The Lifespan® System Frame components are made of the same high-performance rubber that has been used to seal sewer pipes and manholes for more than 70 years. Designed for areas experiencing the highest degrees of inflow and infiltration, you have a watertight, corrosion-proof, and highly durable frame which is applied at the top of the collection system that has the added benefits of being extremely lightweight when compared to traditional cast-iron frame and cover systems.

Suitable for use in either new or rehabilitation installations, The Lifespan® System is designed to retain the hydraulic, watertight and structural integrity of the underlying concrete structure and delivers a much longer service life than traditional cast-iron frame and cover systems. This means, when considering elimination of maintenance needs and reduced sewer treatment costs, the life cycle cost of Lifespan® will be lower than other systems.
