How is Kryton Krystol Internal Membrane™ (KIM®) different?

Not all crystalline admixtures are the same

Image of How is Kryton Krystol Internal Membrane™ (KIM®) different?

Crystalline admixtures classified as Permeability Reducing Admixtures for Hydrostatic conditions (PRAH) are not the same. KIM consistently produces far better results. Understanding the differences ensures you can make an informed decision resulting in watertight structures for life.

Krystol Technology is CHEMICALLY UNIQUE

• KIM reacts with un-hydrated cement in concrete and continues to enable the growth of more crystals, ensuring long-term protection

• Long needle-shaped crystals grow deeper, fill smaller spaces, and resist more water pressure

• KIM is the original crystalline admixture and is chemically differently from competitors


• Highest level of permeability reduction and most dependable self-sealing performance

• Best dry shrinkage and restrained shrinkage crack reduction

• Only crystalline admixture proven to protect against corrosion of reinforced steel (proven by the 10-year Corrosion Study conducted by the University of Hawaii)


• Every construction detail is covered to create a watertight structure

• Entire waterproofing system comes from one manufacturer, ensuring ease of use and expertise

• Kryton is a one stop shop for all concrete waterproofing and durability needs

Kryton has the MOST EXPERIENCE

• Invented the world’s first crystalline admixture 15 years before competitors

• Offers the best warranty in category with many projects outlasting their original warranties

• Successful waterproofing of high-risk projects around the world

Make an informed choice. Only KIM can reliably waterproof concrete structures for life.
