Hydrostop Restore & Protect System from Kryton International is a three-step restoration and protection system for above-grade concrete structures that extends the useful life of aging concrete infrastructure, improves appearance, and offers a more sustainable alternative to total replacement. Step one is the application of a nonshrink waterproof grout to repair cracks and defects. Once the substrate is repaired, the entire surface is coated with a polymerized, cementitious slurry that provides a barrier against water and chemical intrusion. The last step creates a long-lasting water-repellent effect with a blended silane-siloxane sealer. kryton.com
