The Lifespan System® is a watertight, corrosion-proof, non-conductive, locking rubber manhole frame and cover system that prevents rain derived inflow from entering sanitary sewers through the top of the manhole.
Features & Benefits
The Lifespan System® is specifically designed to eliminate unwanted flows at the cover and chimney area; and retain the hydraulic, watertight and structural integrity of the underlying concrete structure, thereby delivering an extended service life.
Made of the same ultra high-performance rubber materials that have been used in sanitary sewers and on transportation projects for more than 50 years, on such applications as bridge bearing pads and expansion joints on roadways and parking structures.
The Lifespan System® has been field-proven since 2006 in some extremely harsh city road environments, including Montreal, Canada and Naperville, IL, where air temperatures can range from -25o F to 104o F (-32o C to +40o C).
SHURE-LOK alignment system
The Lifespan System® utilizes the SHURE-LOK alignment system to ensure proper alignment of the cover to the frame and proper locking of the cover to the frame.
The Lifespan System® absorbs impact, so the system and surrounding pavement remain intact. This saves on costly road repairs associated with cast iron systems.
