A single seal cover can be airtight when the groove is filled with grease or other suitable sealing compounds. It will prevent gases from drain manholes escaping to the surface. These covers are usually used in residential or commercial areas. A double-seal manhole cover has double the arrangement of a single-seal cover. This creates an airtight and a water-tight seal. This feature is guaranteed to prevent gas escape, and the seepage of surface water through the cover, thus causing damage to the underground utilities within the chamber.
