Abstract: A reticular structure includes first elements distanced from each other and having an elongated conformation according to a first prevalent development trajectory, and second elements distanced from each other and having an elongated conformation according to a second prevalent development trajectory orthogonal, to the first prevalent development trajectory of the first elements. The first and second elements intersect at nodes to form meshes. The first elements have at a mid-portion defined between two consecutive nodes and orthogonally to the first prevalent development trajectory and a substantially T-shaped section including a base and a protuberance emerging orthogonally from the base.

The second elements are stretched along a development thereof, and the second elements are configured such that the net structure exhibits a substantially arched profile and forms a longitudinal seating having an axis of extension substantially parallel to the first elements. A process of manufacturing the reinforcing element and an artificial or partially artificial structure obtained by consolidating the terrain using the reinforcing element are also described.

Abstract: A net structure for geotechnical applications includes a plurality of continuous ribs arranged parallel along an axis of development exhibit; at a first lie plane, a plurality of first continuous filaments, parallel and perpendicular to the ribs; and at a second lie plane, a plurality of second continuous filaments that are parallel to one another. The net structure is monolithic and defines an internal volume comprised between the first and the second lie planes sub-divided by the plurality of ribs into channels that are parallel to one another. The first filaments are defined by laminar structures exhibiting flat surfaces substantially lying in the lie plane, and a plurality of substantially rectangular windows are present at the first and second lie plane.

Anchoring portions extend from the prevalent development plane of the net structure, which anchoring portions, in use condition, are destined to face towards a terrain surface. The elements comprise at least an anti-slip element situated on an opposite side to the anchoring portion with respect to the development plane of the net structure.

Abstract: A product for reinforcing terrain includes a net structure made of a plastic material having a plurality of bars and a plurality of elongate elements that are transversal with respect to the bars. The elongate elements are arranged between adjacent pairs of bars and exhibit a substantially wire-like structure, with a transversal section having a smaller area than a transversal section of the bars. Also described are a use of the product and a method for manufacture thereof.

Abstract: A net for delimiting working areas comprises a laminar structure of plastic material presenting a first prevailing dimension and a second dimension transversal to the first dimension, said laminar structure presenting at least a plurality of lightening perforations defining a plurality of substantially planar longitudinal bands that extend along the first dimension and a plurality of planar transversal bands that extend along the second dimension. The first and second bands intersect at respective nodes to form a plurality of meshes. The first dimension exhibits mechanical tensile strength properties that are similar to mechanical tensile strength properties of the second dimension and the laminar structure exhibits a weight per square metre comprised between 20 g/m2 and 100 g/m2. The laminar structure thus obtained is advantageously realised with a double-stretching stage performed first along the first dimension and then along the second dimension.

Abstract: A process for production of a three-planar net has been conceived, which net consists of a plurality of thread-like elements (2a) of a first series (2) parallel to each other and secured to a plurality of thread-like elements (3a) of a second series (3) parallel to each other and transverse to the elements of the first series (2); the elements (3a) of the second series (3) are in turn secured to elements (4a) of a third series (4) parallel to each other and transverse to the elements of the two first series. The production process contemplates a step of stretching the three-planar-net article thus obtained (10) for modifying the weight features per unit of measurement of the net itself according to the specific requirements.

Abstract: A draining and filtering net, particularly for geotechnical applications, comprising an intermediate layer and a first outer layer and a second outer layer at the mutually opposite faces of the intermediate layer. The particularity of the invention consists in that the intermediate layer and the outer layers are provided monolithically. The intermediate layer is constituted by a plurality of substantially continuous filaments which lie along the extrusion direction. At least one layer of nonwoven fabric is further provided which is connected to one of the outer layers.

Abstract: The present invention relates generally to geo-textiles having an increased resistance to the negative effects of shear forces in installations or layered structures which can be adapted and arranged to utilize geo-textiles. Geo-textiles of the invention comprise at least one high-friction compound, such as one or more high-friction polymers, and methods for making and utilizing them. The high-friction characteristics of components of the invention provide increased resistance to the negative effects of shear forces in layered installations which employ them. Geo-textiles of the invention may have one or more high-friction compounds provided on either or both surfaces. Geo-textiles according to the invention are particularly useful in sloped installations where at least a portion of the layered structure is at a slope angle of greater than 4 degrees, and can be interposed between one or more of geo-membranes, geo-grids, geo-cells, geocomposite laminates and conventional geo-textiles.
