This is a follow-up on the 'Demolition' series (Photos 2015-1) to document the building of a new housing estate in the cleared area.
Currently a check dam is built to control groundwater flow. Some photos from the gear are shown below.

The check dam is made by fraising a narrow trench several meters deep and at the same time injecting a fluid cement mixture from the fraise-head, which mingles with the sand. After some time the mixture will harden and a concrete wall has been formed.
The cement mixture is made locally (photo 1..4) and then pumped to the fraising machine as a fluid (photo 5).

The wall is strengthened with steel beams (photo 6) which are lowered vertically into the trench at fixed distances when the cement-sand mixture is still soft. A hole is made in one end of each beam with a torch, allowing it to be hooked up vertically. As far as I know the concrete isn't armored with a steel mesh as usual.
