Our products are applied in these fields

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

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

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

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

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.
