Subgrade stabilization

Pillar/deep stabilization is a method of subgrade stabilization often used for soft foundation soil as well as for roads, fields, gardens, and streets.

Mass stabilization is a mass subgrade stabilization method for soft and argillaceous silt land, in which it is possible to replace as much as 4-5 metres of solid mass. The method conserves non-renewable natural gravel resources.

Georeinforcement is used in diverse forms as additional stabilization for ramps and bearing strata as well as together with piling and stabilizers.

Tb-piling is the traditional method of subgrade stabilization, such as in a street building and at construction sites.

Pile slabs are used as a method in demanding, completely rigid structures to stabilize the subgrade of heavily loaded roads, railways, and fields.

In the relief method, the materials used most are light gravel and plastic relief plates such as styrox.

Pipe and drill piles are methods for stabilizing heavily loaded and used roads and bridge structures.

In situ piles are usually used at sites requiring large point loading such as in bridges and machine foundations.

Abutment walls are in most cases realized on steel butments in building pits.

Anchoring is used to support excavations and for tensioning buildings, including against buoyant force. Anchoring is either permanent or temporary.

The deep compaction method, as realized using a monkey engine, is a method of improving the bearing capacity of thick, loose, non-cohesive soil.
