INFRA-RISER® rubber composite adjustment risers reduce traffic vibration damage — prolonging the life of access structures and surrounding pavement. A simple, economic, efficient, and long-lasting solution, INFRA-RISER dissipates the energy transferred between the casting and the manhole structure. It protects against load concentration stress and dramatically reduces water infiltration. Available in a wide variety of shapes and sizes, they are also offered in flat or tapered styles to help perfect sloped grades. An innovative solution, this environmentally-friendly product consists of 92% recycled raw material, made from recycled tires and fortifying additives. EJ products are often used by architects and engineers to help earn points toward achieving LEED certification for their green or sustainable construction projects.
Riser rings are an adjustable solution to bring a manhole or catch basin to grade on your resurfacing projects. They are used in conjunction with a frame to increase its overall height. A typical application would be during pavement overlays. Cast iron or steel riser rings are offered as a solid ring type, and the steel versions are also available in an adjustable-diameter style. Optional sloped risers are for applications such as roads with a crowned grade. Load tested to ensure dependable strength and long lasting durability — DOT approved in many states.
