Geogrids

Geogrids are polymeric products formed by joining intersecting ribs. They have large open spaces also known as “apertures”. The directions of the ribs are referred to as machine direction (MD), orientated in the direction of the manufacturing process or cross machine direction (CD) perpendicular to the machine direction ribs. Geogrids are mainly made from polymeric materials, typically polypropylene (PP), high density polyethylene (HDPE) and polyester (PET).

• Geogrids promote soil stabilization.
• Provide higher load bearing capacity.
• Geogrids are flexible in nature and are well known for their versatility.
• Geogrids have high durability which reduces maintenance cost.
• Geogrids are highly resistant to environmental influences.
• Easy to install which results in faster construction.

There are several major markets for geogrids. These are base reinforcement, earth retaining wall construction including veneer stabilization, the segmental retaining wall market, embankment reinforcement and pile cap platforms. Biaxial geogrids are primarily used in base reinforcement applications, while the uniaxial geogrids are often used in the other markets.

The base reinforcement market is just what the name implies. These are applications where engineers are trying to improve the performance of a gravel base over poor soils, trying to minimize the amount of gravel in the base course design, or increasing the life of the surface cover, concrete or asphalt. Geogrids are used under parking lots, airport runways, gravel construction roads, highways, dam levees and railroad tracks.
