Trails and greenways play a vital role in communities by preserving and creating open spaces for low- or no-cost outdoor recreation. Trails designed with permeable surfaces rather than traditional concrete or asphalt allow for better environmental and stormwater management. Since recreational trails can be designed for a wide range of uses, including motorized and non-motorized traffic, it’s important to utilize a solution that is durable and flexible. In this webinar, we will explore a variety of soil stabilization and porous pavement products that can be tailored to the needs of individual projects—including those with hard-to-access areas and stormwater concerns. Multiple types of infill and anchoring methods allow for project customization, resulting in low-maintenance and attractive trails for years to come. Trail embankment stabilization is another consideration when designing recreational trails. The embankments may be part of the existing natural terrain or result from cuts made to accommodate the construction of the new trails. Depending on embankment steepness, the GEOWEB® System can be used to stabilize slopes with single-layer protection or near-vertical, tiered retaining walls with a vegetated fascia. GEOWEB green slopes and living walls protect against erosion, reduce stormwater runoff, and create a natural environment for sustainable vegetation. Learning Objectives:… Read more »

Through 3D confinement and the strengthening of infill, less material is required and on-site waste rock can be used. The GEOWEB system offers increased speed of operation, lower maintenance, safer installation, and lower total cost of ownership. Learning Objectives: Understand the benefits of geocellular confinement for high-performing, long-lasting mine infrastructure. Explore mine applications for geocells in haul road, slope, channel, and containment pond solutions. Learn how 3D geocellular confinement can produce higher performance and lower maintenance mine site solutions.
As our cities expand and new or renovated buildings are opened, it is vitally important to consider the need for emergency access of all areas of the community. Fire truck and emergency vehicle roads are necessary to allow these public health services access during an urgent situation. Although these drive lanes are intended for infrequent use, they must be designed to withstand the heavy loads of operational vehicles. In this webinar, we will discuss how to incorporate geosynthetic reinforcement, including the GEOWEB® geocells, and rigid porous pavers like the GEOPAVE® Gravel Pavers and GEOBLOCK® Grass Pavers in constructing durable access roads. The discussion will include solutions for an array of applications, including concrete and asphalt support, gravel surface lanes, and vegetated surfaces for hidden emergency access roads. Additionally, project case studies will highlight the versatility and effectiveness of these technologies. We’ll show how the GEOWEB® geocells can be used in soft soil environments, and in areas with extreme temperature variations, from cold to hot climates. Furthermore, we will explore how the GEOPAVE Gravel Pavers and GEOBLOCK Grass Pavers have been successfully utilized in environmentally sensitive locations, contributing to green building initiatives and sustainable urban development.

Ballast degradation can rapidly occur under heavy axle loadings over soft subgrade soils. Ballast failure can lead to speed reductions, track downtime, and costly maintenance and repairs. 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.

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.

Today’s increasingly stringent environmental regulations continue to create the need for Low Impact Development (LID) and Green Infrastructure (GI) management on project sites. New and innovative methods must be used to limit hard surfaces such as parking lots, walkways, and emergency access lanes. Land access is at a premium, and areas of environmental protection are increasing, requiring builders and engineers to work with regulators to utilize both LID and GI practices. Porous pavements are an easy and economical way to reduce the impervious surfaces on-site and restore the natural water cycle close to its source. Porous pavements have the added benefit of reducing the size of above-ground detention ponds and minimizing conveyance and treatment infrastructure. Stormwater diversion channels, roadside swales, and drainage ditches can be constructed with low-maintenance solutions, protecting against erosion and overflow concerns. Living green walls increase the amount of vegetation on-site, help promote water filtration from higher elevations, and allow access to more 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… Read more »
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.
