The most common building material
Durability can be dependent on workmanship and aggressive substances in the surrounding environment
Concrete Inspection
The world's industries and infrastructure are basically made up of concrete, which has fantastic properties, and this makes it the most common building material. But unfortunately, the circumstances are not always optimal, and depending on the work performed and different aggressive substances in the surrounding environment, the degradation process and persistence can vary greatly.
Through a systematic concrete inspection and status assessment, we can obtain the basis required to carry out the right maintenance work or repair at the right time, as well as maintain a safe construction with increased lifespan of the facility. Concrete inspection essentially consists of a combination of inspection and scanning (non-destructive testing, NDT).
DEKRA can help you with:
- Condition assessments of concrete structures, class 1 competence
- Life expectancy assessment and proposed measures
- Quality control of prefabricated concrete elements
- Inspection of newly produced concrete structures
- Preparation of technical description/frame description and consultation for concrete repairs
We also carry out concrete testing, including:
- Adhesion test and surface tensile strength (SS 137243 and EN 1542)
- Compressive strength (SS-EN 12390-3), crack strength (SS-EN 12390-6), and tensile strength (SS137231)
- Reinforcement control (cover layer, center distance, visual inspection) By scanning with a cover layer meter or GPR (Ground Penetrating Radar), we can locate reinforcement and various types of cast-in materials (plastic or steel drainage pipes, tension cables, etc.) in concrete structures. A non-destructive testing method that can present a result in 2D, 3D and AR formats.
- Concrete analyses: carbonation (SS 137242) and chloride content (Rapid Chloride Test, RCT method).
- Determination of rebound values with a Schmidt hammer (SS-EN 12504-2)
- Tensile testing of fasteners and reinforcing bars in concrete to determine tensile strength
- Scanning / non-destructive testing of concrete with ultrasound (UPE), GPR (Ground Penetrating Radar, cover layer meter and X-ray (RT)
Inspection of ski lift foundations
According to the housing association's statutory collection BFS 2016:2 H16, a more extensive inspection of the concrete foundations must be done every 5 years with regard to operation, corrosion and weather. Commonly occurring damages in the foundations are collisions, frost damage and cracking. In the event of damage to the covering concrete layer, the risk of reinforcement corrosion being initiated increases.
Concrete inspection
The lifespan of reinforced concrete structures can vary greatly depending on the design and various degrading factors. The concrete's ability to protect the reinforcement against corrosion is determined by measuring the pH value (for carbonation), the chloride content, thickness and quality of the concrete and the covering concrete layer. In addition to the sampling, a visual check is also made for any damage that may affect the foundation and the reinforcement.
