Geogrid

Description

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
