MacGrid Maccaferri

MacGrid® are deformed or\non deformed grid like polymeric material formed by intersecting ribs joined at the junctions

The fundamental working mechanism is by friction. In the extruded grids a confining effect over the soil particles that lodge in the openings of the grid itself can be taken into account.

We have three types of Geogrids; extruded, woven and bonded.

  • Extruded Geogrids are flat structures in polymer (usually high density polyethylene or polypropylene) that are extruded and then pulled: this may be done in one direction (mono-oriented geogrids), or in the two main directions (bi-oriented geogrids). They are used in soil and road paving reinforcement.
  • Bonded Geogrids are flat structures, where two or more series of strip elements made of polyester coated with polyethylene, are linked at regular intervals by means of bonding.
  • Woven Geogrids are flat structures in the shape of a net made of high module synthetic fibres, that may also be coated with a further protection layer,  using synthetic material (usually PVC or other polymer).

MacGrid® AR

MacGrid® AR are planar geogrid structures used for the reinforcement of asphalt roads. The geogrids are made from glass fibre or polyester woven together in a grid configuration, which is then coated.

MacGrid® EG

MacGrid® EG are high modulus high density polyethylene (HDPE) grids, produced by an punched and extruded process and characterized by a tensile resistance in both longitudinal and transverse directions.

MacGrid® T

MacGrid® T is a composite for soil reinforcement, made from a woven geogrid of high tenacity polyester multifilament yarns protected by a polymeric coating.

MacGrid® WG

MacGrid® WG geogrids are used for most soil reinforcement applications such as reinforced soil slopes and when soil consolidation and support is required.
