Abstract
Foundation, apparatus and method for stabilization of a foundation. The foundation comprises a subsoil and a pavement structure formed over it, which pavement structure includes a plurality of successive structural layers. At least one of these structural layers is a binder-stabilized structural layer which includes stone material and a binder. Additionally, the stabilized structural layer is enclosed within a sleeve structure.
Claims27
A foundation, comprising:
- a subsoil;
- a pavement structure formed over the subsoil and comprising a plurality of successive structural layers;
- and wherein at least one of said structural layers is stabilized by means of at least one hardenable binder and forms a binder-stabilization layer;
- and further, wherein at least one of said binder-stabilization layers of the pavement structure is enclosed within a sleeve structure, the sleeve structure comprises two superposed films extending in a longitudinal direction of the foundation, the longitudinal edges of which films are closed and between which films the material treated with a hardenable binder is arranged;
- wherein
- the binder-stabilization layer arranged inside the sleeve structure is of a geopolymer or an alkali-activatable hardenable mixture;
- and wherein the compression strength of the binder-stabilization layer arranged inside the sleeve structure is at least 0.1 Mpa.

A method for stabilization of a foundation, in which method the foundation is treated with at least one stabilizing material to improve its compression strength;
- and a stabilized structural layer of the foundation is arranged in a space delimited by a sleeve structure;
- wherein
- a geopolymer or an alkali-activatable mixture is used for stabilizing stone material, and wherein stone material is taken from the foundation;
- the stone material is treated with a hardenable binder;
- the stabilization-treated stone material is fed into a space delimited by a sleeve structure;
- and
- the taken stone material is returned back to the foundation after the treatment.

- and wherein at least one of said structural layers is stabilized by means of at least one hardenable binder and forms a binder-stabilization layer;
- and further, wherein at least one of said binder-stabilization layers of the pavement structure is enclosed within a sleeve structure, and wherein the sleeve structure comprises a film extending in the longitudinal direction of the foundation, longitudinal edges of which film are folded together and fixed to each other, whereby a tubular shape having a closed cross-section is formed;
- wherein
- the binder-stabilization layer arranged inside the sleeve structure is of a geopolymer or an alkali-activatable hardenable mixture;
- and wherein the compression strength of the binder-stabilization layer arranged inside the sleeve structure is at least 0.1 Mpa.
