Concrete scanning is the act of reading what sits under a concrete surface via the use of non-intrusive technology.

This is done in order to identify whether there are elements sitting under a concrete’s surface or to obtain an understanding of a known element’s condition.

Concrete scanning is further able to identify whether anomalies such as voids or cracks exist under a concrete surface.

All of these scenarios are then interpret by our leading industry specialists who are readily available to help you with any endeavours you have in mind.

Concrete scanning is the conducted via the use of non-intrusive technology such as ground penetrating radar (GPR), a cover meter, ferroscan instrument, ultrasonic scanning equipment and the like.

This technological equipment is able to non-intrusively penetrate your concrete structure and understand what is going on beyond its surface.

Once this has been conducted, industry specialists are then able to interpret the findings and report back to you on the condition of your concrete.

Additionally, recommendations regarding how to repair any poor condition found within the concrete are likewise provided.

Concrete scanning is able to detect a large range of different elements, depending on the technology which is being used. Overall, however, and in general, it is able to identify elements such as pipes, metals, asphalt, cables, masonry and such. Concrete scanning is further able to record and understand changes in material properties and any voids and cracks existing below the surface of a concrete structure. This scanning method holds the ability to be conducted on a large variety of mediums beyond concrete such as rock, clay, sand, coil, ice, water, pavements and more. In addition, this scanning method is likewise able to identify and communicate the condition in which a sub ground element or object is found to be in (e.g. corrosion, etc.)

Concrete scanning is an extremely effective scanning method.

Concrete scanning experts consider ground penetration radar (GPR) technology to be the best technique for scanning concrete.

GPR penetrates deeper than other methods.

The technology Structural Repairs uses has a better resolution than Ferroscan and the Cover Meter. The detection is not limited to metallic objects like these two methods.

GPR is further able to detect changes in a concrete’s subsurface and can detect most materials including plastic, wood and voids.

Overall, however, GPR technology is known for its precise, effective and very successful outcomes as it is able to provide specialists and clients with full and comprehensive reports regarding the condition of a concrete structure.

Concrete scanning is often required due to a large range of different reasons. For example, it is often necessary to understand the condition of any reinforcing bars lying at the core of the concrete structure as a means to understand its structural stability and strength. Concrete scanning is a common practice in renovation projects that involve cutting or coring of concrete slabs because it is crucial to understand if there is anything beneath the surface of these slabs. Failing to identify what is beneath the surface of a concrete slab could be potentially dangerous. It could result in injuring workers and causing accidents. Furthermore, cutting into elements such as electrical cables is not only extremely dangerous and potentially deadly, but is likewise very costly as this would disrupt the electrical supply, cause technical damage and delay the project. Concrete scanning can also be used as a preventative measure to maintenance the healthy of your structure through proactive, rather than reaction, action.
One of the main advantages of using concrete within the structure of a building is the resistance it has against fire. Fires typically visually affect most building materials, making it easy to identify them as unfit for use and later replace them. Concrete on the other hand changes very little in respect of the shape and size making it much more difficult to assess for damage. Concrete loses strength when heated above 300°C. Currently, people enter potentially dangerous and unstable parts of the building to assess damage and propose suitable repair methods or decide if demolition is necessary. Therefore, there is a greater need for new assessment technology. Our GPR and Ultrasound technology is the best non intrusive solution to survey and identify any voids and delamination. industry specialists are then able to interpret the findings and report back to you on the condition of your concrete.
