CN2000 Test Results

National Research Council and Queens University Tests

In addition to the multiple manufacturer tests conducted, Kelso Coatings has commissioned several significant tests with important labs in Canada. Tested by PhDs and Engineers at Queens University and the National Research Council of Canada, Kelso Coatings confirmed that the CN2000® coating can stand up to extreme hydrostatic pressure and significant corrosion resistance. Originating in China, CN2000® has been applied to multiple airports and infrastructure landmarks in Canada and China in the last decade. In Canada, we have six years of experience waterproofing structures where customers have seen astounding results.

Effect of CN2000B coating on chloride ion penetration in concrete - laboratory evaluation


The purpose of this project was to assess the effectiveness of CN2000B® waterproof coating on reducing chloride ion penetration into concrete and evaluate the coating durability. The coating was applied on the surface of concrete specimens according to the manufacturer's requirements and procedures.

After long-term freezing-and-thawing cycles, the electrical charges passed through all specimens were stable, indicating no deterioration of the coating. The visual inspection of these coatings confirmed that no cracks, spalling or chips were observed on the coatings. From this test, it is observed that the CN2000B® coating might be able to resist the severe winter freezing-and-thawing conditions.

Waterproofing of Concrete for Reducing Permeability of Concrete Infrastructure, using CN2000 Coating Product


Permeability of concrete, combined with various levels of cracking, including micro- and macrocracking, directly contribute to migration of fluids, including water through the structure, which in turn negatively affects durability. The two fundamental damaging mechanisms associated with water intrusion into concrete are corrosion of steel reinforcements if water carries dissolved chlorides from salts or other chemicals, and freeze-thaw under cyclic temperatures which increases cracking further due to the expansion of frozen water. Revolutionary Concrete Solutions Inc (RCS) uses a new product (CN2000) that seals the concrete surface through a high efficient elastic waterproof coating that is applied to the concrete surface. The coating material combines polymeric and cementitious characteristics. As such, in addition to coating the outer surface, it also has the ability to continue the hydration process in presence of moisture for extended time and penetrates beyond the concrete surface and seals the micro pores and capillary tracts of the concrete. Thus, the performance of the coating is expected to improve with time.

RCS has approached Queen’s researchers to establish a framework of thorough understanding of the mechanism by which the product actually works with concrete, and specifically to carry out a rigorous permeability testing of concrete coated with the product under conditions that simulate real life field applications. The research team at Queen’s University has the necessary expertise in the field to understand and explain the underlying scientific mechanisms behind the concrete sealing phenomenon of the new CN2000 coating, through a rigorous testing program. This report summarizes the work completed in the first phase of collaboration with RCS that was funded by the NSERC ENGAGE program to evaluate the reduction in permeability of concrete coated with CN2000. The test matrix was based on the application purposes of the CN2000 product and included 65 specimens. A total of 11 specimens were tested out of the 65 specimens representing the total number of tests. This represents five parameters out of total of nine parameters planned for the study.

It was found that the use of CN2000 product helps delaying the water leakage by almost 22 times under an average water pressure of 3.3 MPa and an average triaxial pressure of 5.0 MPa. It should be noted that the 3.3 MPa water pressure is quite significant and likely higher than the pressures common (non-specialized) concrete structures are typically exposed to. The use of the CN2000 product helped reducing the water migration through the concrete samples significantly.

Continuing testing the rest of test parameters beyond the duration of the NSERC ENGAGE program is necessary, especially for how permeability coefficients change as the water pressure and triaxial pressure changes.
