Our activities in hydraulic engineering

Our origins was founded in the hydraulic engineering, about 70 years ago.

Geopex originated from a company that originally produced reed mats, which were also used as filter mats for the temporary protection of newly constructed river banks.

The development of synthetic geotextiles and their application in hydraulic engineering works, partly caused by the flood disaster in 1953, ensured that Geopex developed into an expert supplier of geotextiles in the many applications that hydraulic engineering has.

 

Geotextiles for facsine mattresses for shore and bottom protection,

Due to their good filtering properties, combined with a hith tensile strength and a long lifetime, synthetic geotextiles are frequently used in filter matresses with facsines, which will protect the waterbed and the slope of a dike against erosion.

In addition to a wide range of filter fabrics, GEOPEX also has the knowledge and specialized machinery to produce various types of composites in-house.

Filters in slope constructions

The use of geotextiles as filters is possibly the oldest and most common use. The combination of the correct pore size and water permeability prevents leaching of the fine soil parts, but also ensures that excess water is drained from the structure.

Geopex has the right product for every specific application. This can be a woven fabric, a non woven filter or a combination of both.

 

 

Advice on design

Over the years, due to experiences and new insights, the requirements for hydraulic structures are continuously changing. Geopex follows these developments closely and is involved in the development of design guidelines, such as the latest CROW-CUR design guideline “Geotextiles under Stone Revetments”. We are also familiar with the Erratum of this design directive.

We are also involved in various studies and researches, as drop tests, to help you make the right choice in your design or project.

 

For this application Geopex has the following geotextiles in its assortment:

Woven geotextiles

Woven fabrics are characterized by a high tensile strength in combination with a low elongation. This makes them suitable for use in facsine matresses for shore and bottom protection, where strength is required during installation. They also have good filter properties.

The PP fabrics are also available with woven-in loops.

Non woven geotextiles

Nonwovens do have a high elongation and are therefore able to absorb deformations caused by, for example, stone droppings. They have a very good filter effect, a small pore size in combination with high water permeability.

 

 

 

Geocomposites, a combination of both

Geocomposites combine the good properties of both woven and nonwoven geotextiles. We also produce composites with a geomembrane to perform a water-retaining function and composites with a natural layer, such as reed or jute.
