Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
KIM lowers the permeability of concrete, and is used in place of surface applied waterproofing membranes. By stopping the transmission of water through concrete, KIM adds durability and longevity to concrete by protecting it against chemical attack and corrosion of reinforcing steel.
KIM contains Krystol technology. When added to concrete, Krystol chemically reacts with water and un-hydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing protection.
KIM is recommended for all concrete that will be subject to water pressure and can be used in precast, cast-in-place and shotcrete applications.

KIM is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
Structural shotcrete is becoming a preferred concreting method in foundation construction, building tanks, parking garages and many other structures because it’s up to 50% faster than conventional cast in place.
Use the right products to protect and increase the lifespan of infrastructure in harsh marine environments.
The most effective concrete waterproofing system in the world. Kryton’s Smart Concrete® solutions contain proprietary technologies that allow concrete to respond to its environment to protect itself against water penetration and corrosion, or erosion and abrasion.
Krystol Internal Membrane™ (KIM®) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
Construct watertight tunnels that last. Tunnels can be subjected to heavy traffic and vibration, temperature changes, corrosion damage and freeze thaw cycles which affect the tunnel’s durability.
Krystol crystalline admixture and other technology is based on principles that are very similar to the processes that occur during the hydration and hardening of concrete. ...
When concrete producers want to modify the properties of concrete, supplemental cementing materials (SCM’S) can be used to achieve the intended goal. ...
It’s becoming clear to many leaders involved in the construction industry that waterproofing concrete from the inside out is the best choice. ...
Traditional waterproofing methods encourage the use of positive-side waterproofing during construction. However, this requires access to the outside wall of the concrete structure. ...
It’s the intelligent, self-sealing water-protection system that transforms concrete into a powerful water-resistant barrier through crystalline admixtures or surface applied treatments. ...
