Manholes are at a higher risk for I&I than pipelines because they are subject to more surface stresses than sewer pipelines.

With this detailed data, municipalities and contractors can quickly pinpoint areas of deterioration and corrosion leading to I&I and accurately determine a rehabilitation strategy. 

This technique is primarily used in situations where structural cracks have formed allowing groundwater to seep into an otherwise sound manhole/chimney. Grouting fills any voids and helps to create a seal that is watertight.

Cementitious lining products are sprayed (usually with one pass) or applied by trowel. Anti-microbial additives are used because they can offer a wide range of protection against damaging pH and high levels of hydrogen sulfide. 

Bottom line: The restoration and rehabilitation options that are available to restore aging and deteriorating manholes prove to be a cost-effective solution that also helps to extend the service life of the sewer line. It’s a win-win.
