The grouting for that team A micropiles is about under gravity. In group B, grout is injected stressed into the outlet, nevertheless the tension is constrained to stop hydrofracturing of the nearby soil. Group C micropiles are mounted in two methods: initial, a Most important grout is strain-placed on hydrofracture the encompassing floor, after which, just ahead of the main grout sets, a secondary grout is injected by way of a manchette tube.
