Polyester Filament Woven Geogrid Road Reinforcement Construction and Mining Roof

Polyester geogrid for soil reinforcement-Flexgrid

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.

Features

• Easy to handle and install

• Wide rolls for reduced laps and wastage

• Independent testing of properties to verify performance

• Suitable for a wide range of soil types

• High resistance to biological and chemical effects

Supply

Supplied in the following standard grades (other grades available)

PET Woven Geo-grid Designed For Underground Mining

(Mining Grid)

Product Description

Mining grid is manufactured from high-tenacity polyester then coated with conducting electrostatic, with the high fire retardant acid and alkali resistance to achieve flame-resistant, antistatic properties. It covers wide range of tensile strengths, from 20 kN/m to 1200kN/m. Standard roll size is 5m x 100m, but shorter, narrower rolls can be supplied upon request.

It can be widely used in mining engineering such as the intermediate ceiling, long walls and side protection grid and other fireproof structures in mining projects. It can also be used in subway and tunnel, etc fixing projects.

Mining Grid Advantage

•Lightweight, flexible, simple & quick to install, and reduce overall project costs
