Process for lining construction spaces, in particular shafts, galleries, tunnels or the like

摘要

The invention relates to a process for lining construction spaces, in particular shafts, galleries, tunnels or the like, in which firstly a waterproofing layer is applied directly onto the rock and then a sprayed concrete layer is applied onto the waterproofing layer. In order to achieve a uniform single-shell construction without time and cost expenditure, a plastics layer consisting of a fast-reacting modified two-component plastics as waterproofing layer is sprayed onto the rock by the two-component spraying process.
