WHY CHOOSE US
Undertaking any new construction and renovation projects comes with the potential issue of needing to cut or core concrete slabs. With this comes the risk of striking electrical and communications conduits, post tension cables and rebar which can be hidden in the concrete wall or floor. Mistakes such as these can add strain to your financial budget and time schedule; not to mention, creating a safety hazard for your construction team.
Concrete scanning is a cost-effective, non-destructive method of obtaining information on items within concrete structures or below the ground. We are able to safely locate steel reinforcement, post tension cables and anomalies. It allows construction industry professionals to make informed decisions prior to concrete cutting and core drilling.
At Conscan, our highly skilled and experienced technicians respond quickly and efficiently to any request for our concrete scanning service. The outcome of our professional services is accurate and prompt scanning that mitigates the potential risks and keeps your employees safe.
OUR SERVICES
Concrete scanning is crucial for analysing the contents of concrete structures. This includes the depth of the concrete itself as well as information about the rebar such as its spacing and position within the concrete.
Our non-invasive Ground Penetrating Radar (GPR) technology can find steel reinforcement, post-tension cables, live power, conduit and many other items. Concrete analysis thus gives engineers the information they need to make decisions regarding the structure. This allows accuracy to cut into concrete surfaces with confidence, knowing that any hidden items have been identified.
- Scanning for drilling and cutting concrete
- Discovering any voids in the concrete walls, ceilings, subgrade, or slab
- Pinpointing the location of objects such as rebar and post-tension cables
- Establishing the position of embedded power cables within the concrete
- Slab mapping and depth sizing
- Identifying structural steel elements
- Inspection purpose concrete scanning
Concrete buildings are vulnerable to corrosion due their reliance on steel bars or mesh for reinforcement. Exposure to air and water causes the steel to expand and corrode. As the damage to the internal steel framework worsens, the surrounding concrete also starts to fail. This is known as concrete spalling or concrete cancer.
Concrete is porous, so it absorbs the carbonic acid created during the corrosion process. This accelerates the concrete spalling and eventually leads to expensive property damage. Common signs of spalling include cracking, flaking, crumbling, rust stains or bubbling on the concrete or cement render and leaks in the roof and walls.
- Detection of corrosion in reinforcement
- Measurement of rebar corrosion rate
- Evaluation of corrosion potential of rebar
- Measurement of in-situ electrical resistivity
- Assessment of concrete durability
With our professional concrete scanning equipment, we can accurately measure the thickness of a concrete slab, map size reinforcement and locate appropriate sites for core samples to be taken. We offer chemical analysis of core samples, such as chloride and sulphate intrusion profiles, as well as carbonation. Testing involves placing a steadily increasing load down the length of the core sample until the sample fractures and breaks. The load at which the concrete collapses will indicate its compressive strength, and from this can be calculated an array of useful information. Crush testing of core samples can be provided and analysed to measure flex and deformation in our National Association of Testing Authorities Australia (NATA) accredited facility.
Our NATA accredited laboratory will then provide a report of the outcome of the crush test which Conscan will forward on to the customer. Onsite hardness testing can also be accommodated using our advanced NDT testing equipment and following relevant industry standards.
- Strength and density determination
- Depth of carbonation of concrete
- Chemical analysis
- Water/gas permeability
Non-Destructive Testing (NDT) is an important method for assessing the condition and integrity of existing reinforced structures. After visual inspection, NDT can identify the location of the issue, the rate at which damage has occurred and the severity so that appropriate action may be taken to prevent further deterioration.
We use Ultrasonic Transducers to create highly intuitive images of the internal structure of the concrete. This ultrasonic technique is highly sensitive to air voids, cracks and honeycombing with the concrete while still providing images of metallic items in most cases.
- Location of defects such as voiding or delamination of concrete
- Thickness measurements of concrete elements
- Detection of objects in conventional or steel fibre reinforced concrete
- Evaluate the grouting of post tension tendon ducts
Conscan provide our clients with reporting as an added service. Our reports contain information on the areas scanned, advice on slab thickness, reinforcing patterns and any other anomalies in the test area. These reports can be distributed to other trades and professionals involved in the project.
