Tremie concrete is a method used in construction to place concrete underwater or below the waterline. This technique involves using a tremie pipe, which is a large, flexible tube that is lowered into the water or into a borehole to deliver the concrete to its intended location. The concrete is poured into the top of the tremie pipe and allowed to flow down through the pipe to the bottom, displacing the water as it goes. This ensures that the concrete is placed in a controlled and efficient manner without any segregation or contamination from the water.Tremie concrete is commonly used in the construction of foundations for bridges, dams, and other structures that require underwater concrete placement. This method is preferred in situations where traditional methods of pouring concrete, such
