Risers are a cost effective solution for your road and utility maintenance needs. Risers address a major dilemma facing today’s street maintenance departments by raising manhole castings to grade quickly and inexpensively, yet permanently. Manhole risers can help to absorb the constant impact of traffic hitting the top of the manhole frame. Without them, you will end up with manholes that are below the surface, which can cause damage to vehicles, bikers or snowplows.
