1 What factors are related to the longevity of geotextiles?

The use of geotextile has been very popular, but the product has a certain period of use, so we need to extend its service life through some methods to make the use of geotextile more in line with our application needs.

In order to enhance the service life of geotextiles, we should try to shorten the exposed moment of the material in the daylight, cover it with rocky soil or deep water more than 30 cm thick, etc.; and add an anti-aging agent to the original material to press the effect of light, oxygen, heat and other external elements on the product. Some manufacturers will also add anti-aging agents in polypropylene, by 4 years of direct sunlight exposure, the strength is only 25% loss, if not add anti-aging agents, directly under the sun for 2 to 3 months, the strength is lost.

In addition, before the geotextile laying construction, but also the filament geotextile all and splicing parts to view, make a mark in time to repair matters, in the daily protection to prevent long periods of strong light shine, and to keep away from water, high-temperature storage environment.

2 Future geotextile market outlook trends?

Geotextiles will be more and more widely used, no doubt, environmental protection, infrastructure, geotextile market applications will not stop.

Application areas are as follows

  1. As reinforcement in the backfill of retaining walls, or for anchoring the panels of retaining walls. Construction of wrapped retaining walls or bridge abutments.
  2. Reinforcing flexible pavement, repairing cracks on roads, and preventing reflective cracks on roads.
  3. Increase the stability of the gravel slope and reinforce soil to prevent soil erosion and frost damage to the soil at low temperatures.
  4. Isolation layer between road ballast and roadbed, or isolation layer between the roadbed and soft foundation.
  5. Isolation layer between artificial fill, rock pile or material field and foundation, isolation between different permafrost layers. Reverse filtration and reinforcement effect.
  6. The filter layer of the initial upstream face of an ash storage dam or tailing dam, the filter layer of the drainage system in the backfill of a retaining wall.
  7. The filter layer is around the drainage culvert or around the gravel drainage culvert.
  8. The filter layer of water wells, pressure-reducing wells or inclined pressure pipes in water conservancy projects.
  9. The isolation layer of geotextiles between highways, airports, railroad dodges and artificial rock piles, etc. and the foundation.
  10. Vertical or horizontal drainage inside the earth dam, buried in the soil to dissipate the void water pressure.
  11. Drainage behind geomembranes in earth dams or earth embankments or in the lower part of concrete sheathing.
  12. Drainage of water seepage around the tunnel to reduce the external water pressure on the lining and the seepage around each building.
  13. Drainage of sports field foundations on artificially filled land.
  14. Highway (including temporary roads) railroads, embankments, earth and rock dams, airports, sports fields and other projects used to strengthen the weak foundation.
