TRON MIX-1000 is a concentrated waterproofing additive for concrete that forms crystals within concrete pores and cracks up to 1mm wide. It reacts with water to generate an insoluble crystal throughout the concrete that makes it highly resistant to water and other chemicals. TRON MIX-1000 can be added to concrete during mixing or used to repair existing structures and seal cracks. When the crystallization process is complete after curing, it provides permanent protection against water for structures.
