Making sure your manhole assembly is to final grade with the road surface is an essential part of a new manhole installation, rehabilitation, or road resurfacing project. The INFRA-RISER® multi-purpose rubber composite adjustment riser by EJ is engineered to adjust manhole covers and catch basins to grade. It’s a simple, economic, and long-lasting solution that separates the surfaces of the manhole structure and access assembly, preventing water infiltration and traffic vibration damage to the structure. Made in the USA from 92% recycled materials.
