Leakage Stoppage and Grouting Material Testing

The leak stopping and grouting material industry provides indispensable repair materials for infrastructure construction, primarily used for treating concrete cracks and pipeline leakage issues. The Yangtze River Delta and Pearl River Delta regions, due to high building density and strong demand for old facility renovation, have become core markets.

Inspection and testing serve as the technical engine for the regularization of building repair. Facing the chaotic situation in the building repair market, our testing team is shifting from “post-incident testing” to “full-cycle quality control”, strengthening client protection barriers.
