Tremie - Wikipedia

The tremie is often supported by a working platform above the water level. The pipe is made up of short sections commonly joined by screw thread with O-ring seal so that the length can be adjusted during the pour without getting the top of the pipe below the water or removing the bottom end from below the surface of the poured concrete. To facilitate management of pipe length it may be built up from 1 to 3.5m sections. A foam rubber 'pig' may be used to plug the pipe while introducing the first batch of concrete.
