SOIL STABILIZATION slope & shoreline protection OVERVIEW

The Presto GEOWEB® slope and shoreline protection system is an effective and economical solution to challenging slope-surface stability problems. GEOWEB® slope protection systems meet a wide range of performance and aesthetic requirements with select infill. Typical Applications • Cut or fill embankment slopes • Containment dikes and levees • Shoreline revetments • Geomembrane protection • Landfill linings & covers • Stormwater basins • Wastewater lagoons • Dam faces and spillways • Abutment protection THE GEOWEB® SYSTEM GEOWEB® System Benefits • The 3D cellular confinement...

Vegetated Slopes SUSTAINABLE VEGETATION The GEOWEB® system’s 3D cellular network stabilizes topsoil for sustainable vegetation on slopes up to 45° and higher. The system prevents severe erosion caused by surface runoff and sheet flow, and offers slope-surface stability not possible with 2D planar systems. Infill confined in the GEOWEB® 3D system creates a structural surface layer that resists sliding, where each isolated cell creates an eco-zone protected from erosive forces. GEOWEB® vegetated slopes are a green solution ideal for Low Impact Development (LID) and Green Infrastructure (GI)...

□ Aggregate Slopes PERMEABLE, HARD-ARMORED SLOPE COVER The GEOWEB® system's 3D cellular structure significantly improves the stability and erosion-resistance of granular materials, making them far more stable than when unconfined. Confinement of aggregate also allows a significant reduction in size and less expensive materials to be used for a low-maintenance slope cover. Aggregate infill reduces environmental impacts by allowing water infiltration on the slope face, reducing sheet flow runoff. A wide range of slope angles can be accommodated by selecting the appropriate cell size and cell...

Concrete Slopes FLEXIBLE, HARD-ARMORED PROTECTION GEOWEB® slopes with concrete infill provide economical, hardarmored protection of slopes exposed to severe hydraulic or mechanical stresses. The quality, surface finish and thickness of the concrete can be selected to meet specific design needs. Concrete-filled GEOWEB® sections are flexible, pouredin-place articulating mats that are more economical than articulated concrete block systems (ACBs) without requiring specialized equipment to install. BENEFITS OF GEOWEB® 3D CONFINEMENT: • Formless system reduces construction costs by eliminating...

D Geomembrane Protection FULLY-INTEGRATED SUSPENDED SLOPE COVER SYSTEM The GEOWEB® system may be designed as a protective cover over impervious geomembranes to prevent damage and degradation. GEOWEB® liner protection is a 'complete solution' including integral tendons and ATRA® tendon load transfer clips to create a suspended support system with selected infill. By confining infill in the GEOWEB® system, slopes can be designed steeper while still maintaining strength and integrity of the liner. Ideal Applications: Stormwater detention and retention ponds, wastewater containment,...

DESIGN CRITERIA Slope protection details are influenced by the embankment angle (H:V), length, and infill. Presto’s free project evaluation service can help determine the suitable cell size, cell depth and structural components for your project. KEY COMPONENTS The complete GEOWEB® slope protection system may include some or all of the following: TYPICAL COMPONENTS OPTIONAL COMPONENTS • GEOWEB® sections • Polymeric tendons • ATRA® Key connection device • ATRA® Tendon Clips • Cell infill materials • Geotextile separation layer • ATRA Anchors & Speed Stakes INTEGRAL SYSTEM ACCESSORIES The...
