This patented product (made from recycled tires) is a rubber riser, cover, and water seal for use on manholes and valve boxes typically found in city streets.  When a new layer of asphalt pavement is applied to the road surface, the existing manholes need to be re-set to the level of the new asphalt, a costly and time consuming process.  This product is a two-piece system.  The outer piece is bonded to the existing road surface around the manhole.  The inner piece is held in place by a tongue-in-groove/reverse bevel system that allows the inner piece to be removed to gain access to the manhole.  The product then protects the manhole from damage from vehicle impact and helps prevent infiltration of storm water into the sewer system, a major cause of sewage contamination of lakes and streams.
