FIBERTEX GEOTEXTILES

Fibertex Geotextiles are needlepunched nonwoven fabrics made from polypropylene mosty commonly used for layer separation, filtration, drainage, membrane protection and soil reinforcement in various construction setting, particularly civil works projects.

Fibertex's drylaid needlepunch technology is based on a three-step process. Firstly, polypropylene resin is extruded into fibers. Secondly, the fibers are carded and needlepunched. Finally, thermal treatment is added onto the geotextile. Weights range from 100 g/m2 up to 1200 g/m2.

APPLICATIONS OF FIBERTEX GEOTEXTILES

SEPARATION
The durability and mechanical properties of Fibertex Geotextiles make them ideal for separating layers in construction works. A strong and flexible Fibertex Geotextile is placed between the different layers in the construction preventing migration and mingling of materials, yet allowing free movement of water. This increases the bearing capacity and provides long-term stability to the foundation layers.

FILTRATION
The pore structure of Fibertex Geotextiles is designed to retain particles while allowing free movement of water, making it possible to separate two layers during intense hydraulic activity. Migration of layers, which would reduce the load-bearing capacity of the system, is thereby avoided and at the same time water flow is maintained with minimum pressure loss.

DRAINAGE
The hydraulic properties of Fibertex Geotextiles is designed to drain excess water off the construction - not by passing through the fabric - but by flowing in the plane of the fabric away from the construction. The use of a drainage geotextile ensures an ongoing drainage of fluids with minimum pressure loss.

PROTECTION
The excellent static puncture resistance of Fibertex Geotextiles makes them ideal for protecting waterproof membranes and other sealing materials from puncture when fill material and/or loads are applied. When placed between sealing material and other layers, the geotextile withstands and distributes any local pressure from the layer above, ensuring that the protected material is not stressed to failure.

REINFORCEMENT
The mechanical properties of Fibertex Geotextiles, Fibertex Fiberforce (geotextile strengthened with a woven structure), Fibertex HS Woven and Fibertex Geogrid (100% polyester grid), make them ideal for reinforcing slopes and other soil structures. Reinforcing with the appropriate Fibertex product prevents vertical soil walls and steep slopes from collapsing.

STRESS RELIEVING
Fibertex offers a flexible pre-compressed non-woven geotextile designed especially for stress relieving. The stress relieving paving fabric is ideal in both new road constructions and in road maintenance, as it absorbs differential movements in the road layers, preventing reflective cracking. The bitumen-saturated paving fabric also forms a waterproof interlayer, protecting the subsoil from water intrusion and thereby loss of bearing capacity.
