Manhole Restoration: Coatings to the Rescue

by Kevin Morris

Now more than ever, the sewer collection system is much more vulnerable to corrosive materials that speed the rate of deteroriation. To shed light on the factors that contribute to corrosion in manholes, we were recently featured in the April issue of Trenchless Technology.

The article also provides information on five types of coatings work to prevent corrosion in manholes: cement liners (microsilica mortars and calcium aluminate mortars), epoxy liners (epoxy resin, fiber reinforced and epoxy mortar liners), polyurethane and hybrid polyurea  liners and pure polyurea liners.

Check out the article: “The Role of Coatings in Manhole Restoration.”
