Xypex Admix C-1000 NF was specified to provide integral crystalline waterproofing. Laboratory tests confirmed minimal water penetration under pressure, validating its long-term performance. The result was a watertight underground structure that safeguarded the museum’s new facilities, ensuring resilience against hydrostatic pressure and extending the lifespan of the cultural landmark.
