Cretex Specialty Products provides flexible, mechanical internal and external manhole frame-chimney seals for use on sanitary sewer manholes. The seals stop manhole frame-chimney inflow and infiltration, creating a durable seal for the top of a manhole. The company also offers internal manhole and pipe joint seals, external joint wraps, lid plugs, lid gaskets and inflow dishes to prevent leakage of water into manholes.
