Polymer: High Density Polyethlene: Polymers and master-batch for the production of E’GRID Geogrids have been strictly tested and selected and performance confirmed in the company's Research and Development Laboratories. Production is tested and quality controlled in strict accordance with international standards and stable properties are guaranteed..Resistance to Ultra-violet light: A high level of resistance to U-V light is given to E'GRID Products by the incorporation of not less than 2% of weathering-grade carbon black, well dispersed in the polymer matrix. These products may be used for many years in exposed conditions..Chemical and Biological Resistance: E'GRID Uni-axial Geogrids are manufactured from High Density Polyethylene which is unaffected by all chemicals, including acids, alkalis and salts, normally found in soils. Also, it is not a nutrient, therefore these products are not affected by micro-organisms in soil..Creep Performance: A good creep performance under sustained loading is essential for the use of geogrids in critical structures such as walls, abutments and steep embankments. BOSTD Geosynthetics Qingdao Ltd. maintains constant Creep testing programmes in its laboratories and works closely with National and International experts in the performance of geogrids to ensure that its products meet the strictest demands in all markets..Properties | Product | Tensile Strength(KN/m) | Tensile load(KN/M) at a strain of

Uniaxial E'Grid ProductsE'GRID Uni-Axial Geogrids are meshes with elongated apertures made from high density polyethylene (HDPE) and generally used as reinforcement of walls and slopes. Their principle characteristic is good creep performance with low strain and high strength under constant load.Areas of Application| Walls and abutment reinforcement E’GRID reinforced soil walls and abutments are composed of wall facing, and fill reinforced with E’GRID Products. They can be constructed quickly with simple technology, machinery and techniques and at low cost.They are tough and elastic composite structures of purpose designed multiple layers of E’GRID Reinforcement and fill. They can accommodate base deformation and have particularly good resistance to vibration and earthquakes E’GRID reinforcement can improve the bearing capacity and factor of safety of a structure and reduce construction cost. | |
| Reinforcement of Slopes In construction of roads and railways reduced land take convenient construction and good safety margins can be achieved by using E’GRID reinforcement. In environmentally sensitive areas steep, vegetated slopes can often be built in place of the hard-facedstructures such as brick , stone or concrete, that would be needed with conventional techniques. | | Steep Slopes E’GRID Reinforcement can be used to construct steep slopes with a surface of natural vegetation. Construction involves raising the slope with E’GRID Products layered into the fill and wrapped around the face to the required slope angle. Using this technique safe structures with permanent vegetation faces can be built to integrate spent quarries into the local environment. | | | Failed Slope ReinstatementThe material of the failed slope can be excavated and reused with E’GRID reinforcement to reinstate the failed area. This process is low cost and has minimal impact on the local environment during and after reconstruction work.Application:
Uniaxial geogrid is kind of high strength geosynthetic. It has extensive applications in dyke, tunnel, pier, highway, railway and building. |
