Method of lining and repairing underground constructions such as shafts and tunnels with a lining material suitable for casting, whereby at least one elastic mould part is placed inside the shaft. The mould part is fixed longitudinally in the shaft, after which it expands to a predetermined shape through the addition of a medium inside it and the lining material is added between the mould part and the wall of the shaft. Once the lining material has set, the medium is removed from the mould art, after which the mould part is removed. In order to carry out this method, the mould part comprises a container of elastic material exhibiting a predetermined shape when in an expanded state, which is placed and fixed in the shaft, and devices for adding a medium to the mould part and expanding it. |
