W. R. MEADOWS Waterproofs the Ottawa River Storage Tank
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…
Protect your structure from harmful Radon
Radon is a naturally occurring radioactive gas that is formed by the breakdown of uranium in soil, rock, and groundwater. It is a colorless and odorless gas that moves freely through the soil and in enclosed spaces, such as buildings, it can accumulate resulting in high concentrations. Radon can enter buildings through cracks in foundation walls and floors, and any gaps around pipes and cables. Radon exposure is known to cause an increased risk of developing lung cancer and is the second leading cause of lung cancer behind smoking. As a result, maximum exposure limits have been established around the…
ASTM E 2178 Standards Explained
The use of the proper air barrier material is an integral part of achieving a resilient and efficient building by protecting it from unwanted air and water penetration. In order for this necessary protection to take place, it is critical that the material be fully tested to ensure that it is able to perform in the environment that it is going to be exposed to. It is key that the selected air barrier material has low air permeance and high resistance. The most common test method to ensure this is ASTM E2178, the Standard Test Method for Air Permeance of…
