Definitions

  • the invention relates to a concrete element for laying in a fluid-tight covering of usable areas, in particular in the form of a paving stone, wall element, one Concrete slab or similar molded component, according to the preamble of Claim 1.
  • the invention addresses the problem of a concrete element of the specified type to create that with reduced Reliable fluid-tight effort with neighboring concrete elements is connectable in a cover and a long-term stable Joint closure favored.
  • the concrete element designed according to the invention is already in the manufacturing plant at predetermined areas of it Side surfaces with a pre-adhesive application Mistake. This pre-order will be relocated corresponding concrete elements aligned so that in Two pre-orders of adhesive reinforcement intended for sealing opposite each other, which then with an in the joint introduced sealing compound a cohesive Establish connection. Such pre-orders can be done with little Effort on largely arbitrarily shaped surfaces the concrete elements are attached and customized different requirements for the respective cover the usable area.
  • the pre-order adhesion promoter consists of a mediation to the concrete mass and primer layer a covering layer of polysulfide, a sealant.
  • the covering ones exist Pre-orders layer after the Laying sealants made of the same material, namely polysulfide.
  • Fig. 1 is an overall designated 1, for example Concrete element designed in the form of a paving stone shown, which is in the installation position (Fig. 2, Fig. 4) to a second concrete element 2 in the area of a Sealing joint 4 adjoins. Lie in this sealing joint 4 the two parts 1 and 2 with their side faces 3 towards each other.
