  • Sealing element for expansion joints
    Patent number: 6751919
    Abstract: A sealing element for the recessed seat of an expansion joint in a concrete structure having an elastomeric profile (20) formed by two longitudinal lateral flanges (21) to be fixed to the end edges of the concrete structure (11), and a central portion (22) formed by walls depending from said flanges and converging to a central area to be fitted inside the seat (12), and shaped to support the hydrostatic pressure upstream of the concrete structure (10). A flexible duct (30) is installed inside the seat (12) below the central portion central area and provided with radial bores (31) opened to the inside of the seat to allow the selective feeding of precatalyzed polymeric resin to the inside of the seat (12), after the elastomeric profile (20) has been mounted and affixed to the concrete structure (10). The tube can be separate from the profile, attached to the central area, or the central area can have a W shape and the tube be within the lower portion of the W.
