PP Triaxial Geogrid

Introduction:

Triaxial geogrid is manufactured from polypropylene,mainly applied in strengthening soft ground of highway,railway,slope protecting projects, airfields etc.It can increase stability and loading capacity of fundus,prolong the project life. This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation as a reinforcement material.

Features:

1. Increase the bearing capacity of the roadbed and foundation and prolong their service life.

2.     2. Prevent road surface and foundation from sinking or flawing, keep clean and beautiful ground surface.

3.     3. Convenient construction saves time and labor, reduce mounting time and decrease maintenance expense.

4.     4. Prevent culverts from flawing.

5.     5. Enhance earth slope and prevent water loss and soil erosion.

6.     6. Decrease underlayer thickness and save manufacturing cost.

7.     7. Enhance the stability of side slope turf net patch to improve greening.

8.     8. Replace wire netting used in mine as intermediate ceiling netting.

Application:

Geogrids focus almost entirely on reinforcement applications, although separation may be a function.  The following are examples of a few applications.

Slope Reinforcement- embankments over soft soils, extra-steep earthwork slopes, landfill liner systems, and industrial and contaminated land reclamation

Base Reinforcement- foundations of roadbeds, parking lots, railroad tracks beds, airports runways, permanent unpaved roads, construction haul roads

Wall Reinforcement- retaining walls, sea walls, airport noise barriers, and bridge supports

Berm Reinforcement - spillway channels for earthen dams, levees, and waste contaminated ponds, banks for earthen canals and waterways.
