Soil Separation & Filtration

Geotechnical, environmental and civil engineering projects typically involve an assessment of soil characteristics. Most often, synthetic products are used to help make soils more suitable for construction. This includes products that provide soil separation and filtration functions. Geotextiles are the most effective product solution for soil separation and filtration. They act as a separation layer between the sub-base soil and over topping aggregate to prevent intermixing of the two. Preventing this intermixing helps ensure structural integrity of construction projects while avoiding aggregate loss. Geotextiles can also minimize the risk of soil particles migrating into the sub-base from surface water by acting as filter. This soil filtration helps also helps preserve structural integrity.

The type of construction projects requiring soil separation and filtration is vast, however common projects where geotextiles are typically used, include:

  • Road building

  • Railway construction

  • Earth dam construction

  • Retaining wall construction

  • Drainage trenches and ditches

  • Landfill lining systems

  • Wastewater lagoon lining systems

  • Embankment and channel erosion control systems


Non Woven Geotextiles

Our non woven Geotextiles provide the containment and erosion control industries with the highest quality geotextiles available. These needle-punched geotextiles are made of 100% polypropylene staple fibers or 100% Polyester Long fimament, which are formed into a random network for dimensional stability. They resist ultraviolet deterioration, rotting, biological degradation, naturally encountered basics and acids.

Non woven geotextiles are used in many applications such as drainage, filtration, separation. They function by restricting soil particles but allowing liquid and gases to easily pass through them and are used to improve the performance of environmental and civil construction projects.
