Crystalline waterproofing is a cutting-edge solution in the construction industry, and at Kryton International, we’ve pioneered its most advanced form. Our Krystol® technology is a specialized concrete admixture added directly to the concrete mix, where it reacts with moisture to form insoluble crystals. These crystals fill pores and microcracks, creating a permanent, self-sealing barrier against water intrusion from within the concrete itself.
At Kryton International, we are proud to be the pioneers of crystalline waterproofing technology with our Krystol® Internal Membrane (KIM). While this method offers long-term, self-sealing protection and has proven advantages over traditional waterproofing systems, we understand that no solution is one-size-fits-all. Here are a few considerations when using crystalline waterproofing:
1. Requires Proper Mixing and PlacementCrystalline admixtures must be thoroughly mixed into the concrete to ensure uniform distribution. Inconsistent mixing or poor placement practices can affect performance, which is why we offer detailed guidance and on-site support to ensure proper installation.
2. Performance Depends on Concrete QualityThe effectiveness of crystalline technology can be influenced by the quality of the concrete mix. Proper water-cement ratios, curing, and construction practices are essential. That said, Kryton works closely with project teams to ensure specifications and performance targets are met.
Despite these considerations, crystalline waterproofing remains one of the most reliable, cost-effective, and sustainable solutions for long-term concrete protection—especially when integrated early in the design and construction process. With over 50 years of experience and thousands of successful projects worldwide, Kryton ensures that potential limitations are addressed through expert support and quality assurance.
At Kryton International, we recommend using integral crystalline waterproofing during the construction of new concrete structures. By adding our Krystol® Internal Membrane (KIM) admixture directly to the concrete mix at the time of batching, you ensure permanent, full-depth waterproofing from the start.
This approach is ideal for new construction projects, such as foundations, basements, tunnels, water tanks, and other below-grade applications. Because the waterproofing becomes an integral part of the concrete, it provides lifelong protection against water ingress and hydrostatic pressure, reduces the need for surface-applied membranes, and minimizes long-term maintenance.
With Kryton’s proven crystalline technology, you can build with confidence—knowing your structure is protected from the inside out.
At Kryton International, our Krystol® crystalline waterproofing technology is designed to last the entire life of the concrete structure.
Because it is added directly into the concrete mix, Krystol Internal Membrane (KIM) becomes a permanent, integral part of the concrete matrix. Once in place, the proprietary Krystol chemicals remain dormant until activated by the presence of moisture. When activated, they form millions of insoluble crystals that block water pathways and continue to react whenever water reappears—self-sealing cracks and maintaining protection over time.
Unlike surface-applied systems that can degrade, delaminate, or require reapplication, Kryton’s crystalline waterproofing does not rely on adhesion or exposure and is not vulnerable to environmental wear and tear. It is engineered to perform for the full design life of the structure, even in the most challenging conditions.
With over 50 years of proven performance across thousands of projects worldwide, Kryton’s crystalline waterproofing solutions offer reliable, maintenance-reducing protection that stands the test of time.
At Kryton International, we understand that cost is a key consideration when selecting a waterproofing solution. While the initial cost of crystalline waterproofing—such as our Krystol® Internal Membrane (KIM) admixture—may be comparable or slightly higher than traditional surface-applied membranes, the long-term value and savings are significantly greater.
Because KIM is added directly to the concrete mix, it eliminates the need for external membranes, surface preparation, and the labor associated with membrane application. This can result in lower construction costs, faster installation, and reduced scheduling delays.
Even more importantly, KIM provides permanent waterproofing from within, reducing the need for future repairs, reapplication, or maintenance. Over the lifecycle of a structure, these savings can amount to a significant reduction in total cost of ownership.
