Cherne Shutout seals and lubricates manhole covers to reduce inflow. Shutout is a safe, jobsite ready solution compatible with most manhole installations. It is designed to enhance existing seals by filling voids and defects within the manhole cover and seat. Shoutout creates a water barrier between surfaces, reducing the likelihood of corrosion and lubricating the manhole cover to allow for easier and safer removal. It is easy to transport and requires no measurements or pre-planning. It can be applied easily with minimal surface preparation. Monitor inflow to reapply as needed. Shutout is not compatible with revolutionary access design and some t-gasket manhole installations. Cherne Industries is a global leader in pipe plug and testing.
