What Does Rebated Joint Mean?

A rebated joint is a recess, groove or notch cut into the end of a concrete pipe (or any other machinable material) to facilitate the fitting of another pipe into the joint. These types of joints are often used in precast reinforced concrete pipes to join one or more sections of pipe.

A rebated joint is also known as a lip joint or lip connection.


Trenchlesspedia Explains Rebated Joint

Rebated joints have widely replaced butt joints (joints with no integrated sockets). These types of joints are commonly seen in precast pipes during pipe jacking operations. Once the first section of pipe has been advanced far enough by the hydraulic jacks, another section of pipe is inserted into the launch shaft and fit into the rebated joint of the pipe before it (similar to a jigsaw puzzle).

Because of the demand for water tightness, especially in underground pipes and sewers, rebated joints require special attention to sealing and waterproofing.
