At Pipe-Eye, our technicians can rehabilitate manhole structures through application of specific cementitious coatings. Many corrosive compounds found in the wastewater collection system, such as hydrogen sulfide, can have a detrimental effect on manholes. Our crews can apply a specific blend of cementitious coatings on the interior of manholes to easily restore structural integrity, in some cases without even entering the manhole. When combined with chemical grout injection, the end result is a strong, infiltration-free environment at a fraction of replacement costs.
