The grouting with the group A micropiles is ready below gravity. In team B, grout is injected under pressure into the hole, nevertheless the tension is constrained to forestall hydrofracturing of the nearby soil. Team C micropiles are mounted in two measures: very first, a Main grout is strain-applied to hydrofracture the surrounding ground, and afterwards, just ahead of the major grout sets, a secondary grout is injected via a manchette tube.
a) Micropiles can be engaged in any challenging problems involving soil and rock.. b) Micropiles is usually customised and applied for hard terrains and programs. The apps can possibly be in the form of new loads currently being extra to an present structure.

Other internet site situations that make micropiles interesting are: obstructions, massive cobbles or boulders, nearby sensitive buildings, karst topography or large groundwater problems.
In these sorts of piles, tension grouting is accompanied by tremie grouting. On completion of tension grouting, a worldwide injection grouting is carried out via a pre-set up sleeve port pipe. This grouting shall be done before the hardening of Main tremie grout.
