Definitions
- the invention relates to a watertight sealing of surfaces in water and engineering in particular for traffic routes, tunnels, embankments, soles, channels, dykes, dams, tubs, basins, basements and underground garages with a surface seal in particular from swellable nonwoven, which is located on the surface to be sealed.
- Irrigation or power plant canals, dykes or dams often require waterproofing against water loss. Also seals of underground garages, tunnels or other underground structures need to protect the load-bearing concrete structure from moisture and thus damage to the supporting reinforcement by rust sealing. Bituminous sheets, based on rubber, or plastics such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) or mixtures of these products are used. These seals in turn require protection against damage by built-in soil and / or against the ground.
- PVC polyvinyl chloride
- PE polyethylene
- PP polypropylene
- the known geotextile protective fleeces are only partially suitable against mechanical damage during later construction measures, such as excavations. For long-term protection, they are therefore supplemented by a layer of paving, asphalt or concrete. Paving layers are insensitive and do not stress the seal by expansion or contraction. A additional sealing function, however, requires an expensive and maintenance-intensive sealing of the joints. Due to the simple procurement and a little expensive installation technique, protective layers of concrete have prevailed. In hydraulic engineering, a protective layer laid on the waterproofing seal at the same time takes on the function of a ballast layer against abrasion caused by debris or ice drift, which also prevents damaging UV radiation.
- the object of the invention is to provide a flexible, completely installable seal that does not need to be welded and therefore can be easily installed even under adverse climatic conditions. Also on this seal in embankments protective layers of concrete can be laid without difficulty.
- a cell construction is arranged above the surface seal whose cell walls have strips with sealing effect, in particular of swelling fleece, the cell walls, in particular the fleece strips, standing perpendicularly and / or obliquely on the surface seal and are fastened to one another in a touching manner, and that the cells are filled with concrete or mortar.
- sealing of surfaces according to the invention in water and civil engineering is thus carried out by means of a sealing fleece and its protective layer of concrete, which is divided by a honeycomb or diamond-shaped cell mat made of the same nonwoven material, similar to the geocell known in earthworks.
- an existing seal 2 which lies on the substrate 1 and consists of concrete, asphalt, bitumen or a plastic sheet, webs laid from a known swellable nonwoven and connected by sewing to a full-surface seal the surface to be sealed.
- the preferred basis weight of the dry swellable nonwoven is 400 to 1000 g / m 2 .
- the nonwoven fabric made of synthetic fibers, preferably of polypropylene or polyamide, is impregnated during production with a polymer that swells when water enters, and then dried, resulting in a covering of all the fibers. With the same polymer and the thread used for sewing the single sheets is also equipped.
- the future concrete layer facing side of the sheet-like swellable nonwoven fabric 3 is coated with a film layer of another polymer, which dissolves under the influence of high alkalinity of fresh concrete after a few days. With this coating of the swellable nonwoven, the activation of the swelling agent by the wet concrete is avoided. On the other hand, there is no intensive bond between concrete and fleece.
- swellable nonwoven strip 5a From a stabilized against deformation variant of the swellable nonwoven strip 5a are cut from 10 cm to 50 cm in width. The strips are punctiform or linearly connected to one another at regular intervals so that a diamond-shaped or honeycomb-shaped structure 5 with a surface of 0.2 to 0.5 square meters open between the nonwoven strips is formed with a tensile force applied perpendicular to the strips a mat-shaped cell construction 5 is formed.
- the honeycomb mat 5 produced from the swellable nonwoven strip 5a is unfolded and laid out on the full-surface seal.
- the open areas or cells 7 or spaces are filled with concrete 4, compacted with Rüttelbohlen and smoothed the concrete surface.
- the concrete itself is largely dense. Penetrating water activates the swelling agent in the strip 5a of the honeycomb mat and leads to a sealing of the joint.
- the full-surface laid under the concrete layer swellable nonwoven fabric 3 is partially activated by condensation from the moisture of the soil and already acts as a second sealing layer. If, for any reason, damage occurs in the concrete protection layer, the surface seal in this area is fully activated and the damaged area is completely closed by the swelling pressure of the fleece.
