Multi-Purpose Rubber Composite Adjustment Riser
INFRA-RISER® multi-purpose rubber composite adjustment risers enable the cast iron frame and lid components of manhole and catch basin structures to be easily adjusted to the surrounding road surface.
Created through advanced rubber composite research and proven to withstand extreme conditions, these dynamic components will meet the most stringent application requirements.
INFRA-RISER® rubber composite risers are commonly installed between a concrete manhole structure and EJIW iron castings. These products provide an excellent means to adjust castings to the final road grade surface, prevent groundwater inflow and infiltration into sewer systems, reduce traffic vibration damage to manhole structures, dissipate concentrated load energy, and prolong the service life of our infrastructure.
