Roof decks, verandas, and balconies give multi-storey dwellings a vantage point from which to look out on a nice garden or stunning cityscape—or simply a place to chill and enjoy an evening under the stars with your family. But these are parts of the house are vulnerable to damage caused by constant movement and exposure to water and moisture. Enter Optimum Flex, a sturdy and flexible cement-based waterproofing solution from Jardine Distribution, Inc.’s (JDI). Optimum Flex seeps into, and permanently bonds with concrete to seal off pores and spaces where water may enter, while its optimum flexibility keeps concrete surfaces sealed against moisture despite frequent movements and tremors. The product allows the surface to breathe, prevents the buildup of vapor pressure, and does not trap moisture, which is the cause of leaks. Optimum Flex is manufactured by construction supplier, BASF.
