Advantages of Geogrid:
- Fast construction and uniform concrete placement during pipe protection
- Strong bedding
- Low construction cost
- Control and drainage of surface water
- Easy cathodic protection of pipes
- Concrete reinforcement
- Fast and easy installation
- Less expensive than similar materials, such as rebar
- Full protection against aqueous corrosive agents
- Improvement in train loading capacity
- Increase in train speed
- Slope stabilization
Important points about geogrids
- High walls
Geogrids usually occupy 70% of the height of a wall.
- Ramps and double-slopes
Geogrids usually occupy the full width of an earthwork.
- Seismic design
The distance between geogrids is considered in the design. This distance is longer in areas with low seismicity.
- Slope stabilization
The distance between geogrids varies depending on the slope. For instance, the distance between rows of geogrids is 8 inches in a 1:8 slope whereas it may be as low as 1 inch in walls and vertical slopes.
Geogrids have an operating temperature of -50°C to 100°C and can be used in any climate.
Applications of geogrids
- Protection of petroleum, natural gas, and water pipes
- Erosion prevention in slopes
- Prevention of rockfall
- Manual road construction in sloughs
- Construction of braces, barrages, and earthworks
- Drainage and lining
- Soil reinforcement
- Plaster and cement wall reinforcement
- Covering of floors and concrete parts
- Water canals within tunnels
- Bedding of roads and paths
- Reinforcement of railway and runway bedding
- Asphalt reinforcement
- Stonewall stabilization
