... form the lining of tunnels (train, metro, road, piping, water...). The process involves lining the tunnels with rings of concrete made up of 6 to 8 voussoirs connected to each other. Generally, modern support methods are sufficient to ensure the permanent stability of the excavation in rocky masses. However, some terrains evolve over time (swelling, mineral creep, consolidation of clays...). In this case, it is necessary to assemble voussoirs to form a durable lining...

... dissolves quickly to allow for the rapid opening of the bag. Tie with a single loop. The bag is soluble in hot water, allowing for the collection of wet laundry (precautions should be taken by lining the walls of the bag with dry laundry). The washing machine or tunnel should not be overloaded to ensure proper water circulation and effective dissolution of the tie and bag. Improper use may lead to material residues.
