Overview Ground Improvement

Ground improvement increases the load-bearing capacity and reduces settlements. The risk of soil liquefaction during earthquakes can also be reduced. The resulting foundation conditions are equivalent to those of natural soils with an adequate load-bearing capacity. Ground improvement involves the use of self-exploratory processes. An intrinsic adaptation of achievable depths and diameters occurs as a result of changing geological parameters.

Vibroflotation (VF)

Applicable in granular to weakly cohesive soils, such as sand and gravel, as well as in slag deposits. Suitable for high loads on the improved subsoil including dynamic stress. Very low settlements. Particularly economical in saturated soils below the groundwater level.

Vibro Displacement (VD)

Applicable in mixed-grained soils, such as sandy silts to cohesive soils with an undrained shear strength of 20 to 80 kN/m2 by the addition of coarse granular backfill. Suitable for light to medium building loads.

Vibro Concrete Columns (VCC)

Can be used in primarily soft cohesive soils as well as organic deposits overlying load-bearing soil formations. Suitable for both light and medium building loads. Very low settlements.

Bauer Dynamic Compaction (BDC)

BDC (Bauer Dynamic Compaction) is particularly suited for increasing the relative density of non-cohesive granular soils and loose mixed soils with low fines content. The process involves dropping a heavy weight (pounder) repeatedly on the ground at regularly spaced impact points. The kinetic energy released on impact penetrates into deeper soil formations and, as a result of the forced rearrangement of the soil particles, leads to compaction.

The degree of compaction depends on the mass of the drop weight, the drop height and the spacing of the impact points. BDC is mainly used on fill, demolition waste and building rubble, as well as soil formations with large voids (karst).
