Geocomposites are georeinforcements that consist of a geogrid and a nonwoven geotextile, which is already firmly attached to grid junctions during the manufacturing phase. Combigrid-geocomposites combine the soil-reinforcing properties of Secugrid-geogrids and the filtering and separating properties of nonwoven geotextiles. The typical application of composite reinforcements is between the subsoil and the structural layer, where it improves the bearing capacity of the structural layer, equalizes differential settlement and filters and keeps the soil layers separate.
As a combination of two products, the advantages of geocomposites are simpler and faster installation; instead of two geosynthetic layers, one layer of installation is sufficient. The advantages are particularly emphasized in soft clays, where the construction of structural layers is challenging. In addition to the benefits of installation, the structure of the geocomposite enhances the reinforcing and strengthening effect compared to two separate products.
