Combigrid® geocomposites benefit from NAUE’s decades of reinforcement experience
Combigrid® geocomposites benefit from NAUE’s decades of reinforcement experience. Continuous improvement of the manufacturing process, stringent quality control in raw material selec- tion and expert engineering support ensure safe and economical constructions.
Combigrid® is a geocomposite reinforcement solution. The unique manufacturing process produces structured, high strength, monolithic, pre-stressed polypropylene or polyester reinforcing bars with a continuous molecular structure. The extraordinary high extensional stiffness of Combigrid® efficiently reduces deformations in the subgrade which extends the service life of modern infrastructure.
The geocomposite additionally embeds a Secutex® nonwoven geotextile within the reinforcing bars. The welding process that strongly joins the longitudinal and transverse reinforcement bars, creates a firm and robust geocomposite for use in reinforced foundation layers.
This combination provides reinforcement, filtration, separation and drainage in a single product.
The geogrid-nonwoven geotextile geocomposite is used primarily on soft soils with low bearing capacity, such as unbound, dynamically loaded layers that require filtration and separation support. Typical applications include base and sub-base reinforcement for temporary and permanent roads, railways, storage yards, container terminals, temporary working platforms, airport run- ways, sludge lagoons and tailings ponds.
