Non Woven Geotextile Separation Layer for Tunnel Project in Namibia

Non Woven Geotextile Separation Layer for Tunnel Project in Namibia

Non woven geotextile separation layer is the the permeable and durable geosynthetic layer widely used to filter, separate, reinforce, protect, retain or drain soil for civil construction applications. BPM non woven geotextile is constructed from the original continuous polyester filaments in any direction and is formed by needle-punching and thermal bonding processes during the manufacturing process to form a sturdy fabric that retains dimensional stability and resist the damage caused by building stress. BPM filament non woven geotextile separation layer is available in varying strengths and thicknesses to ensure appropriate material selection for your requirements. Custom roll size and thickness are also available.

Non woven geotextile fabric is a drainage mat material that is widely used in tunnels. The geotextile separation layer mainly serves as a cushioning protection for the waterproof board and a certain drainage effect. The geotextile separation layer is fixed to the surface of the tunnel by the dragon, and then the lining is placed on the geotextile and welded to the keel. The geotextile separation layer can increase stability and prevent freezing damage at low temperatures, as well as isolation, filtration and reinforcement.

The Four Main Functions of Geotextile Separation Layer in Tunnel Drainage Application

(1) Protect the Waterproof Board

After the hole is dug, the surface of the sprayed mortar will inevitably have many burrs, and even some exposed sharp stones. After the non woven geotextile fabric is laid on the wall, the waterproof board can be protected from sharp stones and burrs. , leakage occurred.

(2) Drainage

The non woven geotextile is used between the wall of the cave and the waterproof board to serve as a drainage. The water in the mountain will seep out on the wall of the cave and will flow along the geotextile, that is, along the inner surface of the waterproof board.

(3)Strengthen

The non woven geotextile separation layer is located between the cement sprayed layer and the waterproof board. In addition to protecting the waterproof board from being pierced by sharp pointed stones, it also strengthens the mechanical properties of the cement sprayed layer and improves the overall adhesion between the cement layer and the wall to prevent the falling and collapse of cement.

(4)Filteration

The water in the mountain often encloses a lot of impurities such as dirt, stones, grass and leaves. If there is no filtering of the geotextile separation layer, the drainage pipe will be blocked quickly, resulting in poor drainage.

HDPE Pond Liners for Large Ponds in Indonesia

HDPE Pond Liners for Large Ponds in Indonesia

HDPE pond liners for fish ponds are the commonly used Anti-seepage single-layer high density geomembrane liner. The HDPE pond liners for fish ponds has smooth surface that can effectively prevent fish from escaping during the rainy season, especially like lobster, crab, fish. Laying a layer with a thickness of 0.5 mm of HDPE pond liners for fish ponds or more (different thicknesses can be used according to specific design and engineering conditions) as an anti-seepage protection layer, you should accurately measure the relevant dimensions according to the shape of the fish pond, and then cut and stitch according to the actual situation Impervious membrane, the overlap width of the seam between the membrane and the membrane is generally not less than 15 cm. After the impermeable HDPE pond liners for fish ponds are laid, walking on the surface of the membrane and moving tools should be minimized.

BPM customer from Indonesia has 6 fish ponds and wanted to purchase   HDPE geomembrane pond liner with 0.5mm thickness.  BPM customer chose the ASTM standard geomembrane pond liner product. Because HDPE pond liners for fish ponds have many advantages：

1. Water storage. Due to its extremely low permeability coefficient, HDPE geomembrane pond liner has good water storage performance, which greatly prevent water in the fish pond from penetrating into the soil, and monitors the water level effectively, and saves related water conservation costs at the same time.

2. Water quality stability. The use of HDPE geomembrane pond liner can better maintain the balance of water quality, reduce changes in water conditions, and reduce the cost and time of water quality control.

3. Oxygen content. The use of HDPE geomembrane pond liner can reduce the loss of oxygen caused by infiltration into the soil, facilitate the monitoring of the oxygen content in the water, and reduce the cost of supplemental oxygen in the fishpond.

4.Reduce maintenance costs. The use of HDPE geomembrane pond liner can inhibit the growth of algae in water and is easy to clean.

In addition, we gave suggestions on how to lay HDPE pond liners for fish ponds. And we recommended geomembrane pond liner welding guide. BPM customer was very satisfied.

Geotextile Separation Fabric for Pavement Restoration Project in Philippine

The main functions of nonwoven geotextile separation fabric are filtration and separation, the most common used nonwoven geotextile separation fabric needle punched geotextile which is made from staple fibers or continuous filaments bonded by mechanically entangling the fibers with barbed needles. It looks and feels like felt. Although non woven geotextile has a lower tensile strength than the woven type, it still offers great strength, durability and excellent drainage properties. This type of geotextile separation fabric is easier to cut, has a high water permeability rate and does not lose strength over time, in the same way as the woven fabric does, when used below ground.  The nonwoven geotextile separation fabric is the ideal geotechnical product for road or pavement restoration project.

A considerable part of the existing cement concrete pavement is close to or has exceeded the design life due to the rapid increase in traffic volume, the increasing overload of automobiles and the design and construction reasons, the road damage is becoming more and more serious, which affects the use function of the road. As a typical modification measure, the asphalt concrete surface layer is added on the old cement concrete pavement, which is generally adopted by the old road reconstruction projects in various countries around the world. However, the added asphalt cracks often appear in the paved asphalt concrete, which will greatly affect the service life of the overlay. Recent studies have shown that the use of geotextile separation fabric is an effective and economical method to slow the reflection cracking of asphalt overlays.

BPM Phillipine client is a Manila construction contractor that undertook the renovation of a cement concrete pavement project that has been in use for more than a decade. In order to solve the problem of road surface failure, faulty platform and bottom plate void, and thoroughly improve the quality of road conditions, the engineering transformation plan of asphalt concrete surface layer was adopted, and the application of geotextile separation fabric was researched and explored. The overlaying scheme is designed to take modified asphalt concrete and special 500gsm needle punched non woven geotextile, which can achieve the effect of road surface reinforcement to increases the service life, and can reduce the engineering difficulty and reduces the engineering cost at the same time.

Specifications of Geotextile Separation Fabric for Pavement Restoration Project in Philippine

• The geotextile separation fabric can reduce the bonding force between the overlay and the old pavement layer.
• Because the geotextile has high strength and large extensibility, the geotextile separation layer can play the role of stress absorption interlayer.
• Anti-seepage effect.
• The nonwoven geotextile can reduce the tensile stress under load.
