China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

Water conservancy and hydropower projects serve as crucial cornerstones of national infrastructure, bearing the significant responsibilities of flood control, power generation, water supply, and navigation. Transforming designs of dams, tunnels, and embankments into "steel-like barriers" on the ground relies on a millimeter or even sub-millimeter "geodetic measurement framework." Whoever can accurately calculate deformation, seepage pressure, and stress holds the key to locking down century-scale risks with precision.
We possess a professional testing team certified by the Ministry of Water Resources. We can provide differentiated testing and mix design validation services tailored to various dam types, tunnels, and embankments, helping your concrete demonstrate its unique performance label in "milestone projects."
