Impervius Engineered Coatings The Challenge: The concrete tanks were extremely fractured as improper construction caused failures in the concrete 4 separate concrete tanks were coated for the customer. Each tank contains liquid and solid swine manure; which is extremely acidic and corrosive. Universal Grade from Impervius Engineered Coatings was used on the seams, large cracks and voids. Industrial Grade was them spray applied at an 80 mil (2mm) thickness. No degradation to the coating has occurred from the harsh Hydrogen Sulphide attack. Project is still performing exceptionally well
Under Slab Waterproofing & Methane Barrier Protection Impervius Engineered Coatings was specified in to be a waterproof layer below the concrete slab & also had to be a methane barrier in areas where methane levels were high. Industrial Grade was sprayed on top of pre-cut geotextile at an 80mil (2mm) thickness. The geo-textile had to be cut and placed around the 200 plus penetration on some of the slabs. The project was completed between December 2004 and January 2005 and was on a large municipal Water District treatment plant. The project was the largest infrastructure project in the United States at the time.
