Securing neighbouring buildings with deeper construction pits.
If a deeper working level is planned next to or near an existing building, underpinning is often required to prevent the building from slipping into the construction pit. Underpinning may also be necessary if a building is to be subsequently deepened to prevent cracking due to soil settlement.
The foundation loads of the existing building with a shallow foundation can be transferred to a deeper foundation level using so-called underpinning bodies. Underpinning can also help to increase the external load-bearing capacity of existing foundations as well as to repair damage due to increased impacts, e.g. as a result of a change of use of the building.
Retrofitting foundations for existing buildings and increasing the load-bearing capacity.
Is there major subsidence in an existing building? Or do larger loads have to be transferred to the subsoil as a result of a planned conversion or a subsequent addition to the building?
Then retrofitting foundations of the existing building to a deeper foundation level is often necessary to ensure that the building remains stable. Through the targeted use of micro piles or the injection of ultra-fine cement, for example, subsequent foundation work can also be carried out in the building and often even during ongoing operations.
