When to Use Tremie?

A tremie is a pipe that can be used for pouring concrete below ground level, often underwater. Common applications include piling works, basements, diaphragm walls, caissons, underwater foundations, and so on.

What is the reason for using a tremie tube for concrete placement?

A tremie is used to pour concrete underwater in a way that avoids washout of cement from the mix due to turbulent water contact with the concrete while it is flowing. This produces a more reliable strength of the product.

How do you use a tremie pipe?

The lower end of the tremie pipe must be closed with a check valve before inserting it into the water. After that, freshly mixed concrete is poured with the help of hopper. When the concrete is poured, it displaces the air and water present in the pipe and finally reaches to the bed.
