Non Woven Geotech Landscape Fabric for Soil and Water Conservation in Thailand

Geotech landscape fabric, also known as geotextile fabric, is a kind of non-woven and industrial fabrics. The staple fiber needle-punched geotextile uses polyester crimped staple fiber with a denier of 6-12 denier and a length of 54-64mm as raw materials. Through the process of opening, carding, messy (short fibers intertwined), laying (standardized entanglement and fixation), needle punching and other production processes of non-woven production equipment, it is made into geotech landscape fabric.

Non Woven Geotextile Features

• The non woven geotextile utilizes the good air permeability and water permeability to allow water to pass through, thereby effectively intercepting sand and soil loss;
• Geotextile fabric has good water conductivity, it can form a drainage channel inside the soil, and drain the excess liquid and gas from the soil structure;
• Geotextile fabric can enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil;
• The geotextile fabric can effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being damaged by external forces;
• The non woven geotech landscape fabric can prevent mixing between the upper and lower layers of sand, soil and concrete;
• Due to the strain and mobility of the network structure formed by the indeterminate fibrous tissue, the holes are not easy to be blocked;
• With high water permeability, it can still maintain good water permeability under the pressure of soil and water;
• Using polypropylene or polyester and other chemical fibers as raw materials, it is acid and alkali resistant, non-corrosive, non-worm-eaten, and anti-oxidation.
• Complete specifications: width up to 6 meters. It is currently the widest product in China, with a mass per unit area: 100-600g/㎡;

 The basic requirements of non woven geotextile laying

• The joints must be intersected with the slope line; where they are balanced with the toe of the slope or where stress may exist, the interval between the joints must be greater than 1.5m.
• On the slope surface, anchor one end of the geotextile, and then put down the coiled material on the slope surface to ensure the tightness of the geotextile connection.
• All geotextile fabric must be pressed with sand bags. The sand bags will be used during the laying period and kept until the layer of material on top of the laying.

Precautions for Geotextile Installation

Geotextile fabric can only be cut with a geotextile knife (hook knife). If it is cut in the garden, special protective measures must be taken for other materials to prevent it from being caused by cutting the geotextile. Unnecessary damage; while laying the geotextile, all necessary measures must be taken to prevent crushing of the underlying material; when laying the geotextile, care must be taken not to allow stones, a large amount of dust or moisture, etc., to crush the geotextile,

Substances that may obstruct the drainage canal or overflow the net, or may bring hardship to the next connection are buried under the work cloth or geotextile in the grave; after the installation is completed, visually inspect the appearance of all the geotextiles to determine all damaged Place signs and repairs to make sure that there is no foreign material that can cause damage to the paved surface, such as broken needles and other foreign objects.
