Functions

Separation

The durability and mechanical properties of B. J. Geotextiles make them ideal for separating layers in construction works. A strong and flexible B. J. 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 of the foundation layers.

Filtration

The pore structure of B. J. Geotextiles is designed to retain particles while allowing free movement of water, making it possible to separate two layers during intense of 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 B.J. 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 B.J. 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

Together with woven and geogrid, the mechanical and hydraulic properties of B. J. Geotextiles make the product ideal for reinforcing slopes and other earthworks. Reinforcement which incorporates the correct type of B. J. Geotextile will prevent the collapse of vertical earthworks and steep slopes.

Stress relieving

B. J. Geotextile offers a flexible pre-compressed nonwoven 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

Applications

Permanent Roads

By separating the different layers of materials, B.J. geotextiles stabilize road constructions that are designed to resist dynamic and static stresses.

Temporary Roads

B.J. Geotextiles placed below the top gravel layer increase the bearing capacity of the road to with- stand continuous heavy traffic loads. No cars, tractors or other vehicles will become stuck in the gravel.

Parking Areas

Areas subject to considerable static loads require a stable bearing course. B.J. Geotextiles provide this by separating the different layers of materials, which is essential to maintain the bearing capacity.

Road Widening

B.J. Geotextiles ensure separation and stability between subsoil and added road building materials.

Asphalt Maintenance

Bitumen-saturated prevents surface water from penetrating the bearing course, preventing washing out of fines and reducing the occurrence of fissures and cracks considerably.

Airports

In constructions with heavy demands on the surface, B.J. Geotextiles stabilize the foundations enabling them to withstand dynamic loads.

Railways

The rapidly increasing speed and weight of trains place heavy demands on the bearing course. B.J. Geotextiles stabilize the foundation, enabling it to withstand dynamic loads.

Construction works

Foundations

When placed under foundations, B.J. Geotextiles replace the blinding layer. It is simple, effective and economical.

Concrete Floors

Below concrete floors, the permeable B.J. Geotextile protects the drainage layer from contamination from the concrete and the subsoil

Impact Sound Suppression

In apartment buildings, B.J. Geotextiles are used for sound suppression purposes

Roofs

B.J. Geotextiles are used as sliding layer, mechanical protection of roof membranes and as filter protection of any drainage layers

Roof Gardens

B.J. Geotextiles are used as separation layer, mechanical protection of roof membranes and as filter protection of any drainage layer

Ground systems

Pipes and Trenches

Placing a B.J. Geotextile on the bottom of the trench increases the bearing capacity considerably

Storage Areas

Using B.J. Geotextiles prevents mingling or loss of fines in the bearing courses as well as clogging of the drainage layer

Sport Grounds

Grass fields, cinders and gravel courts/ grounds are stabilized with B.J. Geotextiles due to the effective drainage, ensuring an even surface.

Slopes

With B.J. Geotextiles under the top layer, the slope will withstand subsoil water, rainwater and water from melted snow which would, otherwise, wash out the fines

Drainage/Filtration

Drainage Pipes

With permeable B.J. Geotextiles wrapped around the pipes, an effective and long lasting drainage system is ensured, without any risk of clogging.

Drainage Trenches

B.J. Geotextiles protect the drain system by preventing mingling of fines.

Surface Drains

Surface drains are likely to become silted up from the surrounding soil. B.J. Geotextiles keep the fines separated from the drainage layer ensuring the effectiveness of the drain system.

Building Drains

In the construction of foundations and basement walls, B.J. Geotextiles ensure a clean and effective circumferential drain, which e.g. prevents damage caused by dampness

hydraulic works

Coastal Protection

B.J. Geotextiles protect the coast line as their flexibility and permeability ensure withstanding of the impact of waves and currents, preventing erosion and washing out of fines

Dams

Artificial dams and embankments need to be fortified with strong materials to resist the forces of nature. B.J. Geotextiles stabilize and prevent washing out of fines

Harbor Constructions

B.J. Geotextiles placed behind the retaining wall keep the drainage layer clean which relieves the hydraulic pressure on the wall. When placed in front of the retaining wall, B.J. Geotextiles prevent washing out of the sea bed.

River Banks and Canals

B.J. Geotextiles protect river banks and canals in an effective and environmentally friendly way

Artificial Lakes

The waterproof membrane is protected against perforation with B. J. Geotextiles

Water Reservoirs

B.J. Geotextiles protect the water- proof membrane against perforation.

Waste disposal

Waste Disposal (Top Layers)

In supervised waste disposal sites, B.J. Geotextiles on both sides of the membranes protect them from perforation. Furthermore, B.J. Geotextiles are used as filter protection of the drainage layers.

Waste Disposal (Bottom Layers)

As described above, B.J. Geotextiles on both sides of membranes protect them from perforation. B.J. Geotextiles also help to detect leaks.

Water Purification Systems

B.J. Geotextiles on both sides of the waterproof membrane protect the system against perforation.

Coastal protection from B. J. Geo-textile:

B. J. Geotextiles are used in protection structures in coastal areas, rivers and harbors, for erosion control, dune revetments and slope protection, as well as in flood emergencies. Our geo-synthetic solutions also encompass products improving durability of concrete structures like coastal bridges, tunnels and marine structures.
