Gabions retaining walls are used for erosion control and scour protection support in slopes, shorelines, rivers and retention walls. Although they provide good earth stabilization if constructed properly, gabion installation process is complicated. The construction of Gabion basket retaining walls require a large amount of specific rock size, heavy equipment and stable platforms and their construction is time consuming. In terms of landscape visual aesthetics gabion designs are limited by their steep rock face and basket patterns.
PRS-Neoweb™ on the other hand provides the same or better erosion contronl and slope bank protection, but offers a much larger range of design and layout options. PRS-Neoweb is also a green solution, as the geocells serve as an ideal growth environment for the reestablishment of natural vegetation and landscape, much more than green gabion systems.
|TOPIC||PRS-Neoweb GEOCELLS||GABION SYSTEM|
|Deformation||High stability due to small cell size||Easily deformable due to void space between stones|
|Installation||Quick and easy with work crews trained on site||Requires skilled placement and cranes to hoist in place|
|Infill||Uses ungraded native or marginal soils and infill||Requires specific quarried aggregate size and shapes|
|Versatility||Wide range of slope and wall design options and infill materials||Limited to steep vertical stone terraced|
|Base and Excavation||Very small footprint even in compressible soils||Requires excavation and base width at least 50% of total height|
|Landscape Aesthetics||Enhances plant growth and landscape restoration||Monolithic rock face only|
|Maintenance||Strong, stiff and durable cells require little maintenance||Regular maintenance of wire required|
|Sustainability||Uses local, marginal or recycled materials for infill||Requires specific quarry stone and hauling|
