In civil engineering, complex, multi-layer challenges often arise where the different functions of various product groups are required simultaneously in one application. In earthworks for road and traffic route construction, geosynthetics are used for separating, filtering, draining, reinforcing, protecting and sealing. In order to be able to fulfil several of these functions simultaneously for certain applications, a wide variety of geocomposites have been developed over the years.
As the name suggests, geocomposites are created by combining several individual geosynthetics or by combining a geosynthetic with other materials. The result is a particularly high-performance geosynthetic composite that combines two or more functions in a single product. In addition to the obvious technical advantages, there are also economic aspects to consider. Combination products offer significant potential savings during installation, since only one instead of several individual products has to be laid, which means that several work steps can be eliminated.
Composites or combination products usually have the technical properties and perform the functions of the products from which they are made. Their areas of application are the same as those of the individual products. Drainage composites such as drainage grids, drainage mats and drainage membranes are some of the most familiar geocomposites. Here the functions of filtering, separating and draining are combined in one product. The geosynthetic drainage layer takes on the task of draining away water. The non-woven fabrics that are bonded to one or both sides of the drainage layer in the factory act as a separating and filtering medium in relation to the soil.
Combinations of geogrids with non-wovens for soil stabilisation are also very successful geocomposites. In this type of application, a separating and filtering non-woven fabric is often required in addition to the reinforcing geogrid. Both functional layers are installed in a single combined product, in just one work step instead of two. This saves time and resources and also the environment.
All products in the range Geocomposites
BEGRID TG Geogrid
Geogrids in the BEGRID TG range are made of high-quality polypropylene (PP). They are monolithic, biaxially stretched and have rigid nodes. This structure makes BEGRID TG geogrids extremely robust and resilient.
BEDRAIN Drainage Grids
BEDRAIN Drainage Grids are pressure-resistant drainage grids made of high-density polyethylene (HDPE) with non-woven fabric bonded on one or both sides, specifically for use in drainage applications under high compressive loading.
BEDRAIN Drainage Mats
BEDRAIN Drainage Mats comprise a three-dimensional random arrangement of polypropylene (PP) monofilaments. They are used for drainage, as surface drainage systems, in green roofs, for foundation wall protection, in landfill sites and in tunnel construction.
BEGREEN steep slope systems
BEGREEN is an embankment protection system for inclinations of up to 70°. The system is based on laying layers of soil and geogrids alternately, whereby the geogrid acts as a structural reinforcement element.
BEMAT Erosion Control Mats
BEMAT erosion control mats are three-dimensional non-woven mats made of randomly arranged polypropylene (PP) monofilaments. As the vegetation starts to grow, the mats prevent erosion channels from forming, fix the soil in place and secure it against leaching.
BENTOMAT Geosynthetic Clay Liners
Geosynthetic clay liners, also known as bentonite mats, are composite geotextile materials that have been in use for many years as a successful natural method for sealing against liquids and gases in a wide variety of applications.
CONCRETE CANVAS concrete mats
CONCRETE CANVAS brings together many advantages in one product: the robustness, fire resistance and durability of concrete combined with the excellent abrasion resistance and sealing properties of the geosynthetics.
TERRAMESH steep slope systems
The reinforcing material in TERRAMESH systems comprises a mesh made of double twisted steel wire. The wire has duplex protection, consisting of a thick galvanised GalMac alloy coating and an additional Galmac coating.
Droptec Protection and Drainage Membrane
DROPTEC is a high-quality protection and drainage membrane with a bonded non-woven filter layer; for use in difficult drainage situations in intensive and extensive green roof systems on flat roofs. The protection and drainage membranes form part of the green roof system.
