Construction Drilling has successfully tremie-poured thousands of drilled shafts and piles. Tremie concrete placement uses a pipe through which concrete is placed below water. Tremie pipe is also used to place concrete that would otherwise fall a great distance from the concrete discharge point at the top of the shaft to the concrete placement point at the bottom of the shaft.
Tremie pipe is used to prevent segregation when concrete is placed underwater. Concrete can be carefully placed in a compact mass at its final position by means of a tremie pipe (see Figure 1), and is not disturbed after being deposited. Specialized mix designs have to be used to ensure concrete flows through the reinforcing steel cage. Construction Drilling can develop a tremie pour procedure specific to your project and tailored to your project specifications. Additionally, we can assist with the development of your concrete mix design.
