A US patent has recently been granted to a new test to prove and measure the self-sealing qualities of concrete mixes. This approval confirms the robustness of the test, therefore establishing a uniform way in which this property can be quantified within any mix of concrete, including those which incorporate speciality admixtures.
The patent was granted for ‘A Method, Apparatus and System for Testing the Self-Sealing Capabilities of a Concrete Sample’ to Kryton International Inc. Kevin Yuers, Vice President at Kryton, devised the test in conjunction with Rishi Gupta, assistant professor of civil engineering at the University of Victoria, British Columbia, Canada.
Kryton produces a range of concrete waterproofing products which incorporate their unique patented Krystol technology. Krystol reacts with moisture causing long, narrow crystals to form, filling the pores, capillaries and hairline cracks of the concrete mass. The Krystol remains permanently within the concrete and continues to react with any present moist
