A method of sealing cracks or gaps in concrete structural elements

摘要

The invention relates to a method for sealing off of cracks (1) or joints in concrete structural elements (2) with the following steps:a) preparation of the surface of the concrete component (2) in the region of the crack (1) or of the joint to remove loose or not load-bearing parts;b) introducing at least one of a surface (3) of the concrete component (2) to the crack (1) or of the gap, leading to the oblique bore (4) in the concrete structural element (2);c) injection of a sealing means (6) in the oblique bore (4) for the filling of the crack (1) or of the joint with the sealing means (6) up to saturation;d) applying a primer (7) on the surface (3) of the concrete component (2) in the region of the crack (1) or of the joint;e) applying a first cover layer (8) on the primer (7);f) the application of a grating belt or plastic web (8) on the first covering layer (8) andg) applying a second cover layer (10) on the grating belt or plastic nonwoven fabric (8).
