KIM is used in place of externally applied surface membranes to protect concrete structures against moisture transmission, chemical attack and corrosion of reinforcing steel.When combined with fresh concrete, Kryton’s unique and proven Krystol® technology reacts with un-hydrated cement particles to form millions of needle-like crystals. Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants. Later, if cracks form due to settling or shrinkage, incoming water triggers the crystallization process and additional crystals form, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected. In addition to filling the pores and capillaries of the concrete matrix with crystals, KIM enhances the natural hydration process by intensifying and prolonging the hydration of the cementing materials. This reduces the size and number of capillary pores within the concrete matrix, making it dramatically less porous, and improving strength and durability characteristics.FEATURES• KIM is a permeability reducing admixture for hydrostatic conditions (PRAH)• Replaces unreliable exterior membranes, liners and coatings• Easily added directly to ready-mix truck or at batch plant• Self-seals hairline cracks up to 0.5 mm (0.02 in.)• Reactivates in the presence of moisture• Effective against hydrostatic pressure up to 140 m (460 ft.) of head pressure• Waterproofs from any direction (i.e. positive or negative side)• Impervious to physical damage and deterioration• Safe for contact with potable water, certified by NSF to NSF/ANSI Standard 61 Drinking Water System Components – Health Effects• Reduces concrete shrinkage and cracking• Provides excellent resistance to waterborne chemicals such as sulfates, chlorides, and acids• Compatible with self-compacting concrete (SCC)KEY BENEFITS• Permanently waterproofs concrete• Increases reliability and quality control• Lowers the cost of waterproofing by up to 40%• Shaves weeks off the construction schedule• Reduces the cost of maintenance and repairs• Increases revenues with a larger building footprintConcrete Waterproofing Admixture 1of 7Kryton, Krystol and KIM are trademarks of Kryton International Inc. ©20111645 East Kent Avenue, Vancouver BC, Canada V5P 2S8 | tel 1.604.324.8280 | fax 1.604.324.8899 | toll free 1.800.267.8280 | web kryton.comKryton, Krystol and KIM are trademarks of Kryton International Inc. ©2011 V. 2013-03Kryton International Inc.Kryton International Inc.4 1645 East Kent Avenue, Vancouver BC, Canada V5P 2S8 | tel 1.604.324.8280 | fax 1.604.324.8899 | toll free 1.800.267.8280 | web kryton.comRECOMMENDED USESUse KIM to provide permanent protection for all concrete that will be subject to water pressure, such as:• Below grade parking structures, basements, elevator pits and foundations of high-rise towers• Recreational facilities such as aquatic centers, aquariums, zoos, water parks and marinas• Architectural water features such as fountains and waterfalls• Water containment reservoirs, water treatment tanks, sewage and manholes• Traffic tunnels, below grade pipelines and subway tunnels• Bridges, dams and highway infrastructure• Concrete homes including basements, foundations, swimming pools, decks, bathrooms, garages and exteriors• Properly designed roof tops and plaza decksPHYSICAL PROPERTIES Appearance Light gray powder Particle size (µ) 40-150Bulk density g/cm3 (lb./cu. ft) ~1.4 (88)Specific gravity ~2.8PLASTIC PROPERTIESThe KIM admixture has been further optimized to meet the requirements of projects in various climate conditions. The three types of KIM include:• KIM-HS: This version of KIM is used for most common applications. KIM-HS is compatible with common admixtures, such as plasticizers, accelerators, retarders and air-entrainers.• KIM-AE: This version of KIM is specially designed for concrete requiring air-entrainment to resist freezing and thawing cycles. KIM-AE will increase air content by 3-5%. Adjust or remove any air-entraining admixtures accordingly.• KIM-ES: This version of KIM is specially designed for use in hot climates and mass concrete. KIM-ES will prolong the slump retention of the concrete and delay the initial setting time. Adjust or remove set retarding admixtures accordingly.All versions will typically delay the setting times of the concrete. Consult with a Kryton Technical Services Representative for the most appropriate KIM admixture for your project.

The specimens were then subjected to hydrostatic pressure of 500 KPa (72.5 psi) for a period of 72 hours. This pressure is equal to 51 m (167 ft.) of water head pressure. Maximum penetration of less than 3 mm (0.125 in.). The specimens exhibited no leakage or dampness. Al-Fattaim Tarmac Laboratories, 2002 Concrete specimens containing KIM (@ 2% cmts) and a 0.40 water to cement ratio were cast and aged for 28 days. The specimens were then subjected to hydrostatic pressure of 500 KPa (72.5 psi) for a period of 72 hours. This pressure is equal to 51 m (167 ft.) of water head pressure. KIM performed 10x better than the control, allowing only 3.7 mm (0.146 inches) of water to penetrate the sample. Kuwait University, Civil Engineering Testing Center, 2004ICBO/ICC Water Percolation Test (Modified ASTM D4068 annex A2)Concrete specimens containing KIM (@ 2% cmts) were cast and aged for 28 days. The specimens were then subjected to hydrostatic pressure imposed by water columns 1.22 m (48 in.) in height. The specimens met the acceptance criteria, which is no water passing through the specimens and maximum 12.5 mm (0.5 in.) of water drop in the columns after 48 hours. Inspection Concepts California, 1993 CRD C48 - 92 – USACE Standard Test Method for Water Permeability of ConcreteSix concrete specimens containing KIM (@ 2% cmts) were cast and aged for 28 days. The specimens were then subjected on one side to hydrostatic pressure of 1.38 MPa (200 psi) for a period of 14 days. This pressure is equal to 140 m (460 ft.) of water head pressure. There was no leakage through any of the specimens.UBC/Kryton, 2003A similar test was conducted by AGRA Earth and Environmental in 1995, which compared reference concrete mixes of high strength concrete (50-60 MPa) with and without the addition of KIM. Results of permeability testing show that even for these mixes, KIM achieved 57% and 75% reductions in permeability over the reference mixes.

The RCP test is widely accepted as a test for concrete permeability. Lower values reveal less chloride penetration and thus lower permeability. Concrete specimens containing KIM (@ 2% cmts) were tested on separate occasions by The Port Authority of New York & New Jersey and by AMEC Earth and Environmental. Chloride permeability was shown to be reduced by 45% in both tests.The Port Authority of New York & New Jersey, 1998AMEC Earth and Environmental, 2000SULFATE RESISTANCE Krystol treated concrete specimens exhibited excellent sulfate resistance when tested in accordance with US Bureau of Reclamation guidelines. Specimens were alternately soaked in sodium sulfate solution and oven dried. The specimens were tested for strength loss and weight change. The Krystol treated specimens dramatically outperformed both the control specimens and the competitor’s specimens. R. M. Hardy and Associates, 1976The lower permeability of KIM-HS concrete will reduce the ingress of sulfates.British Board of Agreement (BBA) Agrément certificate No 05/4217, 2005COMPRESSIVE STRENGTH ASTM C494: Type D, CAN/CSA A266.2-M: Type WR – Chemical Admixtures for ConcreteConcrete specimens containing KIM (@ 2% cmts) displayed increases in compressive strength of 12% to 19% at ages 3, 7, 28 and 56 days compared to control specimens of equal slump and air.
