Top Hat pre-forms should be used to provide an effective seal around service pipe penetrations.

Full Description

Twinwall top hat connectors are available in 110mm or 225mm and are used for connecting inlet, outlet and vent pipes through impermeable membrane liners.

Top hats are typically bonded to the membrane layer using a double-sided duty tape between the top hat and the membrane, and 75mm PVC tape around the perimeter of the top hat.

These top hats are used as part of an attenuation and infiltration system where pipes enter the crate in order to create sustainable urban drainage solutions (SUDS).
