Composite geogrid
Description:
Composite geogrids are a multifunctional geogrid designed to reinforce weak subgrades. Such a separation layer is often recommended in base course applications for subsoils with a CBR of less than 3% or in applications where fines or clay should be prevented from moving into the reinforced aggregate above. The biaxial geogrid provides soil reinforcement and the non woven geotextile provides separation and filtration. The high elongation capacity of monofilament nonwoven geotextiles ensures that the inter-locking ability of the composite geogrid with the fill material is not reduced and stress is transferred to the geogrid.
Composite geogrids are manufactured by heat bonding a polypropylene biaxial geogrid to a needle punched nonwoven geotextile.
They combine stabilisation of problematic soils with the additional functions of long term separation and filtration. Composite geogrids are used extensively for road and railway construction, landfills, airports and hydraulic engineering and also to provide crack control and pavement reinforcement of roads.
The benefits of installing the geosynthetic interlayer between the old pavement and new overlay include:
- Waterproofing the pavement
- Delaying the appearance of reflective cracks
- Lengthening the useful life of the overlay
- Added resistance to fatigue cracking
- Saving thickness
The composite sandwich layer, reinforced by the biaxial geogrid delivers a more efficient way to transfer load onto underlying layers.
Advantages
- Reduced aggregate thickness by combining reinforcement, filtration, separation and drainage
- Geotextile is firmly bonded to the biaxial geogrid
- Very high strength at low strains
- A strong mechanical interlock with the aggregate
- Nonwoven geotextile filters and separates the soil
- High resistance to installation damage
- High resistance to biological and chemical degradation
- Quick and easy to install
- ISO 9001 certified
Applications
- Soil reinforcement
- Subgrade stabilisation
- Slope stabilisation
- Crane and rig platforms
- Asphalt reinforcement
