Nonwoven Geotextile Fabric – Geo Sheet

B. J. Geo-textile Ltd. the leading and largest non-woven needle punched synthetic geotextile fabric or geo sheet manufacturer in Bangladesh. We are producing largest quantity of geo sheet in a day. Geotextile Fabrics are made from high strength fibre made of world class raw materials and European additives.

The government, semi-government and leading business enterprises of Bangladesh are using B. J. Geotextiles’ non-woven synthetic geotextile fabric products for River Bank protection, River training, coastal protection, separation and reinforcement.

Our geosynthetic products are used in separation, filtration and supporting the progress of the country. With world-class products ensuring high-quality delivery to geotechnical and environmental engineering domain.

Bang Jin using European latest developed nonwoven needle punch technology to manufacture its wide range of products.

Non-woven needle punch is a combination of needling and thermal bonding process of fibers. Being polypropylene, the fibre used in the production of the non-woven product range are extremely durable and exhibit excellent chemical resistance to acids and alkalis at ambient temperatures, have an exceptionally low moisture absorption such that the action of water at ambient temperature has no effect on their mechanical properties and are resistant to microorganisms & insects and will not support the growth of mildew or fungi.

The nonwoven range of the staple fiber needle punched and thermally bonded nonwoven textiles have been designed to offer optimum performance per unit weight. Their resulting mechanical robustness and excellent hydraulic properties make them the ideal choice for separation and filtration.

Product Specification:

• Weight: 120 gsm – 800 gsm
• Width: Max 5m
• Color: As per customer requirements
• Composition: Polypropylene / Polyester / Re-generated
• Technology: Non-woven Needle punched

The most effective applicable areas of this geo-textiles technology are to protect erosions. Geotextiles provide the best protection for erosion prone sedimentary soils which are deficient in stability due to insufficient cohesion. In Bangladesh river bank soils are very unstable from erosional point of view. These soils are deposited by the action of river flow and therefore, are very prone to re-transportation. Geo-textiles technology provides the most effective solutions for these types of soils. The construction procedures practiced in Bangladesh is only intended for protection of river bank surface layers from erosion.

The existing designs normally do not incorporate any measure for overall stability of the slopes due to, for example, failure as a result of seepage towards the river, under rapid down condition. B. J. Geo-textiles technology may be used in these applications in reinforcing the banks from deeper failures as well as protecting the surface layers from erosion due to flow and/or wave action.

There are at least 80 specific applications areas for geotextiles that have been developed; However, the fabric always performs at least one of five discrete functions:

• Separation – the use of a geotextile to prevent the intermix of dissimilar soil layers
• Filtration – the use of a geotextile to allow the passage of fluids (mot commonly water) while preventing the uncontrolled passage of soil particles
• Reinforcement – the use if the tensile properties of a geosynthetic material to resist stresses or contain deformation in soil structures
• Drainage – the use of a geosynthetic layer to collect and transport fluids within its own thickness
• Protection – the use of a geosynthetic material as a stress reduction layer to prevent or reduce damage to an adjacent surface or layer
• Erosion control – the use of a geosynthetic material to prevent the loss of soil particles from water erosion

In Bangladesh geotextiles are highly used for river bank protection
