Surface Applied Waterproofing    Kryton Krystol T1 T2 VideoNegative and Positive Side Waterproofing

Krystol T1 & T2 system is a crystalline based surface applied waterproofing treatment for concrete and cementitious structures that is used to protect against the ingress and leakage of water. It is a dry powder, that when mixed with water becomes a coating that is applied to the interior or exterior sides of a concrete structure. A surface applied waterproofing treatment for new and existing pre-cast or placed concrete and masonry block. Krystol T1 and T2 grows deeper into the concrete struture, and outperform direct competitors for waterproofing properties in independent side-by-side tests.

How It Works – Crystalline Waterproofing

Negative Side Surface Applied Waterproofing & Positive Side Surface Applied Waterproofing

Krystol T1 & T2 is an “in-depth” concrete treatment that is applied as a slurry or spray to the surface of existing concrete structures. In the presence of water, the special chemicals will react with the concrete to grow millions of long, needle-shaped crystals deep into the concrete mass. These surface applied waterproofing crystals permanently block and prevent the passage of water through capillary pores, micro-cracks and joints. The concrete itself becomes the waterproof layer and the surface treatment is not required to remain intact for the system to be effective. As a result, the Krystol T1 & T2 System is extremely durable and will last the lifetime of the concrete. The system is comprised of two products Krystol T1 and Krystol T2.

Without adequate waterproofing, both the structural integrity and profits of a structure are at risk. Kryton takes the risk out of concrete waterproofing. We develop, manufacture and market products that waterproof, repair and protect concrete structures. Only we do it permanently. Our technology transforms concrete into a waterproof barrier. Short term, you’ll shave weeks off construction schedules, cut waterproofing costs up to 40% and maximize your building footprint. Long term, you’ll avoid leaks, discoloration, and costly callbacks. Kryton is the inventor of the crystalline waterproofing admixture and has been waterproofing concrete since 1973. The impact of our technology is evident in the world’s most challenging construction projects. From immense hydrostatic pressure in the deepest underground pits, to the rooftops of the highest skyscrapers; we’ve provided solutions for them all, from Argentina to Australia, China to Croatia, the UAE to the USA. Today, Kryton has offices around the globe, over fifty distributors in forty countries and operates the largest concrete permeability testing laboratory in North America. As Kryton was built on the spirit of science and research, it is still at the core of our business today.

The New World Trade Center Transportation Hub is just one of five new buildings which will make up the improved vision of downtown New York. Sustainable commercial space, convenient transportation, and a destination cultural center are all attributes which have been balanced gracefully within the new rebuild of the World Trade Center to symbolize the resilience and renaissance of not only New York – but of the entire country. This vision also unites an unprecedented merging of architects, artists, and urban developers, including Santiago Calatrava, David Childs, Norman Foster, Frank Gehry, Daniel Libeskind, Fumihiko Maki, and Richard Rogers. The singular goal is a grand new urban center for 21st century New York, and promises to become the most recognizable site in New York. Even esteemed projects such as these buildings are not without their hurdles. Located in lower Manhattan, two blocks from the Hudson River, the buildings are in a flood zone. The 9A Underpass and North Extension commuter passages, were experiencing what many below-grade concrete structures face – water infiltration. Leaking concrete cracks, damp areas and water penetration through joints were becoming increasingly hazardous to this area used by hundreds of thousands of commuters every day, due to its location adjacent to the new Freedom Tower. Many products were applied to attempt to mitigate the water damage. The problems were found to have been caused by failed external sheet membranes, and due to blind side application, they were impossible to access in or to replace or repair. Injection systems were attempted to address the leaking cracks and persistent damp areas, with results proving only temporary, while costing thousands of dollars in additional labour.


Greg Maugeri and Billy Della Sorte of Dry Concrete personally assessed the problems the passages were facing. Through countless early morning site visits, the Dry Concrete team performed trials and provided support and technical expertise. As long time Kryton distributors, Dry Concrete has a strong familiarity with the Krystol Cracks Repair System, and through their experience, could confidently recommend it as a permanent solution to the leakage problems. After demonstrating the performance of the products on a wall of one of the passageways, the project’s decision makers agreed with Dry Concrete’s recommendation. The Krystol Crack Repair System was the only concrete repair solution that was able to stop the leaks and return the problem areas to a dry state. Approved by both the Downtown Design Partnership (DDP), and the Port Authority of New York and New Jersey (PATHNYNJ), the Krystol Crack Repair System went to work, effectively sealing the leaking cracks, while providing permanent protection against high ground water pressure. The proprietary chemicals used in the Krystol products will only get more effective at preventing water penetration over time. These chemicals lie dormant throughout the life of the concrete structure, reacting with any present moisture to create hair like, permanent crystals which stop any water from entering the structure.  Gamka Sales Co Inc is a full service distributor with over 30 years of experience in concrete and concrete related problems and solutions.
