Does CIPP Pose a Health Hazard?

There have been many news stories over the last few years about people in the vicinity of CIPP work falling sick.  Most recently, there was media coverage of schoolchildren and teachers becoming ill shortly after some nearby sewer pipe rehabilitation was performed with a CIPP system.

There have also been studies conducted on the health effects of CIPP, the results of which indicate that there is cause for concern.

Such news coverage gives the impression that CIPP poses health risks to anyone in the vicinity of the work.  However, when you read the newspaper accounts and the studies carefully, you see that each and every incident of illness caused by CIPP cites the use of liners containing volatile organic compounds such as styrene, acetone, and phenol as the likely culprits.

There is no question that VOCs pose a health risk.  Styrene, for instance, is a known irritant of the skin, eyes, and upper respiratory tract.  It was also upgraded last year from “possibly carcinogenic” to “probably carcinogenic”.  The US Environmental Protection Agency warns that phenol exposure and acetone exposure can create a variety of health issues.

The Minnesota Pollution Control Agency notes that in addition to health risks, VOCs also contribute to the creation of smog.

Environmentally-conscious manufacturers of CIPP systems are mindful of the impact their products create.  One such manufacturer is Formadrain. Formadrain liners are made using epoxy resins, not polyester or vinyl ester resins, and contain zero VOCs.  

Offering an environmentally-friendly, no-VOC product is not only the right thing to do, it is also good business.  A study conducted by Unilever reveals that fully a third of consumers are “now buying from brands based on their social and environmental impact”, a result that is confirmed by Uniliver’s own sales of products that have integrated sustainability as compared with those that haven’t.  

A similar study conducted in 2017 by The Conference Board in collaboration with Neilsen revealed similar results.  According to this study, 69% of North American consumers feel that it is very to extremely important that companies implement programs to improve the environment.  Forbes reports that “87% [of American consumers] would buy a product with a social and environmental benefit if given the opportunity”.

The Neilsen report notes that “consumers are using their spending power to effect the change they want to see”.  Given the World Business Council for Sustainable Development’s position that “consumers are increasingly concerned about environmental, social and economic issues, and increasingly willing to act on those concerns”, one could expect this trend to continue.  

Formadrain liners are NSF 14 certified and ICC-ES certified.  The liner’s mechanical properties (flexion and tension) exceed the ASTM F1216 minimum standard by five times.  A 13,000-hour creep test performed by CATT confirms their 50-year modulus of flexural elasticity.

Formadrain licensees are uniquely positioned to offer homeowners and municipalities a premier no-dig product that not only seamlessly rehabilitates pipes to a durable, structurally sound finish but does so at no risk to health or to the environment.
