CIPP and Spray-On Liner Culvert Rehabilitation: A Review of Water Quality Impacts and Current Construction Specifications

Cured-in-place-pipe (CIPP) and spray-on liners are used to rehabilitate damaged culverts because they can be less expensive than other pipe repair technologies. Study objectives were to: (1) compile and summarize known CIPP and spray-on lining surface water contamination incidents; (2) provide an overview of water quality impact studies on CIPP and spray-on liners; (3) compare and contrast current transportation agency construction practices. The literature was reviewed for contamination incidents and water quality impact studies. Construction documents and perspectives were obtained from 32 DOTs. Twelve CIPP surface water contamination incidents were found while none were found for spray-on liners. CIPP incidents were attributed to the release of uncured resin, manufacturing byproducts, and waste to surface waters. Four states conducted water quality impact field studies for CIPP, while only 1 state examined spray-on liners. Studies revealed that CIPP installations released resin ingredients, solvents, and manufacturing byproducts. Chemicals were detected in water samples for up to 88 days. Although no water quality impacts were found from field tests of cementitious and polyurea spray-on liners, impacts to water quality were found in laboratory tests. Many (22) states had CIPP construction guidance while only three had spray-on liner guidance. Construction requirements included the temporary use of materials at the culvert openings to limit chemical release; water testing before and after liner installation; and the capture and authorized release of wastewater. The report provides a list of recommended construction specifications to minimize risks to water quality.
