Micropiles got their name due to the size and dimensions of the equipment for their execution.
These are the same injection or bored piles, only of smaller diameters and lengths, which makes them indispensable when performing small volumes of work, working in conditions of limited space (making piles for strengthening foundations, piles in the middle of existing buildings, and the like), but specialized piles are already added to this family – soil-cement (increasing the bearing capacity of soils by cementing existing soils without replacing them), jet grouting (drilling a pipe with nozzles to the design depth and injecting cement mortar under high pressure with gradual removal and rotation of the drilling tool).
For the execution of micropiles, fundamentally different tools are used, depending on the tasks and conditions (electric drilling rigs, hydraulic drills based on excavators, drilling rigs on crawler chassis and specialized micro-drilling rigs). Soil anchors can also be classified as micropiles. They are not used for laying foundations, but are intended to support vertical (sloping, sliding, and similar) structures. Most often, soil anchors are used to hold retaining walls or to perform anti-slide measures.
