All methods of placing concrete under water are designed to prevent cement washout and the consequent forma-tion of weakly cemented sand and gravel pockets. In the tremie pro c e s s, concrete is placed through a ve r tical steel pipe with an open, funnel-shaped upper end.

What is a Tremie?

The tremie method is also used to seal underground well casings. Sealing around the well with concrete or grout prevents the well from caving in on itself, and also keeps unwanted surface water from contaminating the water supply. The tremie pumps wet concrete into the base around the well casing until the mixture reaches ground level.

Tremie - Wikipedia

A tremie is a watertight pipe, usually of about 250 mm inside diameter (150 to 300 mm), with a conical hopper at its upper end above the water level. It may have a loose plug or a valve at the bottom end. 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.

The most common way to obtain accurate measurements of concrete volume is to utilize truck tickets, with the volume of concrete in the tremie or pump lines estimated and subtracted from the total. If there is a stroke counter on a pump, it may be used to estimate volume pumped, but only if the volume per stroke is calibrated.
