Salt damage investigation (salt analysis and corrosion survey for concrete and steel structures)

Visualize the salt content and accurately grasp the deterioration progress of structures that can be utilized in longevity planning.

Salt damage investigation is a survey conducted to evaluate whether concrete structures and steel materials are deteriorating due to the effects of salts contained in sea salt and de-icing agents. It is carried out on various structures, primarily focusing on social infrastructure such as bridges, buildings, port structures, and road structures. Our company conducts sample collection using the drill method or core method and quantitatively assesses the penetration of salts by analyzing the amount of chloride ions at different depths. Furthermore, by combining this with rebar detection using electromagnetic radar methods, we can correlate the positions of rebar with the amount of salt, allowing for a more detailed assessment of the progression of salt damage. Additionally, by conducting natural potential measurements and rebar exposure surveys, we can confirm the presence of rebar corrosion and the areas that require repair, providing valuable data for the consideration of maintenance and repair plans.
