Biaxial Geogrid for Base and Soil Reinforcement

Biaxial Geogrid with Excellent Reinforced Performance

Biaxial geogrid is a type of geogrids. It is made from high polymer. Biaxial geogrid has high strength in both longitudinal and transverse direction. It is made through the process of extruding, sheet forming, punching and stretching.

You can find more information on our web, so please take a look.

Biaxial geogrid has good bearing capacity. It can enhance soil structure and prevent soil erosion. This product is often used to prevent the road from reflective and fatigue cracking. Biaxial geogrid can effectively improve the long term durability of subgrade and greatly reduces road maintenance costs.

Biaxial geogrid has good resistance to long term degradation. It is suitable for various applications, such as embankment reinforcement, wall reinforcement, soil stabilization, slope protection and other permanent load bearing foundation reinforcement.

The stable two-directional structure can ensure the small deformation of biaxial geogrid.

The width, length and apertures of biaxial geogrid can be customized according to your needs.

Biaxial geogrid can reinforce various materials, such as gravel, stones, cement, concrete and asphalt.

Biaxial geogrid is widely applied in the subgrade reinforcement of railroad.

Biaxial and Uniaxial Geogrids

Biaxial and Uniaxial Geogrids

Biaxial geogrids and uniaxial geogrids are the most common types of geogrids. A geogrid is defined as a geosynthetic material consisting of connected parallel sets of tensile ribs with apertures of sufficient size to allow strike-through of the surrounding soil, stone, or other geotechnical material (Koerner ). More simply described as plastic lattice structures with different technical properties and functions.

A biaxial geogrid is a bi-directional structure with two-way stretch which provides the same mechanical properties in two directions, both longitudinal and transverse. A uniaxial geogrid is a unidirectional structure with one-way stretch that provides stabilization in one direction only, mainly longitudinal.

Each is used in specific civil engineering applications depending on the desired reinforcement and stabilization outcomes. Biaxial geogrids allow for wider load distribution making them ideal for construction of roads, working platforms, or preparation of site subgrades where base stabilization is needed in two directions; while uniaxial geogrids are best used in construction of structures with a vertical component like earth retaining walls and steep soil slopes. This geogrid provides reinforcement in one direction.

Titan offers both biaxial and uniaxial geogrids suited to different applications and civil engineering designs.
