SS-CAS Expansive Admixture is designed to compensate concrete shrinkage and improve volumetric stability. It is suitable for waterproof concrete and large-volume structures, helping reduce cracking risk and enhance structural integrity. Compared with traditional waterproofing materials, it offers economical performance and simplifies construction, especially for complex structural areas where membrane waterproofing is difficult.
