METHOD FOR WATERPROOFING UNDERGROUND STRUCTURES

摘要

A method for water-proofing underground structures (10) comprising: a step of injecting an expanding compound adjacent to the surface (10b) directed toward the outside of an underground structure (10) to be waterproofed in order to form at least two confinement portions (2); a step of injecting a diffusing compound (4) intended to harden adjacent to the surface (10a) directed toward the outside of the underground structure (10) and at a completion region (3) that is delimited by said at least two confinement portions (2).
