SOIL STABILIZATION retaining walls OVERVIEW

GEOWEB® RETAINING WALLS Retaining walls built with the GEOWEB® system are an economical, green alternative to MSE wall systems—creating a naturally-vegetated living structure while meeting all structural design requirements. GEOWEB® walls are also highly adaptable; they provide exceptional performance in soft soil environments and seismic zones, tolerate reasonable differential settlement better than rigid wall systems, can be constructed as gravity structures in areas with space constraints, and are made from environmental degradation-resistant HDPE. Flexible Design Solution The inherent...

NATURAL AESTHETICS & SUSTAINABLE VEGETATION GEOWEB® walls feature horizontal terraces with exposed outer fascia cells that create a natural environment for select vegetation and plantings. Indigenous vegetation or specified plantings may be incorporated for aesthetic appeal and sustainability. Aggregate or concrete fill provides hard-armor protection where vegetation is not desired. PERFORMANCE IN SOFT SOIL ENVIRONMENTS Flexible and light weight GEOWEB® walls adapt to a wide range of design criteria and construction requirements—meeting site challenges even in soft soil environments....

DESIGN OPTION Steepened Slopes GEOWEB® walls may be designed as steepened slopes when simple fascia protection is required over a structurally-stable soil embankment. The tiered wall structure is designed without the need for additional earth reinforcement. Reinforced Walls GEOWEB® reinforced retaining walls are designed when geogrid or other materials (geotextile or soil nails) are included for earth reinforcement. The reinforced wall system creates a fully-confined wall facing that is united with the backfill using the selected tie-back system at defined design intervals—typical of MSE...

Gravity Walls GEOWEB® gravity retaining walls are effective when space constraints prevent the use of earth reinforcement materials. The system is constructed as a layered gravity wall that resists lateral pressures and maintains structural integrity even when subgrade deformations occur. Multi-Layered Channels GEOWEB® channel side slopes with vegetative infill offer a natural appearance, stability and protection to channels exposed to erosive conditions ranging from low-tomedium flows--intermittent or continuous. GEOWEB® multi-layered channels tolerate differential settlement without loss...

GEOWEB® PERFORMANCE COMPARISONS TO MSE WALLS GEOWEB® retaining walls offer performance benefits compared to MSE block wall systems: • Vegetated fascia offers natural green aesthetics. • Open-celled front fascia infiltrates stormwater. • Flexible wall structure performs well in soft soil environments & seismic zones. • Gravity walls require no reinforcement. • Reinforced walls offer a 2X deeper facia-resistant to movement. • Installs 25-30% faster, with fewer injuries. • Redundant sections allow cutting to form around obstructions. • HDPE material is resistant to environmental degradation.

The complete GEOWEB® retaining wall system includes some or all of the following: • GEOWEB® sections • Cell infill and backfill materials • Geocomposite drainage materials • Geogrids, geotextile or other reinforcement • Subdrain Natural Colored Facing GEOWEB® wall sections are available with green, tan, or black fascia colors to blend with natural environments. The polyethylene material is ultraviolet-light stabilized to resist color fading, and increase system durability and quality performance to meet typical engineering requirements. The wall material is also extremely weather-resistant;...
