In percussion drilling, pipes or drill rods are driven into the ground through repeated impact – ideal for load-bearing foundations in difficult soil conditions. In rotary drilling, the drill string is rotated to loosen and remove soil. This method is particularly suitable for deeper boreholes and soft to medium soil types. Both methods are central techniques in special foundation engineering and enable precise, safe work even under demanding conditions.

In single auger drilling, a single drill auger is used that continuously transports the soil material upward. This method is particularly suitable for stable soils and enables precise, clean drilling for pile foundations and pipe installations.

Dual-head drilling uses two drill heads simultaneously to achieve tight spacing between piles or structures. Overburden drilling allows drilling beneath existing buildings or infrastructure without affecting them. Both methods offer high flexibility for complex special foundation projects.

In geothermal and ground source drilling, deep boreholes are created to extract heat from the ground. The method requires precise drilling and stable drill pipes to enable long-term energy extraction from the subsurface.
