Abstract: The invention relates to a system for producing an injection silicate gel solution for injection into a soil, comprising a filtering device through which a mixing water can flow for pretreatment, wherein the filtering device comprises at least one filter element for ion exchange, an admixing device for metered admixing of a curing agent, a feeding device for feeding liquid silica sol into the pretreated mixing water, a feeding device for feeding liquid sodium silicate into the pretreated mixing water, and a mixing device for mixing and homogenizing the fed components with the pretreated mixing water for forming an injection silicate gel solution.

Abstract: The invention relates to a method and a device for producing a foundation element in the ground, wherein a hole is formed in the ground which is filled with a hardenable filling mass in order to form the foundation element. According to the invention provision is made in that prior to the hardening of the filling mass a data carrier is introduced into the hole, on which information on the produced foundation element is stored .

Abstract: The invention relates to a method and to a device for creating a foundation element in the ground, wherein ground material is removed by means of a drilling tool and a borehole is created, into which a pile pipe and a curable medium are introduced. The borehole is created having a boring diameter that is greater than an outside diameter of the pile pipe by a specified amount, wherein an annular space is formed between a borehole wall and an outer face of the pile pipe. The removed ground material is conveyed in an interior of the pile pipe, while the annular space is kept substantially free of removed ground material. The curable medium is introduced into the annular space in order to anchor the pile pipe in the ground.
