Care for detail & precision through targeted actions We develop solutions for mankind and for the environment
Ladybugs, only 4 to 9 mm long, often almost go unnoticed and yet they are extremely important insects. They are known to bring good luck but they are also very useful creatures in the biological fight against pests such as aphids and mealybugs that are their most important sources of nourishment. Ladybugs protect plants and help them grow, thereby contributing in a significant way to keeping a balance in Nature.
By looking only at the surface, it is impossible to plan useful and qualified concrete renovation. Only an in-depth analysis and microscopic examination of the concrete of the tanks can allow us to provide our clients with detailed structural analyses before intervening with an optimized work plan.
Structural analysis in water treatment plants for designers and operators
On-site concrete analysis:
Measurement of the damage
Structural surveys
Exposure and scanner analysis of the reinforcement bars
Measurement of degree of carbonation
Tensile strength test
Coring
A wet coring drill on a support stand is used to extract samples then used for lab analysis.
Additional testing in specialised labs:
Compression test
Chloride and sulphates tests
Electron and optical microscope examination, if necessary, for detection of sulphate attacks or alkali-aggregate reactions
Testing for polycyclic aromatic hydrocarbons (PAHs) and/or asbestos
Tensile strength tests on samples of collected material
Additional carbonation measurements
Analysis of reinforcement bars
Mineralogical analysis of cores
- Phenolphthalein testing provides information about the depth of carbonation in the concrete structures.
- Salts and sulphates damage these structures. The laboratory discovers them using a physical/chemical process called ion exchange chromatography.
- Observation under an optical and electron microscope, when necessary, provides information about the mineral composition of the samples of material.
All of the information obtained in this way is summarised in a detailed report on the test results and, as a special service, explained on site by our expert planner. In this manner we create the premises for qualified renovation.
