These piles are built to improve the bearing capacity of the ground. The excavation of the piles is carried out by hydraulic or mechanical punching and after that the equipment is placed and the concrete works are carried out by respectively.

It is possible to encounter certain difficulties in applying methods such as bored pile and mini pile on loose soils of which groundwater levels are high. Contrary to these methods, jet grout is a faster and more economical soil improvement method.

Mini piles have lower capacity than bored piles. Therefore; they are used to transport lower grade of vertical loads. Mini piles are 25-30 cm diameter of pile applications.

This is the process of fixing two building instruments to each other. The steel fixtures are fixed within the concrete structure.

The soil nails are used for providing vertical displacements on deep excavation surfaces or for ensuring slope stability on wall-like structures.

Shotcrete is a method applied by spraying with a high pressure pump a concrete with a finer grain and higher cement ratio to the ceiling and walls in the concrete structure reinforcement projects, to the levels with the danger of sliding during the foundation excavation, to the road slide slopes and in the tunnel constructions.
