FREQUENTLY ASKED QUESTIONS

What are the main types of geotextiles?

Woven Geotextiles: Made by weaving fibers together (like a mesh), offering high strength and load distribution.
Non-Woven Geotextiles: Made by bonding fibers mechanically/thermally/chemically, providing better filtration and drainage.

What are the applications of geogrids?

Road and railway base stabilization
Retaining walls and steep slopes
Foundation reinforcement

Erosion control
Landfill systems
Embankments over soft soils

What is a geotextile?

Geotextile is a permeable synthetic fabric made from polyester or polypropylene, used in civil engineering and construction for separation, filtration, drainage, reinforcement, and erosion control.

What is a geogrid?

Geogrid is a geosynthetic material made from polymers (typically polyester, polyethylene or polypropylene) with an open grid-like structure. It's used primarily for soil reinforcement and stabilization in civil engineering applications.

What are the main types of geogrids?

Uniaxial geogrids - Strong in one primary direction, used for wall and slope reinforcement
Biaxial geogrids - Equally strong in two perpendicular directions, used for base reinforcement
Triaxial geogrids - Multi-directional strength with triangular apertures, used for base stabilization

Can geotextiles be used with geogrids?

Yes! They are often combined.
Geotextile for filtration/separation.Geogrid for reinforcement.

Our products are applied in these fields

Retaining Walls

Retaining Walls


Geogrids are polymer-based geosynthetic materials used to reinforce soil behind retaining walls, installed in horizontal layers that extend into the backfill. By stabilizing the soil mass, they enhance the structural integrity and load-bearing capacity of the wall system.

Soil Reinforcement

Soil Reinforcement


Geogrids and Geotextiles enhance soil stability by adding tensile reinforcement, improving strength and deformation resistance. These materials allow engineers to construct embankments on soft ground and design steeper earth slopes safely. Their reinforcing function provides crucial structural support where traditional soil alone would fail.

Drainage Systems

Drainage Systems


Geotextiles are used to prevent road base materials from penetrating into soft underlying soft subgrade, thus maintaining design thickness and roadway integrity. Geotextile separators also prevent fine-grained subgrade soils from being pumped into permeable, granular road bases

Erosion control

Erosion control


Geosynthetics provide immediate sediment stabilization while creating a supportive matrix for revegetation, with material selection based on site-specific hydraulic and topographical conditions. These engineered systems combine immediate erosion protection with long-term soil reinforcement, capable of withstanding high-velocity flows during both initial installation and subsequent vegetation establishment phases.

Filtration

Filtration


Geotextiles retain soil particles while allowing water flow, utilizing a 'bridging' effect where larger particles help trap finer sediments, working best in one-directional flow. Their performance can be customized through fabric design and are often paired with drainage cores in geocomposites to prevent soil migration in drainage systems or protect riprap in waterways.
