There has been quite a bit of “buzz” about polyurethane foam otherwise known as Poly lifting/jacking/leveling as a substitute for cementitious grout generally pumped with original traditional mudjacking. Before you jump on that bandwagon, we would like to share some vital information about polyurethane foam that should change your mind. Our sources for this information comes from: www.epa.gov www.osha.gov www.nist.gov www.cdrecycling.org

Polyurethane foam is a byproduct processed from crude oil. Main ingredients are polyois and diisocyanate, both of which are identified as carcinogens and listed as Toxic Substances by EPA. Other ingredients and exposure to its contaminants toluene diisocyanate, methylene chloride, hydrogen cyanide, Iscyanates are known neurotoxins or carcinogens causing cancer in animals. Polyurethane (even best foam) breaks down in 10-12 years under normal conditions.
