In recent years, geosynthetics have been increasingly used in hydraulic engineering works. The main applications include the rivers banks and bed covering and protection IRIP-RAP and revetments), the construction of synthetic and flexible containers to fill with ag- gregates or sand (bags, mattresses, geotubes and geocontainers), the dams and breakwaters reinforcement, the scour control of all structures laying on the seabed or in contact with the water. GEOSINTEX proposes a new set of solutions for use in these applications. The purpose is to give a complete overview (even if not...

• High tear and compression resistance • Up to 8 tons of filling material capacity • Can contain all types of materials: stones, pebbles, crushed concrete • Guaranteed lifetime of over 50 years, also in seawater Filter Unit is supplied together with a special metal ring joining the 6 connection points of the mesh, thus making it easy to lift. Filter Unit is available in different FILTER UNIT is a container unit (flexible gabion) in polyester yarns, filled with stones, used to consolidate and control the erosion in riverine, marine and all soil stabilization MESH PROPERTIES Raschol mesh...

Place the open Filter Unit in a metal formwork of a predefined size, according to the type Fill it with the excavator bucket or a hopper Close the bag with the appropriate ropes, fix the ring, Lift the Filter Unit with the ring and position it Filter Units can be filled with all kinds of loose material (min size 5 cm): broken stones, pebbles, crushed concrete, coal, etc.

TECHNICAL FEATURES Flexitex is available in two versions: Flexitex FT (Filter Point): this is a double-weave mattress woven together at regular points which act as filters to even out water pressure. Flexitex DT (Distance threads): This double-weave mattress does not have any filter points. The upper and lower sections are connected by means of spa- cing yarns ( distance threads ) to ensure that the concrete-filled mattress is of even thickness. Flexitex DT is available in different thicknesses according to the project specifications. Double-weave mattress (textile shut- tering) made of two...

FLEXITEX is cost-effective, easy to install, it reduces installation times and costs com- pared to the traditional procedures, it can cover areas of up to 700 m2 a day, it is very strong and is supplied in rolls with widths varying from 3.75 to 5.30 m. It also available on panels (sizes upon request) with zip junctions and inlet nozzles. ► GEOSINTEX ALSO SUPPLIES SANDBAG - Flat rectangular bag to be filled in with sand, made of a tubular fabric, open on one short side and closed all around with spe- cial selvedges. Standard dimensions: 1.75 x 2.95 m. Volume: 2 m3. Thickness when filled: ap-...

GEOTEXTILES TUBES TECHNICAL FEATURES Geosintex offers a large range of SintexTube and SintexTube / D: for shoreline application , made from Polypropylene woven geotextile with tensi- le strength of 200 kN/m in both directions, diameter from 1,5 to 5 m and length for shoreline protection, made from woven polyester geotextile needlepunched with nonwoven geotextile, with a tensile strength of 175 kN /m in both directions, diameters from 1.5 to 5 m and length from 10 to 50 m. for dewatering application, made from Polypropylene woven geotextile with ten- sile strength of 70 KN/m in both...

Coastal defense and beach nourishment For this kind of use, SintexTube is filled with sand or dredged materials and acts as a shield against storms, waves, tides and currents. It is are also used as a structure for deviating riv- ers or for flood control. Installed parallel or perpendicular (groins) to the shoreline, they mitigate the energy of the breaking waves and allow the sand transported by the waves to ac- cumulate near the shore, thus contributing to- wards replenishing the beach. ► SintexTube is made from high-strength polypropylene or polyester fabrics, but a special geocompound,...

Transport and storage of dredged materials SintexTube / D is an ideal solution for managing dredged materials. It reduces drainage times and costs and allows dredged sediments to be reused. With SintexTube / D, dewatering can be completed in a matter of days, depending on the characteristics of the sediments. Once dewatered, the weight and volume of the dredged material is reduced, thus making it easier to trans- port to a permanent disposal site. SintexTube / D can be used for the sediments dredged from canals, ports, rivers, reservoirs, detention basins and lakes. This storage system also...
