The vibrating steel piles are used for temporary shoring structures type "Soldier pile wall", and are vertically driven trough certain distance with a hydraulic vibrator.

Preliminary drilling for the strengthening structure type "Soldier pile wall" is necessary to be done in the cases of heterogeneous geology (presence of hard layers).

Drilling piles are used to strengthen trench walls, stabilize landslides and other.

Trench slope strengthening with sprayed concrete and soil nails or anchors is fast and flexible method of strengthening.
