Non-Destructive Testing (NDT) is the standard method for assessing the integrity, local strength, and durability of civil engineering structures, existing buildings, or structures undergoing final inspection, without affecting their load-bearing capacity. The CTRMAT store offers a catalog of high-tech diagnostic instruments that strictly comply with European and international standards (NF EN 12504, NF EN 13791, ASTM):

• Rebound Hardness Testers: Mechanical hardness testers (Type N or L) and digital hardness testers with automatic recording to measure surface hardness and estimate local compressive strength in accordance with the NF EN 12504-2 standard.
• Reinforcement Detectors & Reinforcement Locators: Electromagnetic detection systems (e.g., the Elcometer range) used to map reinforcement, determine bar diameter, and measure concrete cover thickness in accordance with Eurocode 2 (NF EN 1992).
• Ultrasonic Testing: Devices for measuring sound propagation velocity (SPV) to detect internal voids, cracks, and segregation zones, and to assess the homogeneity of hardened concrete in accordance with standard NF EN 12504-4.
• Corrosion Assessment: Channels for measuring the corrosion potential of reinforcing bars to anticipate structural degradation in harsh environments.
