Abstract (en)
[origin: WO0012863A1] The invention relates to a method for sealing construction works, walls and hollow cavities embodied in ground, rock or mountains, notably tunnels, mine galleries, shafts, canals or caverns. According to said method a sealant material is introduced into the rock (1) under pressure via a sealed bore hole (2). Heated melted materials presenting low viscosity and high initial strength, notably polyamides or gels having polyamide-like properties, are injected under pressure into the rock (1) or building material via the bore hole (2) so that they penetrate cracks and pores in the rock (1) or building material to be sealed. After cooling, said cracks and pores are permanently and hermetically sealed.
