Concrete leveling or concrete raising foams have been marketed recently as an “environmentally friendly” alternative to mudjacking or raising concrete with cement grout.
However, it’s past history of the product resulting in lawsuits, sickness and death tell a different story. Research has shown poly isocyanate to be highly reactive, resulting in self combustion, fire and lawsuits. NIOSH or the National Institute of Occupational Safety and Health, along with the Centers for Disease control or CDC, has documented poly isocyanate products as having health and exposure risks including death.
These facts have been studied and validated by civil and environmental engineers from NJIT. You can research this public information with simple search terms such as: “concrete jacking foam fire” or “lawsuits filed over concrete raising chemical fire”, along with the information provided on the CDC and NIOSH websites.
In addition to known combustion issues, health and occupational related risks, recycle-ability costs and environmental impact of polys or plastics have become a significant concern. This has become apparent with the push for plastic reduction through recent product bans.
While we all know that the control, manufacturing and distribution of a product is good for corporate profits, how good are they for the consumer’s end cost and our environment?
