Channels subjected to high flows and associated shear stresses are susceptible to washout of natural soils and rock, which leads to uncontrolled water movement and further degradation. Typical riprap and concrete protection can be expensive and difficult to install. The GEOWEB® channels may be designed with a variety of infill materials to meet aesthetic requirements and resist anticipated hydraulic flows and associated stresses. The GEOWEB® Channel Protection System provides a variety of economical and flexible protection treatments for open channels and hydraulic structures. The system delivers stability and protection for channels exposed to erosive conditions ranging from low to high flows—either intermittent or continuous. The GEOWEB system—which can be filled with topsoil, aggregate, or concrete—lowers costs for stormwater control by utilizing on-site materials and eliminating the need for internal reinforcement. The GEOWEB channels can withstand high-velocity flow over long channels, and the ability to incorporate energy dissipation allows the GEOWEB system to successfully perform when applied along steep slopes. Learning Objectives: Understand the benefits of GEOWEB channel protection from accredited research and testing. Learn how the GEOWEB confinement system can accommodate typical construction issues and design problems.

In railroad applications, the GEOWEB® Ballast Stabilization System reduces the vertical pressure reaching the subgrade and provides a high-stiffness foundation. GEOWEB-stabilized ballast significantly reduces ballast movement, aggregate rotation, and rail settlement—resulting in increased ballast life and long-term performance. Learning Objectives: Understand the benefits of GEOWEB-stabilized ballast from accredited research and testing. Learn how the GEOWEB stabilization system can reduce vertical ballast pressure and ballast movement. Understand the typical applications for GEOWEB ballast stabilization. Learn how to apply GEOWEB stabilization to extend rail life and reduce maintenance.
Today’s environmental regulations are becoming increasingly stringent, resulting in the need for Low Impact Development (LID) and Green Infrastructure (GI) management on project sites. In order to limit hard surfaces such as parking lots, walkways, and emergency access lanes, new and innovative methods are required. As land access is at a premium and areas of environmental protection are expanding, builders and engineers must collaborate with regulators to incorporate LID and GI practices. One effective and cost-efficient way to decrease impervious surfaces on-site and restore the natural water cycle is through porous pavements. These pavements also reduce the size of above-ground detention ponds and minimize the need for conveyance and treatment infrastructure. Additionally, low-maintenance solutions such as stormwater diversion channels, roadside swales, and drainage ditches can be employed to prevent erosion and overflow issues. Living green walls further increase vegetation on-site, promote water filtration from higher elevations, and enhance access to valuable land. Learning Objectives: Learn what Low Impact Development and Green Infrastructure mean for residential and commercial project sites. Gain an understanding of the regulations governing these practices and how they have been met with traditional construction methods. Learn about porous pavement options and their benefits and limitations related to… Read more »
When paved and unpaved roadway surfaces are built over weak subgrades, base deterioration can lead to degradation. This causes unwanted deflections, rutting, and cracking in the surface layer. Using the GEOWEB® Soil Stabilization System reduces the vertical pressure on roadways and provides a high-stiffness foundation. This increases the load capacity of the subgrade allowing it to more effectively handle heavy and repeated vehicle leads. In the base layer under hard pavements, confinement of aggregate significantly reduces movement and settlement, increasing the life of the pavement. Unpaved roadways also benefit from a more stable surface that performs as an on-site stormwater “detention” basin, promoting infiltration at the source and reducing runoff. Learning Objectives: Understand the benefits of using the GEOWEB Soil Stabilization System to stabilize surfaces for unpaved roads using low-quality fill. Discover how 3D-confined base material reduces cross-section and provides a more stable base, especially over soft subgrade soils. Learn how the GEOWEB system reduces vertical pressure and subbase movement. Learn how to design pavement that will help meet on-site stormwater regulations and low environmental impact goals.
Presto Geosystems offers its free GEOWEB® MSE design software for gravity and reinforced wall applications. Create vegetated and non-vegetated MSE structures based on the GEOWEB® system inputs for reinforced slopes, gravity walls, and geogrid-reinforced walls. The software is based on industry-standard design methods and contains specific algorithms that capture the unique interaction between the GEOWEB® system, retained, foundation, and reinforced soil; specific factors of safety; and geogrid reinforcement, if applicable. This webinar will provide an in-depth tour of the MSE wall design software. You will learn how to navigate the software and input simple data to create a full-graphic design analysis and cross-sectional drawing. In this webinar, you will learn: About the different types of retaining wall systems possible with the GEOWEB system. How the MSE Wall Design Software functions and the supporting design theory. How the software performs an analysis with simple data input screens for both gravity and reinforced systems. About real-world applications through an overview of case studies.
Retaining wall systems are used to hold back earth and achieve grade separation between two adjacent points at different elevations. There are many types of retaining wall systems, including concrete, steel, gabions, sheet piling, and reinforced soil. The GEOWEB® Retaining Wall System, in general, belongs to the reinforced soil category. Depending on the slope angle and site conditions, retaining walls are commonly referred to as gravity walls, reinforced walls, or reinforced soil slopes. The GEOWEB Retaining Walls make it possible to stabilize soil at the face of the wall or slope with a naturally vegetated fascia. The GEOWEB system’s open-celled terraces create a natural environment for sustainable vegetation and allow stormwater infiltration. The GEOWEB walls conform well to landscape contours, are resistant to environmental degradation, and install 25-30% faster than MSE block walls. Learning Objectives: Learn about the different types of retaining wall systems that can be built with the GEOWEB system. Understand the design of the GEOWEB System for various wall and reinforcement types, applications, and site conditions. Learn about unique system features and what sets GEOWEB Retaining Walls apart from other types of walls.

When unpaved roads, drill pads, and work platforms are constructed over weak subgrades, base deterioration can lead to degradation. This degradation leads to unwanted deflections, rutting, and ultimately failure of the surface layer. The GEOWEB® Soil Stabilization System significantly reduces the vertical pressure reaching the subgrade, provides a high-stiffness foundation and reduces cross-section thickness up to 50% or more. Increasing the load capacity of the subgrade allows it to effectively handle heavy vehicle and drill rig loads while reducing maintenance cost. Learning Objectives: Understand the benefits of using the GEOWEB Soil Stabilization System to stabilize surfaces for unpaved roads, drill pads, and work platforms using low-quality fill or sand.
