Krystol Waterproofing Admixtures impart durability in concrete structures
Recent University of Ottawa research demonstrates the effectiveness of Kryton International’s hydrophilic waterproofing products in critical conditions, including those where concrete mix designs must account for the risk of alkali-silica reaction (ASR) due to the presence of highly reactive aggregates. The four-year study investigates the performance of mix designs containing reactive aggregates, designated TX and SPH, along with Kryton’s products…
