A method for filling cracks (90) in concrete surfaces (92) using a one- component, hydrophilic polyurethane prepolymer without the addition of any granular impregnating agents is disclosed. The prepolymer is provided in a hand-held aerosol container (60, 200) and is injected into the cracks (90) through hollow injection ports (56) that are adhered (52) in place on the surfaces (92) over the cracks (90) and subsequently closed off (57, 58, 80) when filled. The crack (90) is filled from the bottom up (56) to prevent the formation of air pockets in the crack (90).
L'invention concerne un procédé pour remplir des fissures (90) dans des surfaces en béton (92) à l'aide d'un prépolymère de polyuréthanne hydrophile à un seul composant sans ajout d'agents d'imprégnation granulaires. Le prépolymère est prévu dans un récipient aérosol (60, 200) portatif, et est injecté dans les fissures (90) par des orifices d'injection creux (56) qu'on fixe (52) en place dans les surfaces (92) situées au-dessus des fissures (90), et qui sont ultérieurement obturés (57, 58, 80) une fois remplis. La fissure (90) est remplie du fond jusqu'à la surface (56) pour empêcher la formation de poches d'air dans la fissure (90).
