Trelleborg Drain Internal Joint Seal

Designed to restore joint integrity.

Pipe and manhole joints generally experience higher ground water pressure than the grade adjustment area of a manhole. When infiltration occurs due to deflection, offset or corrosion, the Internal Joint Seal is specifically designed to reestablish watertight conditions.

A = The portion of the seal which covers the pipe or manhole defect
B = The complete width of the seal once installed (includes the band compression area)

Benefits:

• Can be used in concrete, HDPE and most other types of pipe
• Installs easily with torque wrench and socket
• Extension seals available to expand coverage area
• WedgeLock expansion bands create a watertight seal capable of withstanding 10 m of external head pressure
