, including AS 3600 (Concrete Structures) and AS 3799 (Liquid Membrane-Forming Curing Compounds for Concrete), as well as internationally recognised references where applicable.
