Combigrid-Polyester Filament Stitch-Reinforced Nonwoven Geotextile Composite Pavement Reinforcement System

Polyester Filament Woven Geogrid Stitch-Reinforced Nonwoven Geocomposite for soil reinforcement

Flexgrid is a geogrid manufactured from high modulus polyester yarns to ensure the long term structural stability of reinforced soil structures. Flexgrid geogrid can accomodate extremely high loads due to low-creep, high-modulus raw materials. The product's relatively low reduction factors have been verified and certified by independent research institutes and testing laboratories.

Flexgrid geogrid with its open-meshed structure interlocks excellently with most engineering soils. Anchor lengths can therefore be short, reducing costs and reducing the extent of the earthwork operations. Flexgrid is flexible, supplied in widths up to 5.2m and is easy to handle making it well suited for reinforced soil slope and mechanically stabilised soil wall applications.

Properties

Flexgrid is a geogrid manufactured from high modulus polyester fibres that are laid in a flat orientation that enables maximum load efficiency. The fibres are polymer coated to improve the resistance of Flexgrid to installation damage and environmental effects. The high modulus polyester used in the manufacture of Flexgrid and the strict manufacturing and testing quality assurance support the use of Flexgrid in structure having a design life of up to 120 years.

Application

Flexgrid is supplied in rolls up to 5.2m in width. Flexgrid has its main strength in the longitudinal direction, it is easy to handle and install, can be folded or cut to the required length. Flexgrid can be used in a wide variety of fill types from clays to sands up to well graded aggregates having a maximum particle size of 65mm. The wide range of testing with these fill types allows Flexgrid to be used for reinforcement of soil embankments, soil slopes, landfill veneers, bridge abutments and retaining walls.
