Laying pavements and roads can be a long-term project that requires constant maintenance and precision to create strong roads. Soils can often be variable or weak which can affect road use long term. To help solve these problems the Biaxial Geotextile provides Omni-axial support and reinforcement to these weak or viable soils. They also provide reinforcement to capping layers, railway ballast and granular sub bases.

The Biaxial Geotextiles work by compacting granular particles over the grids, which partially penetrate and project through the apertures to create a tough, durable, and positive interlock. The interlocking mechanism creates a load dispersal effect which increases the shearing resistance in the soil, improving the compaction and allowing the sub base thickness to decrease, which in turn reduces the time and cost of construction.

A very low maintenance system the biaxial geotextile is a cost-effective solution to pavement problems and can be used on:

• Construction haul roads
• Paved and unpaved roads
• Railways and ports
• Working platforms on weak sub-soils
• Parking and paved areas
• Multi-layer applications
• Piling platforms

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.
