AR 800 in action

Here’s what a curtain grouting job looks like mid-way. This is the basement of a high-rise apartment building in NYC that is having voids filled behind the wall and leaks sealed with our AR 800 acrylate grout. Why did they choose AR 800 vs a polyurethane foam like Prime Flex 920? There is an old heating oil tank behind the wall, so they have to be careful about crushing and rupturing that tank. AR 800 produces an elastomeric gel that does not create expansive pressure, and excels in wet environments, making it an ideal choice for this scenario. See that black substance oozing from the ports? That is heating oil that contaminates the soil. The AR 800 is still curing beautifully in the presence of the oil.basement wall grouted with AR 800 acrylate
