W. R. MEADOWS recently worked with Arcadis US, Inc. Design & Consultancy and Kokosing Construction Company to take on waterproofing the 219,000 ft.² Ottawa River Storage Tank in Toledo, Ohio. This massive underground tank was waterproofed using our HYDRALASTIC 836 fluid-applied membrane. HYDRALASTIC 836 is a cold-applied, solvent-free, single component waterproofing compound. It doesn’t shrink, has a low volatile organic compound (VOC) content, and also has very low odor. HYDRALASTIC 836 will not crack in extreme cold or slump due to softening at high temperatures. It is an excellent product choice for horizontal and vertical waterproofing applications, such as the…
