For instance, based on the characteristics of the intended backfill to be used, load factors, required service life and other considerations, engineers select from our four main categories of geosynthetic soil reinforcing strips:
Coated polyester (PET) strips without high-adherence edges, best for low pH backfill
> HA GeoStrap®
Coated polyester (PET) strips with high-adherence edges, best for low pH backfill
Coated polyvinyl alcohol (PVA) strips without high-adherence edges, best for high pH backfill
> HA EcoStrap™
Coated polyvinyl alcohol (PVA) strips with high-adherence edges, best for high pH backfill
From the four reinforcing strip categories listed above, engineers optimize the design even further by selecting among various intermediate grades in terms of strip strength (25kN to 100kN), and density (5mm to 9mm).
The welded wire facing elements are also optimized in terms of variable bar diameters and grid spacings. Engineers can select between galvanized facings and hardware or ungalvanized steel based on the required service life and environmental conditions.
Applications for GeoTrel™
Geotrel™ is used to build both permanent and temporary civil structures. Some examples of common applications:
> Natural risk mitigation
Geotrel™ barriers are well known for constructing rock fall and avalanche protection. These are reliable structures that permit both high energy levels and multiple impacts to be controlled.
> Industrial environment
Used widely for building crusher pocket walls, haul roads and bridges, industrial platforms, and tunnel collars walls.
> Landscaping with steep slopes and terraces
Geotrel™ offers owners and developers an attractive alternative to concrete for building permanent residential or urban retaining walls and vegetated slope applications.
> Temporary retaining walls
Nearly all applications that involve temporary earth retention and embankment stabilization can be carried out with GeoTrel™ solutions. In case of phased construction, the temporary Geotrel™ structure can remain in place and be buried after functioning as a stable retaining wall during the first phase of construction.
Builders have found Geotrel™ to be an excellent solution for building temporary stabilized reinforced soil embankments needed to induce accelerated settlements of foundations.
