Definitions

  • cement or concrete structures (hereinafter, we will most often only use the word cement to simplify) frequently exhibit water tightness losses caused by porosities and by cracks generated by developing mechanical stresses in use.
  • the present material provides a satisfactory answer to this technical problem.
  • This material is characterized in that it is a complex composed: of a textile support made of synthetic threads, into which a monofilament of synthetic material has been inserted, during its manufacture, forming rows of loops erected perpendicularly on the reverse side of the support, and of a coating of plastomer or elastomer deposited on the support and giving it sealing and resistance to aggressive agents.
  • the textile support can be woven, but it is preferably knitted, knitting giving the textile support, and consequently the complex, better elasticity. allowing to better follow the variations in shape of the cement structure and the joints, due to the constraints to which they may be subjected. You can use, for example, Raschel warp knitting, double closed-link weaving, with four bars, plus one bar for binding the monofilament.
  • the basic texture of the fabric obtained by this process is particularly suitable for keeping the loops upright; it blocks them in this position.
  • a suitable fabric is that manufactured by any knitting or weaving method providing a fabric of good elasticity (without permanent deformation) and ensuring good stability of the shape and the erected position of the loops under stress. It is also advisable to choose the material of the monofilament constituting the loops so that it contributes to ensuring said stability.
  • the application of the coating to the textile support is carried out by conventional methods.
  • the transfer coating process may be mentioned, by way of example: the non-gelled plastic material is spread on a temporary support such as a paper coated with an anti-adhesion substance; the fabric is placed on the plastic by unrolling it while exerting just enough pressure so that the loops, located on the face of the fabric opposite to that which is in contact with the plastic, do not penetrate into it; the plastic is then gelled by passing the complex through a tunnel, heated to 180-190 ° for example in the case of polyvinyl chloride, the complex is cooled, then the temporary support is removed.
  • the textile support can be made of synthetic polyester, polyamide, polypropylene and similar yarns.
  • the synthetic monofilament can be polyamide, polyester, polyolefin, polyvinylidene chloride and the like.
  • the coating it can be, for example, made of flexible polyvinyl chloride, polyolefin, EPDM terpolymer (ethylene-propylene-diene monomers), "Butyl” rubber (isobutylene-isoprene copolymer).
  • the loops sink into the fresh cement and anchor there during setting; after complete setting, the resistance to tearing developed is opposed to any separation.
  • the elasticity and mechanical strength of the complex allow it to absorb stresses, without failure of the seal.
  • the sealing material according to the invention is applicable, by its reverse side covered with erect loops, on any cement surface to be sealed, whether it is flat, curved, horizontal, vertical or oblique.
  • Other nonlimiting examples are tanks, basins, cisterns, canals, pipes, pipes and the like made of concrete or cement.
  • the method of laying the material is as follows, in the general case: the complex is unrolled on the surface of fresh cement to be sealed and it is smoothed with a roller or a large squeegee, to avoid air pockets and to push the loops in the cement.
  • a covering strip textile sheet or support, coated with plastomer or elastomer on its two faces and glued or welded to said coating of the material in said junction zones.
  • the strips and sheets can be stored in rolls and have any size suitable for their destination.
  • the material consists of a textile support 1 having alignments of erected loops 2. It is a knitted fabric, obtained by the particular knitting method mentioned above.
  • a plastomer or elastomer coating 3 doubles the textile support, on its face opposite to that covered with loops.
  • this knitted fabric may have the following characteristics: 35 stitches in decimetre, mass of the fabric before depositing the coating 135 g / m2, thickness approximately 0.8 mm, and the coating may have above the fabric a thickness of the order of 1 mm, which can however vary between a few tenths of a millimeter and 2 mm.
  • the fabric may be polyester with polyamide monofilament loops and the covering may be plasticized polyvinyl chloride.
  • the loops can have a height above the fabric of about 1 to 3 mm and the space between them can be 2 to 3 mm. All these values are in no way limiting.
