The Mainstay Composite Liner Versus Mortar Followed By a Protective Coating

The Mainstay Composite Liner is essentially simultaneously applied to the corroded manhole and finished in as little as a few hours to produce a tightly bonded, continuous lining. Competitive mortars often must be allowed to cure prior to topcoating, which extends the restoration process by at least one day and requires an additional mobilization to perform the work. Another significant drawback to allowing the mortar to cure is that the manhole surface may become contaminated and/or damp, requiring additional cleaning and drying.

The Mainstay Composite Liner Versus A Coating Alone

The Mainstay Composite Liner repairs deteriorated concrete and brick manholes and also provides a smooth surface for the application of a protective coating. The restoration mortar restores structural integrity, seals rough and deteriorated surfaces, and is not affected by dampness and external hydrostatic water pressure. A coating-only system, on the other hand, may exhibit numerous discontinuities if applied to an untreated, rough substrate. Furthermore, coating-only systems may face adhesion problems due to the dampness inherent in subterranean concrete and brick structures such as manholes. The Mainstay Composite Liner provides structural enhancement and corrosion resistance. A coating alone, even if the material by itself has high compressive and flexural strengths, does not provide structural enhancement.
