Hydraton® is a low-permeability, thin capping material that resembles ordinary stone aggregates and can be constructed using manual labor or simple standard machinery, eliminating the need for mechanical compaction. Once hydrated, it attains a dense state. In comparison to other anti-seepage materials, Hydraton® boasts a lower anti-seepage coefficient, making it easier to ensure construction quality. Additionally, it saves construction time and costs, providing a more reliable anti-seepage solution.
