Grade rings are precast concrete rings used to raise the top of a manhole to match the surrounding ground or pavement level ensuring the manhole cover is flush with the surface. They are commonly used in sanitary sewer and stormwater manhole assemblies to adjust elevation without cutting into main manhole sections.
These grade rings come in different diameters with thickness adjustments to fit project needs, including options compatible with antimicrobial-treated manholes.
